Premature wear of the inboard pad is caused when the it is not allowed to release off of the rotor properly after the brake is released. This can easily cause premature wear, and it is a good idea to learn what the potential causes are. Use the following list and images to help diagnose the pad condition.
Floating/Sliding
– Caliper housing seized on slide pins
– Inboard pad binding in bracket due to corrosion
– Inboard pad binding on slide rails due to corrosion or slide rail wear
– Caliper Piston not releasing properly
Fixed
– Inboard piston(s) not releasing properly
– Inboard pad binding on pins or in housing
