Thickness and Parallelism
-
-
Remove the rear wheels.
-
-
Using a micrometer, measure the brake disc or the brake disc/drum thickness at eight points, about 45 ° apart and 10 mm (0.39 in.) in from the outer edge of the brake disc or brake disc/drum. Replace the brake disc or the brake disc/drum if the smallest measurement is less than the max. refinishing limit.
|
Brake disc or the brake disc/drum thickness:
|
|
|
Standard:
|
8.9−9.1 mm (0.35−0.36 in.)
|
|
|
Max. refinishing limit:
|
8.0 mm (0.31 in.)
|
|
Brake disc or the brake disc/drum parallelism:
|
|
|
0.015 mm (0.0006 in.) max.
|
NOTE: This is the maximum allowable difference between the thickness measurements.
-
If the brake disc or the brake disc/drum is beyond the service limit for parallelism, refinish the brake disc or the brake disc/drum with a commercially available on-car brake lathe.
-
Clean the mating surfaces of the brake disc or the brake disc/drum and the inside of the wheel, then install the rear wheels.
