Rear Brake Question

[Cruiser804]

Ok, I recently did a rear axle service and installed new bearings. I noticed that the inner surface of both rotors was worn more than the outer. I have read a couple old posts the mention lubing the slider pins, do you think this sounds like it may have been caused by the pins sticking.

Also, I could be imaginig this but I think I am hearing the pads dragging on the rotors, like the sound of a lathe. I looked through the inspection opening and it looks like the pads are sitting right on the rotor. Didn't see anything in the FSM about compressing the calipers before puting them back on the rotor. BTW nothing seems to be heating up. I might just be f-ing paranoid. I don't feel any drag and the p-brake is very loose so I don't that is making the "sound".

I had a sound like that after replacing my rear pads. My “clips” that the pads sit in were shot. Is that what you mean by pins? Ordered a fit kit from CDan pulled the pads back out replaced all the clips and the lathe sound hasn’t returned. Without the new clips the pads would not release from the rotors plus the clips were bent and scraping the rotors making the lathe sound. FSM calls them pad support plates. I put the anti-squeal shim on the outer pad.

Ahh, I'll try that. Maybe the calipers released/extended some when I removed them. Hell I might as well, funny how one thing leads to another.

The slider pins are long "bolts" that are on the inner top side of the calipers. There is a post here somewhere by Raven Tai that explains their purpose.

hmm, I hope I simply contaminated my pads with oil vs. any of this when I opened up the axle last night. I have a bit of pull to the right...*sigh*

I went out and swaped the rotors from one side to the other, thinking I may have reversed them when I did the axle job. I think I did. Once I changed them the p-brake adjusted better and the noise went away.
