    Squeaky brakes

    Anybody have any suggestions for squeaky disc brakes? Brakes seem to be adjusted correctly, and I did scuff the rotor with sandpaper. Any other suggestions, or is this an indication I need new pads?

    THAT I haven't done, and didn't even think about it until you just posted this. Just clean with alcohol, yes?

    The pads are about 1/16" thick.

    Scuff your pads not the rotor. Your pads are probably glazed. Sand you pads and clean the rotor with some brake cleaning spray. Just don't get it on your wheels or frame it may eat the paint or anodizing!

    Any chance you have Avid brakes? If so, throw them out.

    Can I use bearing grease instead?

    My brakes in general have a small squeak. In the last couple rides however, it's been rather annoying..

    A long time ago, but my girlfriend said it made her feel cheap, so we went back to Missionary.

    given our dry climate I would advise against it. the sand and grit that it will attract will defeat the intended purpous.

    all the brakes have their own set of problems, ----I run the advids and there are good.--( I have them on 3 bikes with no noise )
    I will glass bead my rotors and the pads to de glaze them , then they seat in and are fine .

    I have found the advid organic pad with the aluminum backing works the best for me , along with the clean sweep 3 rotor.------( the cheep aftermarket pads do not work at all ---you will play hell to try and make them quiet )

    I run an 8" ft and a 7" rear , ---things work really well , once I get my pads burnished in they will run silent untill they are gone .

    I've heard that the organic pads help with the squeaking. But you have to replace them more frequently.

    I have not noticed hardly any difference in wear ( ----of course I could not get the metalic or cermic pads in any of the brake brands to ever shut up , so I never ran them out -------and they were grabby and screwed with my technical slow speed balance and ridability.
    ( as almost all the cermic metal pads do on all the brakes )

    Once you get used to the smooth progressive feel of the organic pad , and their silent operation you will not ever go back.

    I also see so many guys out here with way way to small of brakes on the bikes , -------this of course will overheat the things quickly ,

    there are so many things to really getting brakes dialed in on a bike , ---the correct 5.1 dot fluid ( for avid ) really gets rid of heat better and will withstand more heat.
    Getting the brakes blead correctly ,
    the correct alignment , the correct clearance on each side of pad.
    Getting the new pad burnished into the rotor .

    any of the brakes on the market all need to be dialed in and worked with to get them working correctly.

    Are your Avid's squeaky or is it a howl that sounds like a honking goose and vibrates the whole frame (and seat post)? If it's the howling, then your frame is resonanting with the caliper vibration. I had this problem every since I got my bike early this summer and the cheapest fix I found was to dampen the vibration on the frame by wrapping an old tube around part of the frame near the offending rear caliper and zip tying it in place. Worked like a charm and now my Avid's are completely silent and it didn't cost me anything.

    Ahh, that would be the infamous Avid turkey gobble. For about 2 weeks, my favorite thing to do on long rides was come up with new ways to describe that sound. My best one was: It sounds like a hillbilly raping a cow.

    How many cows did you have to rape to refine the sound ?

    I have a 6 inch rotor on the back and 7 inch on the front. In wet weather the two brakes squeal in a minor chord that sounds just like a train.

    Change to organic pads. Problem solved.

    Metallic pads might last longer, but they are prone to making lots of noise on ANY brand of brakeset. Plus organic pads just "feel" better.

    Thx...Doug

    Lightly countersink the holes in the rotor, just enough to chamfer the sharp edges. You don't even need to use a drill; just twist the countersink bit with your fingers using light pressure. Do both sides. I've used this trick on three sets of brakes and it has reduced or eliminated brake noises that weren't cured by the usual fixes (cleaning, adjusting, etc.).

    Now that's one tip I have yet to see or try....too bad....since I got rid of my J7's for SLX's....I've had no Turkey on my ride.
