- take off the clothes covered in the fluid, dry them outside the room
and wash.
Service brake system: disc brakes on front wheels; drum brakes on
rear wheels; two separate circuits with the hydraulic drive, coming from
the twin-barrel master cylinder: the one barrel to the front wheel brakes,
the other barrel to the rear wheel brakes.
Emergency brake system is each circuit of the hydraulic drive.
Parking brake system: drum brake mechanism located behind the
transfer case, which affects the rear propeller shaft and has mechanical
drive.
The brake fluid level in tank 14 (see Fig. 9.32) can be checked visually
using marks on the tank housing made of semitransparent plastic.
When the cap is off and the brake linings are new, the fluid level
shall be on the MAX mark. If the brake hydraulic drive works properly,
the reduced level of the tank fluid is associated with worn linings of the
brakes shoes. The fluid level reduced to the MIN mark indirectly indicates
their maximum wear. In this case, control the linings condition, with that
there is no need to add fluid into the tank, as installation of new linings
heightens the fluid level up to the normal.
The brake fluid warning light comes on when the fluid level falls
lower than the MIn mark, which indicates that if the brake shoe linings
are new or partially worn, the system is non-hermetic and the fluid leaks.
In this case add the fluid only after all leaks are eliminated.
ATTENTION! If the vehicle is equipped with ABS and the brake fluid
level is reduced lower than the MIN mark or air enters the system, do
not drive the vehicle and contact a service station, as this failure needs
to be inspected with additional diagnostic equipment.
Bleed the brake system if the vehicle is not equipped with ABS.
Check brake hoses. If cracks appear on the outer side of the hoses,
replace them.
ABS-equipped vehicles have steel pipes. If corrosion appears, replace
them.
Anti-lock Braking system (ABs) prevents the wheels from locking
up while braking, which keeps the initial motion trajectory and minimum
braking distance. however the vehicle braking distance can be increased
when braking on roads with soft surface (gravel, sand, unrolled snow)
compared to lock braking in the same conditions.
