1. Remove the brake drum (see the Section Removal, installation and check of a condition of the brake drum).
|
2. Measure the residual thickness of frictional overlays of brake boots.
|
3. At wear of slips below extreme admissible value (1.0 mm) replace boots assembled with drums.
|
In order to avoid loss by the car of course stability during braking, replacement of components of brake mechanisms has to be made for both assemblies of one axis in a set. |
4. At identification of a noticeable difference in the residual thickness of blocks from the left and right side of the car check serviceability of functioning of wheel cylinders and estimate a condition of working surfaces of their pistons.
