Front Brake Disc Inspection

Runout
1. Loosen the front wheel nuts slightly. Raise the
vehicle, and support it with safety stands in the
proper locations (see page 1-15). Remove the front
wheels.
2. Remove the brake pads (see page 19-12).
3. Inspect the disc surface for damage and cracks.
Clean the brake disc thoroughly and remove all rust.
4. Use wheel nuts and suitable flat washers (A) to
hold the disc securely against the hub, then mount
a dial indicator as shown, and measure the runout
at 10 mm (0.4 in.) from the outer edge of the disc.
Brake Disc Runout:
Service Limit: 0.10 mm (0.004 in.)

5. 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: 26.0 mm (1.02 in.)
NOTE:
• If the brake disc is beyond the service limit for
refinishing, replace it (see step 7 on page 18-12).
• A new disc should be refinished if its runout is
greater than 0.10 mm (0.004 in.).

Thickness and Parallelism
1. Loosen the front wheel nuts slightly. Raise the
vehicle, and support it with safety stands in the
proper locations (see page 1-15). Remove the front
wheels.
2. Remove the brake pads (see page 19-12).
3. Using a micrometer, measure brake disc thickness
at eight points, approximately 45° apart and 10 mm
(0.4 in.) in from the outer edge of the brake disc.
Replace the brake disc if the smallest measurement
is less than the max. refinishing limit.
Brake Disc Thickness:
Standard: 27.9 28.1 mm (1.10 1.11 in.)
Max. Refinishing Limit: 26.0 mm (1.02 in.)
Brake Disc Parallelism:
0.015 mm (0.0006 in.) max.
NOTE: This is the maximum allowable difference
between the thickness measurements.
10 mm (0.4 in.)
4. If the brake 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.
NOTE: If the brake disc is beyond the service limit
for refinishing, replace it (see step 7 on page 18-12).
