I was looking at it from a one end is worn more than the other.

The pins and slides keep things moving straight. That'* a lot of angle to be on the outter pad only.

Nope, no real reason at all other than it'* something I can do to the car, I can just add checking the pads to the list of things to do come spring time

OK, here'* my guess. If the inner pad was OK, that suggests that the caliper piston was moving back in the bore when the brake was released, but if the pins were bad not allowing the caliper to slide, we would see more wear on the outboard pad. So, if that is correct, the problem was more likely to be pins, than the piston.

I'm thinking that failure to completely release, whether caused by a bad hose, sticking piston or failing booster, should show excessive wear on both the inner and outer pad.

But that'* just guessing. If there is someone on here who does brakes for a living, maybe they will help us out with a more informed analysis.

Oh, and while we are providing free analyses, I'd say (from the condition of the stitching) that the other shoe should be good for at least 6 more months, as long as you change your socks everyday.

I'm certainly not disagreeing. Unfortunately, it'* really hard to tell at this point.

The thing I'm getting at is..it'* not worn evenly across the entire outter pad. Only one end of the pad was wearing. That suggests the other end was not touching the rotor.

When you did the brakes this time, did you pull the pins, then clean and lube them too? If not, I'd suggest that you do that. If you did, how well did they seem to work? I agree with the others that the slide pins would be the #1 suspect. I'd prefer to check and possibly correct the problem, rather than take a wait and see view...but I'm a bit anal about brakes. I also agree with the condition of the other shoe and sock changing.

On my last brake change, I pulled the pins to lube them and found that the factory originals had a dimple in the bushing that kept the pin from coming out easily. In removing them I ended up damaging some of the threads on the pin. I bought replacement ones from AutoZone just to be safe. I did have a little problem with the rubber inserts when I reinstalled the new pin/bushing but I used a little dishwashing soap to lubricate the rubber and was able to get everything back in place. Good luck - It'* not as easy as it should be.
