These are from the same caliper. Left is inner pad, right is outer pad.

I installed new shocks this weekend, and I checked the brakes while doing so. All showed normal wear, except this one. These are from the front-left corner. I replaced all pads, rotors, and fluid when I bought this Jeep 3.5 years ago. Additionally, the caliper at this corner was seized, so I put a new one on at that time.

Obviously the clamping force from the caliper isn’t being applied evenly, which points to the caliper not moving on the carrier bolts correctly. Solution is simply to lubricate the bolts, right? Well, mine aren’t quite like that.

Instead of a long bolt with a non-threaded portion that the caliper slides on, it’s a short bolt that bolts into the part that slides. The sliding part is contained within the rubber boot, and neither were seized. On RockAuto, a new bracket can be purchased ($16), and the sliding pins within the boot can be replaced as well ($4).


For the time being, I reassembled it all, reversing the inner/outer pads, and made sure the caliper could move freely. At that moment, I hadn’t looked on RockAuto and seen that the slider pins could be replaced, so I didn’t know that the ones I have could be removed and greased.

Obviously I’ve got to order a new set of front pads, but what else should I do? I don’t like throwing money at problems, but everything at play is cheap. So do I replace it all? Do I just grease the slider pins I’ve got? OR, and this is the reason I’m posting a brake issue on Oppo, is there something else going on here that I’m unaware of?
