If brake shoes with audio signals of the wear are installed on
the motor vehicle, change the shoes if clanking (tinkling) occurs,
which indicates the shoes are worn down.
Make sure you properly install such shoes. The shoes with
audio signals of the wear are not interchangeable — the left for
right brakes. Install such shoes from the piston side, so that the
wear signal is in the upper part of the shoe (brake). Install the
shoes without signals to the outer parts of both brakes.
To replace the brake shoes, unscrew bolts 16, remove carrier
18 and spring 1.
Check the brake disc. If its surface has deep notches and burrs,
remove it, clean and grind. When the disc wears to a thickness of
20.4 mm, replace it.
Make sure that the crankcase has no leakage.
Check safety caps 5 and boots 8 for damages and proper instal-
lation in seats, replace them if necessary.
Check the outer surface of bushes 10 in the area of boots 8 for
grease and lubricate them with UNIOL 2M/1 TU 38.5901243-92
grease as required.
Move clip 3 until pistons 9 rest the inner surface of crankcase
17. Bypass valve 14 can be opened to ease the fluid displace -
ment from crankcase 17. Close valve 14 as soon as pistons 9
completely sink into the crankcase. Before moving clip 3 uncap
the master cylinder tank and do not let the fluid overflow while
moving the clip.
It is forbidden to recess the pistons with a tire iron as it can
deform guide bush 10 and damage clip 3 and boot 8.
Replace worn brake shoes from both sides of the front axle.
To bring the shoes to the disc press the brake pedal 2–3 times.
Install spring 1, spring carrier 18 and screw bolts 16.
