Check the pads for excessive wear, discs for run out and wear, and calipers for fluid leakage.
Front brake disc thickness check
- Check the brake pads for wear and fade.
- Check the brake disc for damage and cracks.
- Remove all rust and contamination from the surface, and measure the disc thickness at 8 points, at least, of same distance (5mm) from the brake disc outer circle.
