10.11. Pumping of brake system



This operation is carried out together, with observance of safety regulations as brake liquid is toxic.

Sequence of pumping:

  – back right wheel;
  – back left wheel;
  – forward right wheel;
  – forward left wheel.

If works only with a brake of one wheel were carried out, it is enough to pump over the cylinder only this wheel.

For a dolivka or replacement to use only new brake FMVSS116DOT4 liquid.

1. To clear of dirt and a dust of the valve of production of air on a wheel from which air will be removed.
2. To check and if necessary to add brake liquid in a tank.
3. To remove a protective cap from the valve of production of air and to put on a valve head a rubber hose for liquid plum.
4. To ship the hose end in the pure transparent vessel which has been partially filled with brake liquid.
5. Sharply to press a pedal of a brake of 4-5 times (with an interval between pressing 1–2 c), and then, leaving a pedal pressed to unscrew on 1/2–3/4 turns the valve of production of air. Thus in liquid following from a hose air vials will be visible. After the liquid effluence from a hose will stop, to wrap densely the valve of production of air and to release a brake pedal.
6. To repeat item 5 until allocation of vials from following liquid completely will not stop.


At air removal from brake system it is necessary to add brake liquid in a tank, without allowing decrease in level in it «MIN» marks are lower.

7. To remove a hose, to wipe the end of the valve and to put on it a cap.
8. To pump over, if it is required, brake mechanisms of other wheels.


Not to use brake liquid repeatedly merged at pumping.

If pumping of brake system is executed insufficiently carefully, by pressing a pedal at the end of its course increased "softness" of a pedal will be felt.
