INSPECTION



Brake pad lining thickness can be checked without removing the pads. When replacing pads, always check the surface of the rotors for scoring or wear. The rotors should be removed for resurfacing or replacement if badly scored. Replace the pads if they have reached the wear limit, are worn unevenly or if the friction material is cracked. If the pads are worn unevenly, the caliper may be frozen or binding.
