How to pump the brakes to one. How to properly brake

From the article you will learn how to pump the brakes to one. This procedure is not complicated, but it will take some time. The fact is that it is necessary to completely evacuate the air from the brake system of the car. In this article, we will look at step by step how to completely expel air from the tubes and other mechanisms of the system. In addition, you will find out what time interval between changing the brake fluid. And also get an answer to how to recognize that there are air jams in the system.

When to pump the system

Do this if you are repairing any part of the brake system. In particular, the pumping is carried out in the event that the main or working cylinders or calipers are replaced. Needless to say, pumping is necessary in the event that a scheduled replacement of the brake fluid is made. At tuning and modernization also it is necessary to get rid of air plugs. Even the elementary replacement of rubber tubes leads to the fact that it is necessary to drain the liquid. Therefore, there must be traffic jams with air. Therefore, you need to know how to properly brake the brakes. But there are also emergency situations. In the event that the system becomes depressurized, for example, if hoses or metal tubes are damaged. Often, if the main brake cylinder is heavily worn, fluid leaks.

How to understand that there is air in the system

And now a few words about how to detect air bubbles in the car's brake system. The fact is that you will not be able to see these bubbles. But their presence will be felt when driving a car. Note that it is forbidden to modify the rules of the road in such constructions as the braking system. This is one of the main design components, which affects not only ride and comfort, but most importantly - the safety of the driver and passengers. Therefore, it is necessary to make a timely replacement of fluid in the system, therefore, it is important to know how to pump the brakes. "Toyota" or the domestic "Tazik" - it does not matter, because the design of the hydraulic brake system is identical. If braking deteriorates, as well as when the pedal is free, the braking distance, and strong feedback (in the pedal), it is necessary to diagnose the system. The first signs that there is air in the system is the excessive softness of the pedal, as well as its large free stroke.

When the brake fluid changes

So, now it is necessary to answer the most urgent question for any motorist - when is it necessary to replace the brake fluid? And how to pump the brakes to one, is it possible? The answer to the first question will be two, depends on what mileage the car passes each year. If for one year you travel from 20 to 30 thousand km, then the period of replacement of the brake fluid should be approximately 2-3 years. But if the car is operated very often and its mileage is many times higher than the above, it is necessary to adhere to other data. You need to change the fluid and pump the brake system every 60 thousand km. At the same time all the work can be done independently, without resorting to the services of car repair shops. The maximum that you need is the availability of the tool and, preferably, the help of a partner.

What you need to know before starting work

Before starting the repair, you need to know a few points that will be useful in the process. It is very important to know how to properly brake the brakes on a car. Please note that it is necessary to use liquid only of the manufacturer and brand, which was previously in the system. In the event that you purchased a car recently and for this reason do not know what kind of liquid was in the tank, you need to resort to the recommendations of the automaker. It is likely that the previous owner also turned his attention to these recommendations. In addition, you will need a partner who will help you pump the brakes. Its function will be to timely apply the brake pedal, thereby creating pressure in the braking system.

Tips for pumping

In the article you will learn how to pump the brakes on the VAZ and any other car. Absolutely does not matter which machine manufacturer, the design of the brake system is the same for all. If you only change the liquid, it is advisable to carefully inspect the elements of the system, make sure that there are no leaks anywhere. Pay special attention to rubber tubes that have the property of cracking and, of course, fail. In these places there are leaks of the brake fluid, depressurization occurs, which can lead to an emergency situation. In the event that your car has an anti-lock system, it must be completely turned off. To do this, you need to open the fuse box. Then find in it a fuse, which is responsible for the ABS power supply. As a rule, it has a rating of 30 or 40 amperes. And now about how to pump the brakes to one, without resorting to the service station.

How is the bleeding done?

So, now it is necessary to expel all air from the system. Before proceeding to work, it is necessary to make sure that in the expansion tank the liquid level is at the maximum mark. If this is not the case, make sure to top up the liquid. Then the rear axle is completely hung out to unlock the pressure regulator. To do this, it is necessary to install a flat screwdriver between the pressure regulator piston and the plate. The main thing - do not forget to remove it after the completion of all repair work. Pay attention to that on each support and working cylinder there are bleeding nuts. That's how to properly pump the brakes (VAZ or foreign car - it does not matter).

Be sure to clean them thoroughly before accumulating any dirt. Then remove the protective rubber cap and put a small piece into the hoses. Ideally suitable tube, which is used in the windscreen cleaning system. Also you will need a small jar, in which pour a small amount of brake fluid. 50-100 grams will be quite enough. The second end of the hose, which is put on the bleeder, must be immersed in a jar of liquid. Thus, all the brake mechanisms of the vehicle are pumped. What is the manufacturer of the car, it does not matter. Everything is done by analogy with this manual. And now about the procedure in more detail.

How to expel air from the system

Since it is difficult to pump the brakes to one (you have to run a lot, press the pedal, then fix something with it in the squeezed position), it is better to use the services of a partner. At the wheel the assistant settles down, after which he presses the pedal three or five times. This should be done slowly enough, the interval between shocks should be about one and a half to two seconds. When the assistant presses the last, fifth time, the pedal must be fixed in the extreme squeezed position. Note that the pedal is held in this position until you turn the bleeder half a turn. At the same time, you will see that the liquid is moving along the hose. There are air bubbles in it, from which it is necessary to get rid of. After the liquid has ceased to flow from the tube, it is necessary to tighten the union. The assistant can now remove his foot from the brake pedal. This cycle of procedures is carried out until as long as there is not a single air bubble in the liquid. And always pay attention to how much brake fluid is in the expansion tank. Do not let it drop to the minimum mark. After completing the bleeding of one circuit, be sure to tighten the union, tighten the rubber cap. Similarly, all other brake mechanisms are pumped. And to pump the brakes on UAZ and BMW is possible according to this manual.
