Perhaps the most important part of any car is the braking system. It is she who allows you to slow down the car in time, ensuring traffic safety. Today, most passenger cars use a hydraulic braking system. And cars of the Samara-2 family are no exception. Car owners should know under what circumstances the VAZ-2115 brakes should be bled and how to do it correctly. All this - later in our article.

Signs to look out for

When should this operation be performed? The main reason that leads to pumping is the air that has accumulated in the system. It can get inside for various reasons. As a rule, this is a malfunction of the brake cylinders or leaks in the hoses. Very rarely, air enters due to a weak connection of fittings, but this possibility is not worth it either.exclude.

How can I tell if there is air in the system? The driver will notice changes in the behavior of the car. So, when you press the pedal, the car will not slow down as efficiently. And the pedal itself will be more sluggish and have an increased stroke. The critical situation is when it completely falls into the floor, and the car barely slows down. In this case, it is urgent to pump the front and rear brakes of the VAZ-2115.

Also, this operation is required when changing the brake fluid. If it has not been updated for more than three years or has become black, it definitely needs to be replaced. In addition, some fluids are also changed when buying a car in the secondary market, when there is no confidence in the reliability of the system. Another pumping may be required for any work on the brake system. This may be the replacement of the tank, the working or master cylinder, hoses and other elements. It is not pumped only when replacing the pads, since the working cylinders are only recessed here (as is the case with the front disc mechanisms, and with the rear drum mechanisms).

Pumping scheme

How to bleed the brakes on the VAZ-2115? To do this, you need to know the sequence of work. They operate in a criss-cross pattern. That is, the air on the rear right wheel is first removed. Next, go to the front left. After that, the rear left is pumped, and then the front right.

Required tools and materials

To get to fittings in the absenceinspection hole, we need to unscrew the wheels. Therefore, you need a jack, stops and a balloon wrench. If there is a pit or overpass, the wheels can not be unscrewed. You will also need new brake fluid. On cars of the Samara-2 family, RosDot of the fourth class is used. In addition, we need a plastic bottle and a hose that will be put on the fitting (so that the liquid does not splash in different directions, but goes into a certain container). To unscrew the fitting, you need a regular key for 8.

Preparation for surgery

So, we put the car on a pit or on a flat surface, then open the hood and remove the brake fluid level sensor connector. Then unscrew the cap and add liquid to the maximum level. After that, screw the lid.

Please note: if you use a lift during work, when bleeding the rear brakes, you need to place a slot in the brake force regulator (it is also called a “sorcerer”). To do this, you can use a screwdriver, setting it between the rod and the bracket.

When bleeding the front brakes, this slot must be removed.

How to bleed the brakes on the VAZ-2115? During the work we need one assistant. He will press the brake pedal on command.

Getting Started

Let's look at how to pump the brakes on the VAZ-2115 with your own hands. So, first we need to find the fitting on the back of the rear wheel drum.

It will be covered with a protective cap. We need to remove the last one. Next onfitting, put on the hose and direct it into a plastic bottle. After that, we need the help of a second person who, on command, will press the brake pedal several times. It is necessary to do this about four to five times with an interval of one to two seconds in order to create pressure in the system. At the last press, the pedal is held in the floor. At this point, we carefully unscrew the fitting. It is important to unscrew it smoothly, since at first the liquid will go under very high pressure. As the fluid comes out, the helper will feel the pedal sink into the floor.

We need to monitor the amount of air in the fluid. If it was with a large number of bubbles, the procedure must be repeated again. Before you create pressure with the pedal, the fitting must be tightened. Further, everything is according to the knurled scheme. The assistant holds the pedal, and we unscrew the fitting and look at the condition of the liquid. If it comes out quietly, does not “spit”, then there is no more air in the circuit. On this, you can twist the fitting and put a protective cap on it.

How to pump the brakes on the VAZ-2115 further? After that, they move on to the next, now the front wheel.

But before you pump the brakes on the VAZ-2115, you need to add fluid, since part of it was poured through the fitting. The flow diagram is the same. First unscrew the fitting, put on the hose, create pressure and unscrew the mechanism. And so on until normal liquid flows.

Conclusion

So, we have considered how to pump the brakes on the VAZ-2115 ourselves. As you can seethis operation is not very difficult. Therefore, at the first sign of a soft pedal, you need to take care of removing air from the system. It is also worth inspecting the condition of the hoses and cylinders, since after pumping the problem may recur. Air is removed only when the brake system is working.
