Disc Brakes and Pads

Repair Procedures

Inspection

Check the pads for excessive wear, the discs for runout and wear, and the calipers for fluid leakage.

Front Brake

Inspect Front Brake Disc Thickness

1. 1

   Inspect the brake disc for damage and cracks.

2. 2

   Remove all rust and contaminants from the surface and measure the disc thickness at no fewer than 8 points at equal distances (5 mm) from the outer edge of the brake disc.

   Front brake disc thickness

   - 16 inch Standard: 25 mm (0.98 in.)

   - 16 inch Service Limit: 23 mm (0.90 in.)

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

   - 17 inch Service Limit: 28 mm (1.10 in.)

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

   

3. 3

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

Inspect Front Brake Disc Runout

1. 1

   Position the dial indicator approximately 5 mm (0.20 in.) from the outer edge of the brake disc and measure the disc runout.

   Brake disc runout Limit: 0.040 mm (0.0016 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 is not more than the limit, install the brake disc by rotating it 180°, then check the brake disc runout again.

Rear Brake

Inspect Rear Brake Disc Thickness

1. 1

   Inspect the brake disc for damage and cracks.

2. 2

   Remove all rust and contaminants from the surface and measure the disc thickness at no fewer than 8 points at equal distances (5 mm) from the outer edge of the brake disc.

   Rear brake disc thickness

   Standard: 10 mm (0.39 in.)

   Service Limit: 8.0 mm (0.31 in.)

   Deviation: Less than 0.01 mm (0.0004 in.)

   

3. 3

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

Inspect Rear Brake Disc Runout

1. 1

   Position the dial indicator approximately 5 mm (0.20 in.) from the outer edge of the brake disc and measure the disc runout.

   Brake disc runout Limit: 0.04 mm (0.0016 in) or less (new)

   

2. 2

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

3. 3

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

Inspect Brake Pads

1. 1

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

   Front Brake Disc Thickness / Pad Thickness

   - Standard: 11 mm (0.43 in.)

   - Service Limit: 2.0 mm (0.78 in.)

   Rear Brake Disc Thickness / Pad Thickness

   - Standard: 10 mm (0.3937 in.)

   - Service Limit: 2.0 mm (0.78 in.)

   

2. 2

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