6.2.12.1. Check of a brake disk and components of the brake mechanism

Check whether there is no corrosion, wear and damage on internal walls of the cylinder. If necessary replace the cylinder case. Eliminate the insignificant defects caused by corrosion or foreign particles with grinding of a surface a small emery cloth. Check whether there is no corrosion, wear and damage on the surface of the piston, the directing finger, a boot of the directing finger and a surface of a brake disk. If necessary replace the corresponding component.

Fig. 6.39. Drawing tags on a bolt of a nave and a brake disk


Mark a bolt of a nave of a wheel and a brake disk before removal for the subsequent installation (fig. 6.39).
Turn off a bolt of fastening and remove a brake hose.
Uncover the directing pin and a pin.

Fig. 6.40. Measurement of thickness of a brake disk


By means of a micrometer measure thickness of a brake disk (fig. 6.40).
Standard thickness: 26 mm.
Minimum thickness: 24 mm.
Replace a disk if thickness of a disk is less minimum admissible.
Fix a brake disk on a wheel nave by wheel nuts (in two places or more).

Fig. 6.41. Check of a beating of a disk by means of the indicator


Check a beating the indicator (fig. 6.41).
Measurement point:
– at distance of 10 mm from an external edge of a disk.
Maximum beating: 0,05 mm or less.

ATTENTION
Before carrying out measurement be convinced that the axial side play is equal to 0 mm.

If a beating considerable, find a point of the minimum beating, consistently displacing the provision of installation of a brake disk on a nave on one opening.
Remove a rust or dirt from the surface of contact of a brake disk and a nave of a wheel.
Establish a brake disk and level the tags made before removal.
