WARNING! If one of the brake circuits is broken, pedal travel
is increased and breaking efficiency is decreased. In this case do
not make short-time multiple pedal pushes, instead push the pedal
until maximum efficiency breaking.
If the brake system is broken, it is not permitted to drive it or
to tow it with a tow-rope. In this case use two wheel towing or a
tow truck service.
WARNING! Brake fluid is poisonous. Keep it in a tightly closed
container. While working with it follow these rules:
- avoid any operations as a result of which the liquid can enter
into the mouth cavity;
- do not let the fluid dry out on the skin; wash it off with soap
and warm water;
- flush the spilled fluid with water, air the room;
- remove clothing contaminated with the fluid, dry it outside
the room, and wash it.
WARNING! After a long parking (over 1 hour) in motor vehicles
UAZ-23608, UAZ-23638, UAZ 31638, start going no earlier than
10-15 seconds after starting the engine, so that the vacuum pump
can create the depression in the brake booster comfortable enough
for braking.
Please keep in mind that frequent pushing of the brake pedal
(immediate pedal push after its release, for example, during downhill)
can lower brake efficiency after the 3rd push in comparison with
the 1st and the 2nd pushes.
To ensure efficient breaking do not let engine idle speed reduce
lower than 850 min
The level of brake fluid in tank 3 (see Fig. 9.29) can be
checked visually with the marks on the tank housing made
of semitransparent plastic. When the cap is off and the brake
linings are new, fluid level should be on MAX mark. If the
brake hydraulic drive is in good order, reduced level of the tank
fluid is connected with the wear of the brakes shoes linings.
Reducing of the fluid level to MIN mark indicates its maximum
wear. In this case, control the linings condition as installation
of new linings heightens the fluid level in the tank up to
normal.
The brake fluid warning light comes on when the fluid level
falls lower than MIN mark, which indicates that if the brake shoe
linings are new or partially worn, the system is non-hermetic
.
