According to the technical inspection card, the brake fluid on the Lada Priora should be replaced every 45 thousand kilometers or once every 2 years. Over time, during operation, the fluid loses its properties, which affects braking efficiency. Used brake fluid is dark in color, while new brake fluid is light in color.

Which brake fluid to choose for Priora

The manufacturer fills it with DOT 4. The most popular brake fluids among buyers are ROSDOT 4 and NEVA-M. The first option is more expensive, the second is cheaper. For cars with and without ABS, it is recommended to use different types of fluids.

• DOT-4 plus - for cars without ABS
• DOT-4 class 6 - designed for modern braking systems (ABS, ESP, VSA)

Depending on the capacity, the cost of the brake fluid indicated above is from 50 to 150 rubles.

You can also add DOT 5.1 fluid. It has a lower viscosity than the above samples, as well as a higher boiling point and, according to manufacturers, changes once every five years.

It is prohibited to mix liquids of different types with each other!

Do-it-yourself replacement of brake fluid on a Lada Priora

To replace you will need:

• The brake fluid itself
• For removing old fluid syringe
• dry rag
• container for old liquid
• rubber hose, the diameter of which should be suitable for the bleed fittings on the wheels
• Special brake wrench 8 by 10 mm

Now let's fill in a new one brake fluid into the tank to the max. level.

Now you need to completely remove the old fluid from the system by pumping it and filling it with new fluid.

Sequence of pumping brakes on Priora

1. Rear right caliper
2. Rear left caliper
3. Front right caliper
4. Front left caliper

This is the order in which you should bleed the brake system.

Do-it-yourself bleeding of the brake system

Each wheel has a special drain fitting to remove air from brake system. It is through this that you need to remove air and old liquid.

A rubber hose prepared by us is put on the fitting and lowered into a container to drain the old liquid. In this case, the hose in the dish must also be in the liquid so that there is no air leakage.

Using a brake wrench, unscrew the fittings on each wheel sequentially and pump the old fluid out of the system until it is clean. You will need an assistant who will pump the brake pedal; your task is to drain the old fluid.

That is, the assistant pumps the brake pedal 5-10 times and presses it. You unscrew the fitting a little and drain the liquid. The assistant pumps the pedal again, then presses it and drains the liquid again. And this must be done with each wheel.

When bleeding the brakes, keep an eye on the fluid level in the reservoir; it should not be empty.

After bleeding, make sure that the brake fluid in the reservoir is between MIN and MAX. This completes the replacement of brake fluid on the Lada Priora.

Carry out maintenance of the brake circuit together with a partner; it is extremely difficult to “bleed” the system alone. To ensure maximum access to the circuit, use an inspection channel or roadside overpass.

Step-by-step instructions for replacing brake fluid on a Lada Vesta

1. We install the machine within the perimeter of the repair area.
2. Unscrew the wheel.
3. We clean the working area of ​​the hub from dirt.
4. A partner pumps the brake pedal.
5. Fixes it in the lower position and holds it.
6. We unscrew the grease fitting on the hub.
7. We drain (bleed off) excess DOT fluid.
8. Pump the pedal again.
9. We bleed the air again.
10. We are replenishing the missing amount of DOT.
11. We repeat the pumping procedure as necessary.

Where is the brake caliper located?

In cars of the Lada Vesta family, the grease fitting is located on the brake caliper. Expansion tank for topping up DOT - in engine compartment, on the right side.
The standard location of the caliper and grease fittings on each wheel is identical.

Fluid replacement resource. Consequences of missing deadlines

AvtoVAZ engineers recommend updating DOT every 45,000 km. In practice, the interval is reduced to 35–40 thousand km due to the poor quality of the fluid.
The consequences of untimely replacement of DOT can be different, even an emergency.

Signs that replacement is needed

• decreased braking efficiency;
• increase in braking distance;
• increased pedal free play;
• stiffness of movement, low information content of the pedal;
• on dashboard the indicator indicates a malfunction in the brake circuit;
• The brake fluid level is below the minimum permissible in expansion tank.

Sequence of actions when replacing fluid yourself

Necessary tools, materials:

• key to “10”, “14”, cylinder to “17”;
• rags;
• additional lighting;
• Pillbox for filling;
• new brake pads as needed.

Algorithm of actions:

1. We hang the car with an electric lift.
2. Open the hood.
3. Unscrew the cap of the brake fluid expansion tank.
4. We remove the wheel.
5. In the cabin, a partner pumps the brake pedal and fixes it in the lower position. Waiting for commands.
6. Clean the surface of the back of the brake caliper, remove dirt, and wipe dry.
7. Using a key set to “10”, unscrew the grease fitting and bleed out the air along with the liquid.

1. We tighten it and give a command to our partner to repeat the pumping procedure.
2. We repeat the step again.
3. We replenish the missing amount of bunkers in the expansion tank.

After completing bleeding of one wheel, we immediately proceed to the next one according to the scheme:

• Front left – rear right;
• Front right – rear left.

The algorithm outlined above does not allow the complete replacement of bunkers in the contours. The design of the car is such that it is impossible to “flush” the system without major dismantling.

Many service station mechanics use a channel in the hydraulic drive to replace brake fluid:

1. From the front of the engine we find the hydraulic drive fitting.
2. Remove the plastic cap from it.
3. We put on a hose, one end of which is lowered into a container with liquid.
4. We recess the bracket.
5. Pull out the plastic tube.

1. The system has been depressurized and the bunker leaks out of the hose under pressure.
2. As soon as the level in the expansion tank drops below the minimum, we replenish the missing amount.
3. We repeat the cleansing procedure until the color of the DOT becomes transparent.

The volume of bunker that is filled into Lada Vesta is 1.5 liters.

Video - Self-replacement

We carry out the work on an inspection ditch or overpass.

Unscrew the filler cap of the tank.

We pump out the old liquid from the tank with a syringe or rubber bulb.

Fill the reservoir with new brake fluid.

Attention! Brake fluid that gets on paintwork, plastic parts and vehicle wiring may cause damage. Remove it immediately with a clean cloth.

It is necessary to bleed the brake system hydraulic drive until new fluid (lighter than the old one) begins to come out of the bleeder fittings of all working cylinders.

We carry out pumping to replace the fluid with the engine not running, first on one circuit, and then on the other in the following sequence:

• brake mechanism right rear wheel;
• left brake mechanism front wheel;
• left rear wheel brake;
• brake mechanism of the right front wheel.

Before pumping, check the level of working fluid in the hydraulic brake reservoir. If necessary, add liquid.

We bleed the brakes with an assistant. Cleaning the bleeder fitting from dirt brake mechanism right rear wheel.

Remove the protective cap from the cylinder fitting of the rear right wheel.

An assistant must vigorously press the brake pedal all the way 1-2 times and keep it pressed.

Using the “8” wrench, unscrew the bleeder fitting 1/2-3/4 turn.

In this case, liquid will flow out of the hose, and the brake pedal should be pressed all the way.

As soon as the liquid stops flowing from the hose, tighten the fitting, and only after that can the assistant release the pedal.

We repeat this operation until new brake fluid (lighter than the old one) comes out of the fitting.

We remove the hose, wipe the bleeder fitting dry and put a protective cap on it.

Remove the protective cap from the brake bleeder fitting of the left front wheel.

We put a hose on the fitting, and immerse its free end in a container partially filled with working fluid.

We bleed, as described above, the brake mechanism of the left front wheel, unscrewing the bleeding fitting with a “8” key.

Similarly, we bleed the brake mechanisms of the other circuit.

When pumping, you need to monitor the fluid level in the tank and add fluid if necessary.

After bleeding the hydraulic brakes, bring the fluid level in the reservoir to normal.

There is an even simpler option for replacing brake fluid. This method does not require the presence of an assistant. In this case, a certain supply of brake fluid is desirable (at least 1 liter).

We place the car on an inspection ditch or overpass and provide free passage between the place where you can refill the brake fluid reservoir in the engine compartment and the brake cylinders of all four wheels.

Use a rubber bulb or syringe to pump out the brake fluid from the reservoir. Top up new fluid to the top edge. To speed up the process (to release fluid from all cylinders at once), it is advisable to select four pieces of tubes that fit tightly onto the bleeder fittings of all cylinders. We lower the free ends of the tubes into small transparent bottles.

We unscrew the fittings of all brake cylinders. We make sure that the liquid has flowed through all four tubes. We control the decrease in fluid from the reservoir located on the brake cylinder and immediately replenish the reservoir. We observe an increase in the level of liquid in bottles located near the wheel brake cylinders.

It is necessary to move several times from the position of observing the flow of fluid from the brake cylinder fittings to a position where you can check and replenish the fluid level in the reservoir located on the brake cylinder in order to prevent the reservoir from drying out.

Usually the level rises most quickly in the bottle into which the hose coming from the brake cylinder of the front left wheel is lowered. As soon as there is about 200 ml of liquid in the bottle of the front left wheel, wrap and tighten the fitting of this cylinder. Next, we wait for the same result for the front right wheel cylinder, and tighten its bleeder fitting in the same way. The process can be completed after 200-250 ml of liquid comes out through the fitting of each rear wheel.

We make sure that all fittings are tightly tightened. We put on protective caps. Check the fluid level in the master cylinder reservoir.

The Lada Granta car has a braking system (pipes, brake cylinders, vacuum booster, brake regulator, brake pads, etc.) similar to the Lada Kalina car. For effective and safe braking, the Lada Granta uses a diagonal, double-circuit piping system, which means that the first circuit blocks the wheels - the right front and left rear, and the second circuit - the left front and right rear. The front wheels are equipped with disc brakes, the rear wheels are equipped with drum brakes. The master cylinder is controlled through a vacuum brake booster, which increases the efficiency of operating the braking system by pressing the brake pedal. Depending on the configuration of the Lada Granta car, the braking system may be equipped with an anti-lock braking system (ABS). The Lada Granta has hand brake, which blocks the rear wheels (spreads the brake pads in the drums). The pads are moved through a system of levers by moving a steel cable attached to a lever located inside the car. The vacuum booster on the Lada Granta car (shown in Fig. 1) is of the diaphragm type. The diaphragm is the separating partition between the rarefied atmosphere created in the vacuum amplifier and external atmospheric pressure. The pressure difference reduces the force on the brake pedal. When the brake pedal is released, the vacuum and atmospheric chambers communicate with each other through a special valve.

We bleed the hydraulic drive of the brake system after its repair, which resulted in a violation of the tightness of the system and if air is suspected of getting into the system. In the latter case, you must first determine and eliminate the cause of air entering the hydraulic drive and only then start pumping it. The presence of air in the hydraulic drive of the brake system is determined by the behavior of the brake pedal: it becomes soft (you can’t feel the stop at the end of the pedal stroke) and drops below its normal position.

To complete the work you will need an assistant, as well as:

A special wrench for the bleeder fitting or an 8 mm socket wrench;

Transparent vinyl tube of suitable diameter;

Container for draining brake fluid;

Inspection ditch or overpass (preferable).

We prepare the car for work.

Disconnect the wiring harness connector from the brake fluid level sensor connector and remove the reservoir cap

To prevent air from entering the hydraulic drive of the brake system, when bleeding the drive, make sure that the brake fluid level in the reservoir does not fall below the mark MIN.

If rear axle If the vehicle is suspended (the vehicle is on a lift or mounted on stands), the pressure regulator will block the path of brake fluid to the rear wheel cylinders. Therefore, to bleed the rear wheel cylinders, it is necessary to open the regulator valve.

To open the pressure regulator valve, insert the blade of a slotted screwdriver between the lever and the plate, recessing the regulator rod.

9. Bleed the brakes of the remaining wheels, if necessary.

If there is no air in the system, the brake pedal should be “hard”, i.e. when pressing, go no more than half the distance to the floor.

Replacing brake fluid

To complete the work, you will need an assistant, as well as a rubber bulb.

1. Prepare the car and necessary equipment to perform the work.

2. Remove the tank cover

To prevent air from entering the hydraulic drive of the brake system, when replacing the brake fluid, make sure that its level in the reservoir does not fall below the mark MIN.

3. Use a blower to remove the working fluid from the master brake cylinder reservoir.

4. Fill the tank with new fluid up to the top edge of the tank.

5. We pump the circuits of the hydraulic drive system, starting with the rear wheels of the car.

6. We pump each wheel cylinder until new (lighter) brake fluid begins to emerge from the fitting.

7. After replacing the fluid in both circuits, we check the operation of the hydraulic drive and bring the fluid level in the master brake cylinder reservoir to normal.

Replacing brake fluid in the hydraulic brake drive system with modern models Lada (Granta, Kalina, Priora, Niva 4x4, Vesta and XRAY) should be performed once every three years or after 45,000 km (whichever comes first). On Lada Largus - once every six years or after 90 thousand km. mileage All cars have the same type of brake design, so the process for changing brake fluid is similar.

Replacing brake fluid (method No. 1)

The traditional, familiar way of replacing brake fluid in the brake hydraulic drive system is by substitution. Leveling procedure for modern cars Lada (Granta, Kalina, Priora, Largus, Vesta and XRAY) - rear right, front left, rear left, front right wheels. For Niva 4x4 - rear right, rear left, front right, front left.

1. Pump out the liquid from the tank (with a syringe or rubber bulb);
2. Fill in new brake fluid;
3. Remove the protective cap from the brake fitting, loosen the fitting with a wrench and put on the hose (immerse the other end in a container half filled with liquid).

To force the brake fluid to flow out of the fitting, you will need an assistant, who must press the brake pedal 1-2 times and then hold it with his foot. Instead of an assistant, you can put a spacer or create pressure in the tank using a special lid or lungs (covering your mouth with a rag). We discussed such methods of bleeding brakes without an assistant earlier.

As soon as a lighter liquid runs instead of a dark liquid, we move to another wheel according to the contour diagram (see above). Periodically check the level of brake fluid in the reservoir and add it if necessary, otherwise air will enter the brake system.

Replacing brake fluid (method No. 2)

On certain cars (for example, Lada Vesta, Largus, XRAY with French JH3/JR5 gearboxes) there is an easier way to change the brake fluid - use a clutch bleeder. It will take less time, but the brake fluid will only be partially replaced.

We put a hose on the fitting (immerse the other end in a container half filled with liquid). Next, you need to depressurize the pipeline; to do this, lower the bracket down (No. 4) and pull out the plastic tube (No. 1, to the right) by 7-9 mm. We drain about 150 ml of liquid (with or without an assistant, see above) and seal the circuit back. Check the brake fluid level in the reservoir. This process is in detail.

Let us remind you that brake fluid that gets on the paintwork, plastic parts and wiring of the car can cause damage. Immediately clean surfaces of brake fluid. Do you change the brake fluid yourself? What difficulties did you experience during the first replacement? By the way, do you know which brake fluid is better to choose?

Brake fluid is used not only to organize the operation of the braking system, but also to ensure uninterrupted movement of the clutch mechanisms, as is the case with the Lada Kalina car.

This is explained by the fact that in this model the clutch and brake mechanisms have the same operating principle. By pressing the pedal, brake fluid is injected into the brakes, as well as into the clutch mechanism, which ensures braking of the entire car.

What brake fluid should be used on Lada Kalina

During operation, it is recommended to use brake fluids produced by ROSDOT 4 and NEVA-M, since their products are of the highest quality and most suitable for this car compared to others.

The difference between them is the cost, and the first option will cost a little more. As for the initial fluid that is poured into the car, AvtoVAZ uses DOT 4.

In this case, the liquid may differ in composition depending on the vehicle for which it is intended. Below is a table with the brake fluids used.

also in Lada Kalina DOT 5.1 can be used. It differs from the others in having a more viscous consistency and a higher boiling point. According to the manufacturer, this fluid is replaced every five years.

In the case of Kalina, it is recommended to change the fluid approximately once every 45 thousand kilometers or every two years. This is explained by the fact that during operation the fluid loses its original properties, which negatively affects the operation of the brake system elements.

How to fill brake fluid correctly

First of all, it is worth noting that spoiled brake fluid can be identified due to its darkened color and thickened consistency. To replace, you will need the following materials and tools:

• New brake fluid.

• Syringe for removing old fluid.
• Dry cloth.
• Container for draining old fluid.
• A rubber hose, the hole of which must fit the bleed fittings on the wheels of the car.
• Brake wrench 8 by 10 mm.

Where is the liquid located?

You can find brake fluid in the brake hoses. It is also found in:

• master cylinder;
• brake reservoir.

It is worth noting that almost every experienced Lada owner Kalina knows where the brake system is located and how it works. If there is no such knowledge, then it is better to study the structure of the car before replacing it or still seek help from professionals at a service station.

When choosing the option of self-replacement, the first step is to carry out preparatory work:

• Place the car on an overpass or pit.
• Turn off the engine and install wheel chocks.
• Disconnect the terminals from the battery.

Drain

First of all, during replacement, the old fluid is drained. It is performed as follows:

• The lid of the tank needs to be unscrewed. It contains brake fluid. The lid can be put aside, but it is better to place a rag under it, since the composition is in excellent contact with surrounding surfaces, without affecting them very well.

• The next step is to unlock the pressure regulator on rear wheels, if this turns out to be necessary. To unlock this design, you will need to install a screwdriver between the plate and the piston.
• After this, you should prepare a hose and container to drain the old fluid. It is best to use an empty bottle if you don’t have a container at hand. Before draining, it is necessary to clean the fitting from dirt using a brush. Subsequently, a hose will be attached to the fitting.

• Once the fitting is cleaned, you will need to remove the cap from it and insert one end of the hose into the hole, and the other should go into a container or bottle. Then you will need the help of a second person. He will need to get into the car and press the brake pedal several times. This must be done sharply so that the liquid can be drained, but between each press it is necessary to maintain a short break.

• As soon as the liquid stops flowing, you need to pull the hose out of the hole, wipe the fitting with a rag and close it with a lid. In this case, it is important to tighten the cap correctly. So, for example, if during the process of unscrewing it was loosened by 3/4, then it should be tightened by the same amount.

• The final action will be to begin pouring the new compound while tightening the fitting. As soon as new liquid begins to flow out of the existing hole, you can screw the cap on completely.

This fluid drain diagram is for rear brakes. As for the front ones, the procedure is practically no different. The main difference is only in the location of the fittings, but this will not be a problem if you familiarize yourself with the structure of the car and the brake system in advance.

Thus, the brake fluid is drained from both the front and rear brakes, after which it will be possible to begin filling in new fluid.

Bay

It is necessary to add liquid during the draining procedure. In this case, both actions should not be performed simultaneously, but in a certain sequence. In other words, you cannot fill in a new fluid composition until at least half of the old one has been drained.

When carrying out work, several points should be taken into account:

• Do not allow air to get inside the brake system. This leads to a deterioration in the performance of the brake pedal - the resistance changes.
• There should also be no bubbles in the bottle or hose. If such a situation arises, then new fluid cannot be added until the entire brake system has been pumped and air has been removed from it.

Upon completion of the replacement, the necessary elements are reinstalled and checked by turning on the engine. If there are no problems, then the amount of liquid in the tank is additionally checked, and if necessary, top up to the required volume.

Brake fluid in a Lada Kalina car is an important component that ensures safe driving of the entire vehicle.

Therefore, it is worth monitoring the condition of the fluid, as well as its level, in order to avoid serious problems, and replace it in a timely manner. It should also be noted that in some situations, old brake fluid or its leak can become the root cause of a serious accident, since in this case the car’s brakes simply will not work.

We recommend choosing the fluid class recommended by AvtoVAZ, that is, DOT-4. To decide on a brand or manufacturer, you can rely on reviews from VAZ car owners. According to a survey, about 66% of motorists buy brake fluid from RosDOT, Dzerzhinsk. And not in vain, because in the tests of the ZaRulem magazine it is in good positions:

1. SINTEC EURO DOT-6 (class 6)
2. ROSDOT 6 DOT 4 (class 6)
3. SINTEC SUPER DOT 4
4. Lukoil DOT 4
5. Hi-Gear DOT 4
6. ROSDOT 4
7. Sibiria Super DOT 4
8. Rosa 4
9. Felix DOT 4
10. VITEX DOT 4
11. RSQ PROFESSIONAL EURO DOT 4
12. CHIMLUX DOT 4
13. UNIX DOT 4
14. PROMPEK DOT 4

Test results for DOT-4 brake fluids. All brake fluids of the same class are compatible with each other. Are they different from each other? The answer to this question is given by the “Behind the Wheel” experts.

	Boiling temperature "dry" liquid*		Reduced low temperature viscosity**		Present cost per unit of production	Final score
Lukoil DOT 4

* Bigger is better. **Less is better.

Can DOT-3, DOT-4, DOT-5 or DOT-5.1 be mixed?

Differences between brake fluid classes:

• DOT 3 (glycol base) – for relatively low-speed vehicles with drum brakes or front disc brakes;
• DOT 4 (glycol base) – on modern high-speed cars with predominantly disc brakes on all wheels;
• DOT 5.1 (glycol base) - on road sports cars, where the thermal load on the brakes is significantly higher.
• DOT 5 (silicone) on conventional vehicles are practically not used.

Brake fluids DOT 3, 4, 5.1 (color from light yellow to light brown) are interchangeable, but mixing them is not recommended (it is better to complete replacement), properties may deteriorate. DOT-5 (dark red) cannot be mixed, it only mixes with itself. In other words, brake fluids can only be mixed by color.

What brake fluid can you recommend? Is it worth changing the usual DOT-4 class for Lada to others, for example, DOT-5.1? Let us remind you that you can easily find any information about your car by its content (Niva, Priora, Kalina, Granta, Largus, Vesta, XRAY).

Key words: brakes lada xray| Lada Vesta brakes | Lada Largus brakes | Lada Granta brakes | Lada Kalina brakes | Lada Priora brakes | Niva brakes | universal article

Brake fluid Rosdot-4 was developed specifically for cars with disc brakes, taking into account the recommendations of AvtoVAZ specialists. Rosdot-4 is currently one of the best in its class among world analogues. It is recommended to replace the brake fluid after 1.5-2 years. This is due to its high level of hygroscopicity. When using Rosdot-4, it is not recommended to add other brake fluid, as this will lead to a deterioration in the properties of Rosdot-4, and, as a result, a decrease in the efficiency of the braking system.

USEFUL TIPS
In order not to expose yourself in the future to unforeseen expenses for repairing the brake system, or even the entire Lada Granta car as a whole, promptly replace the brake fluid with fresh one. It is very hygroscopic and absorbs moisture from the air, which, in addition to causing corrosion of brake system parts, lowers the boiling point of the fluid itself, and this can lead to brake failure during frequent heavy braking. Do not reuse brake fluid that has been drained from the brake system: it is contaminated, saturated with air and moisture.
If brake fluid comes into contact with wires, plastic or painted body parts, it can cause damage, so always use a clean wiping cloth when pouring. If liquid gets on these parts, wipe them immediately with a clean cloth.

1. Check the brake fluid level in the master cylinder reservoir. When the plug is removed, it should be located between the “MIN” and “MAX” marks marked on the tank body. With the plug installed, the brake fluid level should be at the lower edge of the filler neck, since the brake fluid is displaced by the level sensor float.
WARNING
A gradual decrease in brake fluid level in the absence of leaks most likely indicates the need for replacement. brake pads. Check the condition of the brake pads on your Lada Granta car (see “Checking the degree of wear of brake pads, brake discs and brake drums”). Late replacement brake pads leads to expensive repairs (replacement of brake pads, brake discs and brake drums)!
