Front Brake Disc Inspection

Inspection

3. Brake Pad - Remove

4. Brake Disc Thickness and Parallelism - Inspect

Brake System - Overhaul, Testing & Troubleshooting

  1. Using a micrometer (A), measure the brake disc thickness at eight points, about 45º apart and 10 mm (0.39 in) in from the outer edge of the brake disc. Replace the brake disc if the smallest measurement is less than the maximum refinishing limit.

Brake disc thickness:

Standard: 25.0 mm (0.984 in)
Maximum refinishing limit: 23.0 mm (0.906 in)

Brake disc parallelism*: 0.015 mm (0.00059 in) max.

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

  1. If the brake disc is beyond the service limit for parallelism, refinish the brake disc with a commercially available on-car brake lathe.

    NOTE: If the brake disc is beyond the service limit for refinishing, replace it.

  2. Inspect the brake disc runout.

5. Brake Disc Runout - Inspect

Brake System - Overhaul, Testing & Troubleshooting

  1. Inspect the brake disc to wheel surface for damage and cracks
  2. Clean the brake disc thoroughly, and remove all rust
  3. Install suitable flat washers (A) and the wheel nuts (B)
  4. Tighten the wheel nuts to the specified torque to hold the brake disc securely against the hub
  5. Set up the dial gauge (C) against the brake disc as shown
  6. Measure the runout at 10 mm (0.39 in) from the outer edge of the brake disc.

Brake disc runout:

Service limit: 0.04 mm (0.0016 in)

  1. If the brake disc is beyond the service limit, refinish the brake disc with a commercially available on-car brake lathe.

Maximum refinishing limit: 23.0 mm (0.906 in)

NOTE:

  • If the brake disc is beyond the service limit for refinishing, replace it.
  • If the brake disc is replaced with a new one, check the new disc for runout. If the new disc is out of specification, refinish the disc.

Front Brake Pad Inspection

Inspection

CAUTION

Frequent inhalation of brake pad dust, regardless of material composition, could be hazardous to your health.

  • Avoid breathing dust particles.
  • Never use an air hose or brush to clean brake assemblies. Use an OSHA-approved vacuum cleaner.

1. Vehicle - Lift

2. Front Wheels - Remove

3. Brake Pad - Inspect

Inner pad

Outer pad

Brake System - Overhaul, Testing & Troubleshooting

  1. Check the thickness (A) of the inner pad (B) and the outer pad (C).

    Do not include the thickness of the backing plate.

Brake pad thickness:

Standard: 10.0 mm (0.394 in)
Service limit: 1.6 mm (0.063 in)

  1. If any part of the brake pad thickness is less than the service limit, replace the brake pads as a set.

4. Front Wheels - Install
