Inner shoe wearing faster than outer?

Inner shoe wearing faster than outer?

Postby ceedj [OP] » September 23rd 2016, 4:02am

Hi gang, just changed my pads today, and noticed the old inner shoes are down to metal while the outers are nearly new. Bad/going bad calipers? I don't really notice anything wrong while driving (like they're stuck), and I'm getting a slight pedal bounce, but I figured that was air, and will bleed them over the weekend. Thoughts?

Thanks!

Not really "stuck" but extremely slow moving; I usually use a c-clamp on the old pad to compress the slider (piston?), and it was much harder to do this time around. Any tips for fixing? Or would it be better to just get some reman calipers? Rubber hoses are fine, and bleeder screws work well; they have the look of a 16 year old caliper - kind of rusty/ brake dust coated but seem to be fine otherwise. I'm all about a little work and even less cash than spending another $50 or so on it, so I'd be ok with fixing.

Thank you! :)

Sorry I missed the post on page two with the same question, and for mixing up terms (piston vs sliders). So if I buy this:

http://shop.advanceautoparts.com/p/carq ... fragment-3

should fix? Could I theoretically do this without taking off the tires again? I was thinking I could do one bolt at a time, slide it back in, tighten, repeat three times. I can afford $4 on a fix like this, thanks!

Greasing the bolts wont do it. The slides need to move in the caliper so when the O rings get crusty and hard they fail like you mentioned. You can buy the slides, O rings and new bolts. IIRC when I bought them it was called a caliper hardware kit. I got them at autozone.

Buying new parts as mentioned works. I did rehab mine. I took the pins and wire wheeled the snot out of them then once they were good and clean. I used a vibrating sander on them. Then greased them real good. One of the four I did replace. It was a little to pitted. I swapped it from the 90 parts van I had.

Mine work fine now. I kinda measure the work by is it easier to drive to get parts or can I get it done faster just rehabbing them than driving there and back. I hate spending money if i dont have to.

Yeah, I figured it was the sleeve too. They actually look fine (they come out with the bolt, so huzzah!), I just didn't know about greasing them, so Ima try that first, should get me through the inspection, and I'll check the wear before the snow flies.

Thank you! :)

Just a quick update, greased all 4 bolts and sleeves, the jumpiness has gone away and the brakes feel like they're stopping more evenly now. Thanks again for the help! :)

Brakes are cheap. At least they are for a Gen I. I keep another set of calipers and pads and all the hardware in the shop. If it's "time for a change" or if some brake is giving be concern, I swap it out with the new, known good brake assembly. Then troubleshoot/rebuild the questionable brake while it's on the bench.

Without taking the wheel off? Never. Always take the wheel off. Inspect things, check things, lube things, clean things, paint things, rotate the tires!


I typed the B word four times and never once spelled it "Break".

Try not to break your brakes.

Trolls take away from productive work, best to ignore them & go about your business.
