Pumping of brakes

Pumping of brakes is required, if the system was opened in any place, or air got to it some other way. Before pumping of brakes it is necessary to remove dirt and foreign matters from gates of pumping and uncover a compensatory tank.

If only one wheel cylinder or a support was disconnected, it is usually enough to pump over only the corresponding contour, i.e. a forward left and back right brake or a forward right and back left brake. Otherwise pumping can be begun both with lobbies, and from back brakes, however it is best of all to adhere to the sequence recommended by the producer: back left, forward right, back right and forward left brakes. For pumping without assistance in autoshops there are many devices. When using one of such devices it is necessary to be guided by the instruction to it. Otherwise it is necessary to resort to the help of the assistant.


  1. After removal of a boot put on the corresponding gate of pumping a transparent hose. Other end of a hose lower in a bottle filled with a quantity of brake liquid.
  2. Ask the assistant to press a brake pedal to a floor. Open the pumping gate on a half of turn when the pedal is at a floor. Watch brake liquid following from a hose.
  3. When in liquid air vials will cease to appear, means, air is removed. At the last muscleman leave a pedal at a floor and close the pumping gate. Slowly release a pedal.
  4. The same operation do on other gates of pumping in the set sequence.
    It is necessary to pay attention that is necessary to watch level of brake liquid in a tank that air could not get to system through a tank. Never fill in in a tank the liquid extorted from system. Do not use brake liquid, long time being in open ware.
