10.15. Prorolling of brake system

The prevention

The given operation is carried out together, with safety precautions observance as the brake liquid is toxic.

Sequence at prorolling of all system:

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

If works only with a brake of one wheel were spent enough to pump over the cylinder only this wheel.

The prevention

For доливки or replacements to use only a new brake liquid.

1. To clear of a dirt and a dust the valve of release of air on a wheel from which air will leave.
2. To check up and if necessary to add a brake liquid in a tank to the maximum mark.
3. To remove a protective cap from the valve of release 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 partially filled with a brake liquid.
5. Sharply to press a pedal of a brake of 4-5 times (with an interval between pressing 1–2), and then, leaving a pedal pressed to turn on on 1/2–3/4 turns the valve of release of air. Thus in a liquid following from a hose air vials will be visible. After вытекание liquids from a hose will stop, to wrap densely valve of release of air and to release a brake pedal.
6. To repeat item 3 until allocation of vials from a following liquid completely will not stop. Thus it is necessary to watch level of a brake liquid in a tank and to add a brake liquid in a tank, without supposing большего level decrease 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 a brake liquid.
The prevention

If prorolling of brake system is executed insufficiently carefully by pressing a pedal in the end of its course raised "softness" of a pedal will be felt.
