Inspection

Front Brake Disc Thickness Inspection
  1. Inspect the brake disc for damage and cracks.
  2. Remove all rust and contamination 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 - 15 inch Standard: 23.0 mm (0.90 in) - 15 inch Service limit: 21.4 mm (0.84 in) - 16 inch Standard: 25.0 mm (0.98 in) - 16 inch Service limit: 23.0 mm (0.90 in) - 17 inch Standard: 28.0 mm (1.10 in) - 17 inch Service limit: 26.4 mm (1.04 in) Deviation: Less than 0.005 mm (0.0002 in)
  3. If wear exceeds the service limit, replace the discs and pads as a set, left and right of the vehicle.
  4. Position the dial indicator approximately 5 mm (0.2 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)

  5. If brake disc runout exceeds the limit, replace the disc, then measure the runout again.
  6. If runout cannot be corrected by changing the position of the brake disc, replace the brake disc.
