brake system of the car is almost the most important in its composition, and in driving safety, it plays a key role.We rarely notice the brakes, because they were made for us as common as, for example, television, refrigerator, or other objects that surround us in everyday life.For normal operation of this system requires a complete tightness is ensured thanks to the release of air from conducting tubes and hoses.
In this article, we will briefly look at how to pump the brakes.This process is quite time consuming, and therefore requires certain skills and tools.To begin with talk about the theoretical side of the issue.We all know that the unique properties of the liquid - it is their incompressible, it is used as the basis for the entire system.So, when you press the pedal, we push the piston, which is in the master cylinder.By branching off pipe in which the brake fluid pressure moves the piston to the caliper and the working cylinder.This pressure must be said, sometimes up to 3 MPa.Once in the caliper or in the working cylinder fluid transmits the pressure to the piston, and it, in turn, - a brake shoe.
now look at how to pump the brakes on the practice.Generally, there are a variety of ways.For their implementation, various tools that allow one to pump the brakes.Let's begin with a simple.The first way to talk about how to pump the brakes with the assistant.For this optional lift or other sophisticated equipment.First you need to fill the tank, located above the main brake cylinder.Now we have to start from the farthest wheel.The assistant should make a few taps on the pedal - it will create pressure in the system.Now the union is put on a support hose, and he unscrewed.Then he twists (it all happens when the pedal is pressed), then the procedure is repeated for as long as the hose will not cease to do any air bubbles.Then go to the other wheel on the same axle.With him perform all the described actions and go to the other axle.At this time, it should constantly monitor the level of liquid in a tank.This is one method of how to bleed the brakes.
Consider another.He will tell you how to do it yourself.Bleeding the brakes without an assistant - it's not such a difficult job, but it takes a little more time and requires a large supply of brake fluid.The car should be set on a hill, it is better if it will lift.Further, one end of the hose should be put on the union, and the second - in the capacity of a vacuum.With this role perfectly cope pear 250 ml.Now unscrew the union, and then do some pedal is pressed.Here it is necessary to constantly monitor the vacuum.If it is not, then the air goes back into the system, and have to do all over again.On the other wheels of the same course of action.
Here are two basic ways that can be useful during pumping the brakes.In addition, it is worth remembering about the harmfulness of the brake fluid, and wash your hands thoroughly after handling.The rubber gloves do this is undesirable because the rubber under the influence of such a liquid melts may be burned.
