GENERAL INFORMATION

Prevention

It is necessary to carry goggles when pumping brake system. If brake liquid gets to you to eyes, immediately wash out them water, and address to the doctor.


Pumping

Pumping of brake system is necessary for carrying out to remove from it all air which could get to system at removal and installation of hoses, tubes, a support or the main cylinder.

If air got to brake system because of excessive fall of level of brake liquid in a tank or detachments of brake tubes from the main cylinder, to you, possibly, it will be necessary to pump over all four brakes.

If the brake hose or a tube were disconnected only on one wheel, it is necessary to pump over only a support or the working cylinder of this wheel.

If the brake hose was disconnected in a junction located between the main cylinder and any of brakes, it is necessary to pump over that brake to which there was this hose.

PERFORMANCE ORDER
1. Remove residual vacuum from the vacuum amplifier, having several times pressed a brake pedal at the switched-off engine.
2. Remove a cap from a tank of the main cylinder and fill a tank with brake liquid. Establish a cap into place.
Prevention

Constantly watch level of brake liquid in a tank when pumping brakes and add brake liquid if it is necessary in order that air did not get to the main cylinder.


3. You will need the assistant, and also a stock of more freshly brake liquid, the pure plastic container which has been partially filled with brake liquid, a rubber or plastic tube in diameter about 4,76 mm for installation on the valve of production of air and a wrench to open and close the valve.
4. Pumping of brake system is necessary for beginning with the back wheel located on the opposite side from the main cylinder. Turn off the valve of production of air a little, and then twirl it so that it densely closed an opening, but it can be turned off.
5. Put on one end of a tube the valve of production of air and lower the second end of a tube in the container with brake liquid. Leaving air will be appreciable by vials in a tube and in bank. Before passing to other wheel, it is necessary to remove all air from pormozny system of this wheel.
6. Ask the assistant to squeeze out slowly a brake pedal several times for pressure creation in system, and then to detain her in the squeezed-out situation.
7. When the pedal of a brake is squeezed out, open the valve of production of air so that brake liquid began to flow on a hose. Watch the vials leaving the end of a hose, shipped in brake liquid. When the stream of brake liquid will stop some seconds later, close the valve and ask the assistant to release a brake pedal.
8. Repeat points 6 and 7 until brake liquid will not follow from a hose, free from air vials. After that, twirl the valve of production of air and start brake pumping on diagonalno opposite forward wheel, then the second back wheel and finish pumping of a brake of the remained forward wheel. Do not forget to check often level of brake liquid in a tank of the main cylinder.
9. Never use old brake liquid. It contains moisture which leads to corrosion of elements of brake system.
10. Fill a tank of the main cylinder with brake liquid on termination of pumping.
11. Check work of brakes. The pedal should rigid by pressing and not give in. If it is necessary, repeat all operation on pumping of brake system.

Prevention

Do not go by the car if you doubt a condition of brake system.
