Front

1. Loosen the front wheel nuts slightly, then raise the vehicle and support it on safety stands. Remove the front wheels.
2. Remove the brake pads.





3. Using a micrometer, measure disc thickness at eight points, approximately 45° apart and 10 mm (0.4 inch) in from the outer edge of the disc.

Brake Disc Thickness:
Standard: 22.9 - 23.1 mm (0.90 - 0.91 inch) Max.
Refinishing Limit: 21.0 mm (0.83 inch)

NOTE: Replace the brake disc if the smallest measurement is less than the max. refinishing limit.

Brake Disc Parallelism: 0.015 mm (0.0006 inch) max.

NOTE: This is the maximum allowable difference between the thickness measurements.

4. If the disc is beyond the service limit for parallelism, 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.






5. Use wheel nuts and suitable plain washers to hold the disc securely against the hub, then mount a dial indicator 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 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: 21.0 mm (0.83 inch)

NOTE: A new disc should be refinished if its runout is greater than 0.10 mm (0.004 inch).
