I replaced my rear pads about a month ago, which at the time was odd because i had just replaced them less than a year before, but i didn't really think anything of it at the time, but now the rear right on is already worn down. i replaced them this morning and the left one looked fine. now the inside pad on the right side was worn down more then the outside pad and it was worn down a lot more on one half of the pad than the other. so i was thinking that maybe this would imply that one of the caliper pins was sticking and holding it down since it seems that a bad piston would cause the pad to wear down evenly. one of the caliper pins felt a little stiff so i took all four of them out and lubed them up. Also when I was changing the pads on the caliper in question the piston was really hard to screw in but the further in it got the easier it was. So for now i am just going to drive for a couple of days and then i can see how easily the back wheels turn when of the ground, but i doubt ther pins were the problem. I read some of the other posts on brake problems and I was wondering if bleeding or changin the brake fluid would help at all in this situation.
Any brake experts out there got any ideas where i should look for a problem? i don't want to drop the $100+ for a new caliper if that is not even the problem. also is it possible to get a rebuild kit for calipers?
