Was in lookin at my brakes and on the left rear the outside pad was worn rite out and the inside pad was in perfect shape, would this be a cause by a bad caliper?
An excessivly worn outside pad is caused by the slides hanging up. An excessively worn inside pad is caused by a caliper piston sticking/brake hose gone bad. Use synthetic grease and dont over grease the slides. I use Silglyde at the shop i work at and it does an excellent job.
