Principle of functioning of indicators of wear of frictional overlays of internal brake shoes

1 — the Indicator
2 — the New block
3 — the Worn-out block

4 — the Brake disk


Forward wheels of the car are equipped with disk brake mechanisms of the ventilated type, differing in the increased thermal stability and providing excellent efficiency and stability of braking. Besides, this design possesses property of fast restoration of working functions after moistening.

Back brake mechanisms also have a disk design.

Working disks of brake assemblies fasten outside to naves of the wheels by means of bolts that provides simplicity of their replacement.

The brake shoes which are not containing asbestos are included in the standard package of all models. Internal blocks are equipped with the built-in indicators of wear of frictional slips. Reduction of thickness of a slip to 1.5 mm leads to contact of the indicator with a surface of a brake disk and emergence of the characteristic high-frequency sound warning the driver about need of replacement of blocks.
