Brake Rotor/Disc: Testing and Inspection
Rear
Rear Brake Disc Inspection
Runout
1. Raise the rear of the vehicle, and support it with safety stands in the proper locations. Remove the rear wheels.
2. Remove the brake pads.
3. Inspect the brake disc surface for damage and cracks. Clean the disc thoroughly, and remove all rust.
4. Install suitable flat washers (A) and wheel nuts, and tighten the nuts to the specified torque to hold the brake disc securely against the hub.
5. Set up the dial gauge against the brake disc as shown, and measure the runout at 10 mm (0.4 inch) from the outer edge of the disc.
Brake disc runout:
Service limit: 0.10 mm (0.004 inch)
6. If the brake disc is beyond the service limit, refinish the brake disc with an on-car brake lathe. The Kwik-Lathe produced by Kwik-way
Manufacturing Co. and the "Front Brake Disc Lathe" offered by Snap-on Tools Co. are approved for this operation.
Max. refinish limit: 8.0 mm (0.31 inch)
NOTE:
^
If the brake disc is beyond the service limit for refinishing, replace it.
^
A new disc should be refinished if its runout is greater than 0.10 mm (0.004 inch).
Thickness and Parallelism
1. Raise the rear of the vehicle, and support it with safety stands in the proper locations. Remove the rear wheels.
2. Remove the brake pads.
3. Using a micrometer (A), measure disc thickness at eight points, about 45° apart and 10 mm (0.4 inch) in from the outer edge of the disc. Replace
the brake disc if the smallest measurement is less than the max. refinishing limit.
Brake disc thickness:
Standard: 8.0 - 9.1 mm (0.35 - 0.36 inch)
Max. refinishing limit: 8.0 mm (0.31 inch)
Brake disc parallelism: 0.015 mm (0.0006 inch) maximum
NOTE: This is the maximum allowable difference between the thickness measurements.
