Air removal from brake system

GENERAL INFORMATION

To delete air from brake system it is necessary, if it was opened in any point or air got to system otherwise.
Before removal of air it is necessary to wipe from dirt and extraneous particles of the location of unions for removal of air and a jellied mouth. If air is removed from all system, it is necessary to begin with a point which is most remote from a tank. If only one wheel cylinder or a support was disconnected, it is enough to remove air from a contour to which possesses the specified element.
In repair trucks air from brake system is removed the special adaptation under pressure. Use of this device here is not described. Here the well-known way consisting in an otvorachivaniye manually of the union of removal of air is described.

PERFORMANCE ORDER
1. Remove a protective cap from the corresponding union of removal of air and put on it a transparent hose.
2. Other end of a hose lower in the capacity filled with a quantity of brake liquid.
3. Ask the assistant to press several times a brake pedal, having pressed it to a floor.
4. Unscrew the union of removal of air on a half of turn during the moment when the pedal is close to a floor. Brake liquid will follow on a transparent hose in a vessel.
5. As soon as the assistant will tell that the pedal is pressed to a floor, close the union and slowly release a pedal.
6. Check and if necessary add liquid in a tank.
7. Repeat the procedure described above until liquid following in capacity, will not contain air vials.
8. The same repeat on other unions in the specified sequence. It is necessary to watch closely liquid level in a tank. Decrease below a certain level can lead it to an air zasasyvaniye in system that will demand its repeated removal.

Some words about brake liquid. It is necessary to apply the brake liquid recommended by Opel firm. Never apply liquid which a long time stood not closed. Brake liquid sucks in moisture.
Brake liquid contains some harmful substances which can harm to a skin covering of the person. At hit of brake liquid on skin immediately wash out this place. If liquid scattered in an eye, it is necessary to address immediately to the doctor. Brake liquid influences destroying on paint and varnish coverings.

REPLACEMENT OF BRAKE LIQUID
(address also to Chapter 1)

At the car of the previous series, i.e. to the middle of 1995 of release, it is necessary to change brake liquid once a year or each 15 000 km of run depending on intensity of operation. New models of the car with disk brakes of back wheels demand replacement of brake liquid once in 2 years. However at these cars liquid level in a tank should be checked each 15 000 km of run.

CHECK OF TIGHTNESS OF BRAKE SYSTEM

For check of tightness of brake system it is necessary for holding under pressure within 10 minutes.
As deduction of a pedal of a brake during specified time represents rather laborious work, there is a special adaptation for pedal pressing.



It is inserted between a pedal of a brake and a seat frame, as is shown in иллюстр. If after specified time the adaptation appears still clamped, it indicates pressure existence in system. If pressure falls, the adaptation also will fall. In this case it is necessary to look for a leak in the system which sign are spots of brake liquid.
