brake noise, clicking sound

[kneipperk]

I have been having problems with the front brakes on my 95 tsi awd. it seems like they are overheating after about 20minutes of driving they start to make a clicking sound when coming to a stop at low speeds. at high speeds they seem to work just fine. no shaking, no noise and they are very responsive. seems to just be the front driver. first time i took them apart and replaced the pads, the problem went away for a week or 2 then came back. 2nd time i took it apart i scraped the brakets that hold the pads in with a wire brush and cleaned them up really good since there was build up and it wasnt letting the pads move much. thought that solved the problem but now 1 month later, it started to do the same thing again..... i see that the back side of my rotors are a lot thinner that the other side, is this normal wear and would this cause my brakes to do this? does this seem like the caliper is not releasing enough so it constantly rubs? i have read thru lots of other threads and didnt find very much help. im pretty sure its not a wheel bearing. the metal bracket clips seem to be in good shape and are not making the pads stick. and the dust shield is not bent and not hitting my hub. im thinking its either the caliper or the rotors but not trying to play the guess and check game until i get other opinions... any ideas?

I'd try new rotors first since the back does look alot more worn (mine were like $25 a piece). It might be as you said and a cal is going bad (mine did that before it just locked up one day). Hope it all pans out easy and cheap Wish I had more advice for you GL

The rotor backs always wear more than the fronts since the piston is on that side. Take the calipers off the sliding pins and make sure all rust/junk is off them (sandpaper if necessary) and inside the slide holes. Then put high temp disc bearing grease on the pins and reassemble. It's crucial that the caliper slides easily on those 2 pins (floating caliper).
