Disc Brakes and Pads

Repair Procedures

Inspection

Front Brake

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, and measure the disc thickness at a minimum of 8 points spaced equally (5 mm) from the outer edge of the brake disc. Front brake disc thickness - Standard: 18.0 mm (0.7087 in.) Service limit: 16.0 mm (0.6299 in.) Runout: less than 0.005 mm (0.0002 in.)

   

4. 4
   If wear exceeds the limit, replace both the left and right discs and pads.
5. 5
   Check the pad wear. Measure the pad thickness and replace the pad if it is less than the specified value. - Standard: 9.0 mm (0.35 in.) Service limit: 2.0 mm (0.0787 in.)
6. 6
   Make sure grease is applied to the sliding contact points. Check the pad and backing plate for metal damage.

   

7. 7
   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 (0.0016 in.) or less (new)

   

8. 8
   If brake disc runout exceeds the specified limit, replace the disc, then measure runout again.
9. 9
   If the runout does not exceed the specified limit, install the brake disc rotated 180°, then measure the brake disc runout again.
10. 10
    If runout cannot be corrected by changing the brake disc position, replace the brake disc.

Rear Brake

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, and measure the disc thickness at a minimum of 8 points spaced equally (5 mm) from the outer edge of the brake disc. Brake disc thickness - Standard: 10 mm (0.39 in.) - Service limit: 8.4 mm (0.33 in.) - Runout: less than 0.01 mm (0.0004 in.)

   

4. 4
   If wear exceeds the limit, replace both the left and right discs and pads.
5. 5
   Check the pad wear. Measure the pad thickness and replace the pad if it is less than the specified value. Pad thickness - Standard: 10 mm (0.393 in.) - Service limit: 2.0 mm (0.0787 in.)
6. 6
   Make sure grease is applied to the sliding contact points. Check the pad and backing plate for metal damage.
7. 7
   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: 0.05 mm (0.002 in.) or less (new)

   

8. 8
   If brake disc runout exceeds the limit, replace the disc, then measure the runout again.
9. 9
   If runout exceeds the specified limit, reposition the brake disc by turning it 180°, then re-check the brake disc runout.
10. 10
    If runout cannot be corrected by changing the brake disc position, replace the brake disc.
