Brake Disc Thickness Check
- Remove contaminants or corrosion from the brake disc surface.
- Use a micrometer to measure the brake disc thickness at minimum eight points which are 10 mm (0.39 inch) inward from its circumference.
Standard value:
26.0 mm (1.02 inches) < Front (Except RALLIART) >
24.0 mm (0.94 inch) < Front (RALLIART) >
10.0 mm (0.39 inch) < Rear >
Limit:
24.4 mm (0.96 inch) < Front (Except RALLIART) >
22.4 mm (0.88 inch) < Front (RALLIART) >
8.4 mm (0.33 inch) < Rear >
- If the brake disc thickness is worn beyond the limit value at more than one point, replace the brake disc and check its run-out.
