Brake Disc Thickness Check
WARNING: This page is about a different car, the 2017 Mitsubishi Mirage. However, it is still accessible from the selected car via links, so may be relevant.
- Remove contaminants or corrosion from the brake disc surface.
- Use a micrometer to measure the brake disc thickness at minimum eight points which are approximately 10 mm (0.39 inch) inward from its circumference.
Standard value: 17.0 mm (0.67 inch)
Limit: 15.4 mm (0.61 inch)
- If the brake disc thickness is worn beyond the limit value at more than one point, replace the brake disc. Then rephase the brake disc so that the minimum brake disc run-out is obtained, or grind the disc while in place on the vehicle so that its run-out is below the limit value.
