or the fluid is leaking. In this case, add the fluid only after all
leakages are eliminated.
Check the fluid level in the tank simultaneously with the
alarm level sensor, which can be done by uncapping the tank
(if the ignition is on, the warning light should appear on the
dashboard).
WARNING! If the motor vehicle is equipped with ABS and the
brake fluid level is reduced lower than MIN mark or air enters
the system, contact a service station, as this failure needs to be
inspected with additional diagnostic equipment.
Bleed the brake system if the motor vehicle is not equipped with
ABS.
Check the brakes hoses. If cracks appear on the outer side
of the hoses, replace them.
If brakes pipes have corrosion, replace them.
Anti-lock braking system. Depending on the configuration
motor vehicles can be equipped with the anti-lock braking
system (ABS). ABS prevents the wheels from locking up while
braking, which keeps the initial motion trajectory and minimum
braking distance. However the motor vehicle braking distance
can be increased when breaking on roads with soft surface
(gravel, sand, unrolled snow) compared to lock braking in the
same conditions.
ABS braking starts from the speed of 10 km/h and is
accompanied by slight pulsation of the brake pedal and typical
noise of ABS actuators.

the brake hydraulic drive, it is recommended to contact UAZ
service station to eliminate the problem.
