    My Disc Brakes

    Recently my disc brakes have been squeeking a lot. I don't know if this is normal because I just got them, so if anyone could help me with this, that would be great. Also, the back brake retracts really slowly. Might there be a problem with my cables? Maybe something sticky? Thanks in advance for any advice. Btw, my brakes are Avid mechanical disc brakes.

    Lube the cables, check for kinks in the housing. Try re-aligning your calipers with the rotors, switch pads from front to back, and lightly scuff the rotors with emory paper. Any or all of those things should help.

    Jeez, I hope I don't have that problem...I think that could get old real fast... I'm currently switching over to Avid BB7's.

    Is this a common problem with ALL disks or mostly just the Avid Mech's?

    Most if not all of the posts I've read about disk squeals have been the Avid Mech's but most were rain related.

    Avid squeel ALOT when wet. If your rotor isnt wet, I suggest cleaning your pads, either bake them, or file them down. Rub the rotor and the pads down with rubbing alchohol. It sounds like you just have bad cable routing to the rear brake though.

    I have Hayes mech disk brakes and they squealed quite a bit, once I had worn out the original pad and replaced them with a set of Azteks, the squealing was reduced quite a bit.
    I am on my fourth set of Azteks, no significant squealing, try replacing the pads, the factory ones could be inferior.

    I would suggest cleaning the rotors and filing the pads like DjRider said. Alot of times the pads/rotor kind of glazes over and it causes the squeeling.

    my avid bb7s were squealing like mad but i cleaned off the rotors and pads with rubbing alcohol and then rode around for a while and its all better. rubbing alcohol costs like 1.50
    so go get some right now and go riding!

    clean the discs with disc brake cleaner or rubbing alcohol, then use some steel wool or an emery cloth to get any glaze off of the pads, and allow them to rebed into the rotors.. good as new.

    NO BRAKE CLEANER. Use only denatured alcohol.

    Mine only squeal for a very short period when they're damp. Once the rotor gets squeegeed clean, they stop squealing. For what it's worth, my wavy rotors squeal less than the OEM Avid rotors did. They do seem to stop a little better, too. Basically they're just the rotor that comes with the Juicy 7's. I got 'em for $85 for the pair shipped.

    You can get disc brake cleaner especially for the job of well... cleaning your disc brakes. However Hayes recommend using Isopropyl (sp) Alchol to clean their brakes.
    I do think that the problem will probably just be some grit in the pads so sand them down a bit and clean the rotor. And don't feel special, everyone's disc's squeel some time or another

    So does Avid. I've also found that Aztec pads squeel less than the stock Avid pads.

    I may have to look into a set of aftermarket pads once I wear mine down to the point of uselessness.

    Does EBC make HH pads for Avid Mechs? I know on my Honda CBR they almost doubled the braking power...

    EBC makes red, green, and gold pads....the red are the DH compound, and increase the stopping power ALOT. They wear very fast though...

    The Aztec pads are nice, and are cheap....but dont even try them in bad conditions.

    Wear very fast isn't even accurate. I burned through a set in 25 runs (62500 vert ft). Hayes last 4 times that easily.

    I didn't find the power that much better, but it was there for sure.

    I like the stock hayes. Best overall...

    Yeah I did think that was bad haha compared to standard hayes. Never even heard of aztecs, but if I ever see them on sale I will make sure to avoid them.

    Define bad. Because they've worked in everything I've thrown at them, mud, water, sand all the usual elements

    water can mean rain, puddles, road spray, etc. as well. FWIW, my BB7's squeal when I try to apply light pressure, but not when I really clamp down on them. Dampness just exacerbates the problem. It's something I've learned to live with. It's not a huge deal and if they squeal, I just pull a little harder and they shut up.
