10.15. Pumping of brake system

GENERAL INFORMATION

Prevention

This operation is carried out together, with observance of safety measures as brake fluid is toxic.


Sequence when pumping all system:

 – 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 of this wheel.


Prevention

For a dolivka or replacement to use only new brake fluid.


PERFORMANCE ORDER
1. To clear of dirt and raise dust the valve of production of air on a wheel from which air will be removed.
2. To check and if necessary to add brake fluid in a tank to the maximum mark.
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 end of a hose in the pure transparent vessel which is partially filled with brake fluid.
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 the valve of production of air on 1/2–3/4 turns. Thus in the liquid following from a hose vials of air will be visible. After the liquid effluence from a hose stops, to wrap densely the valve of production of air and to release a brake pedal.
6. To repeat item 3 until allocation of bubbles from the following liquid completely does not stop. Thus it is necessary to watch the level of brake fluid in a tank and to add brake fluid to a tank, without allowing bigger decrease in level in it.
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.
9. To add in a tank to necessary level brake fluid.
Prevention

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