Premature brake pad wear can be a nuisance. The last thing anybody wants is to have to frequently replace their brake pads. Unfortunately, there are many different problems that can lead to this. Because of this, we've put together a list of potential problems to look for when replacing pads. This blog specifically addresses inboard wear, for outboard check out our other blog here.
Inboard pad wear
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
Pad Wear From Floating Caliper Causes
Caliper housing 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
Sliding Caliper Causes
Caliper housing seized due to corrosion of caliper hardware
Inboard pad binding in knuckle due to corrosion
Caliper piston not releasing properly
Fixed Caliper Causes
Inboard piston not releasing (mechanical)
Inboard pad binding on pins in housing
*Seized slides or a sticking inboard brake pad should be checked before thinking about a sticking caliper piston
