15.4. Pumping of hydraulic system of the drive of brakes


  1. Uncover a compensation tank and fill it with brake fluid.

Brake fluid dissolves paint, plastic and isolation of wires therefore at casual hit of liquid on a paint and varnish covering of the car or its components wash out their large number waters.

When pumping under pressure do not press a brake pedal

  1. Turn off a cover from the union of pumping of the working brake cylinder and attach to it one end of a transparent hose, and insert other end of a hose into the glass capacity of sufficient volume half filled with brake fluid.
  2. Slowly press a brake pedal several times.
  1. At the pressed brake pedal a key weaken the union of pumping and let out the air from hydraulic system. Tighten the union of pumping and release a brake pedal.
  1. Repeat operations 3 and 4 until there is a brake fluid without vials of air.
  2. Tighten the pumping union. Inhaling moment: 7–9 N • m.
  1. You carry out removal of air to the sequences, shown in the drawing.
