Inspection

Inspect Front Brake Disc Thickness

1. 1

   Inspect the brake pads for wear and discoloration.

2. 2

   Inspect the brake disc for damage and cracks.

3. 3

   Remove all rust and contamination from the surface, then measure the disc thickness at 8 points at equal distances (5 mm) from the outer edge of the brake disc.

   Front brake disc thickness

   - 17 inch Standard: 28.0 mm (1.10 in.)

   - 17 inch Service Limit: 26.0 mm (1.02 in.)

   - 18 inch Standard: 30 mm (1.18 in.)

   - 18 inch Service Limit: 28.0 mm (1.10 in.)

   - Deviation: Less than 0.005 mm (0.0002 in.)

   

4. 4

   If wear exceeds the service limit, replace the discs and pads as a set, left and right of the vehicle.

Front Brake Pad Inspection

1. 1

   Check pad wear. Measure the pad thickness and replace it if it is less than the specified value.

   Pad Thickness

   - 17 inch Standard Value: 11.0 mm (0.43 in.)

   - 17 inch Service Limit: 2.0 mm (0.08 in.)

   - 18 inch Standard Value: 10.6 mm (0.42 in.)

   - 18 inch Service Limit: 2.8 mm (0.11 in.)

   

2. 2

   Make sure grease is applied to the sliding contact points, and check the pad and backing plate for damage.

Inspect Front Brake Disc Runout

1. 1

   Position a dial indicator approximately 5 mm (0.2 in) from the outer edge of the brake disc and measure disc runout.

   Brake disc runout Limit: 0.04 mm (0.00157 in.) or less (new)

   

2. 2

   If brake disc runout exceeds the limit, replace the disc, then measure the runout again.

3. 3

   If the runout does not exceed the limit, install the brake disc rotated 180°, then check the brake disc runout again.

4. 4

   If runout cannot be corrected by changing the position of the brake disc, replace the brake disc.
