The brake system of the car is practicallythe most important in its composition, and in driving safety it plays a key role. We rarely notice the work of the brakes, because they have become for us as normal as, for example, a TV set, refrigerator or other items that surround us in everyday life. For the normal operation of this system, complete tightness is required, which is provided by the release of air from the conductive tubes and hoses.
In this article we will briefly consider how to pumpbrakes. This process is quite laborious, so it requires certain skills, as well as tools. First, let's talk about the theoretical side of the issue. We all know that the unique property of liquids is their incompressibility, it is used as the basis of the entire system. So, when you press the pedal we push the piston, which is in the main brake cylinder. From it, the tubes go out, through which the brake fluid moves under pressure from the piston to the calipers and to the working cylinders. This pressure, I must say, sometimes reaches 3 MPa. After getting into the support or into the working cylinder, the liquid transfers the pressure to the piston, and it, in turn, to the brake shoe.
Now consider how to pump the brakes onpractice. In general, there are many ways. To implement them, various devices are used that allow one to pump the brakes. Let's start with a simple one. The very first method tells how to pump the brakes with an assistant. For this, a lift or other complex equipment is not required. To begin with, you need to fill the tank, located above the main brake cylinder. Now we must start from the farthest wheel. The assistant must make a few depressions on the pedal - this will create pressure in the system. Now the hose is put on the caliper of the caliper, and it is unscrewed. Then it is twisted (all this happens when the pedal is depressed), after which the procedure is repeated until air bubbles cease to flow into the hose. Further we pass to another wheel of the same axis. With him, we carry out all the described actions and move to the other axis. At this time, you should constantly monitor the level of fluid in the tank. This is one way to pump the brakes.
Consider another.He will tell you how to do it yourself. Bleeding the brakes without an assistant is not such a difficult task, only it takes a little longer and requires a larger brake fluid supply.
Here are two main ways that canuseful when pumping the brakes. In addition, it is worth remembering about the harmfulness of the brake fluid and thoroughly wash your hands after work. In rubber gloves do all this undesirable, because the rubber under the action of a similar liquid melts, there may be burns.
