APPEARANCE
- Trace formation on the disc
REASONS
- Deep marks are caused by wear particles that break between the pads and the disc. Foreign residues (asphalt, mud, water) can enter from the outside of the brake system or from friction material with a poor gripping substance.
EFFECTS
- Decreased braking efficiency due to reduced braking ability during braking and normal operation
SOLUTION
- Replace pads and discs.
