My new discs are Squeaky!

Whats the best way to fix this? Do they just need breaking in? Ive heard alcohol. Anything else? They sound like a cat on crack!

Yea i had that problem on my Hayes, most likely its either breaking in or the pads are rubbing. if you have hydraulics, i would search the forum, because i posted a thread earlier on adjusting hydraulics, its really easy to do, but if you have mechanicals, you can adjust the pads based on cable tension

They are XT discs. I just got my bike back from my LBS. My mechanic said he tried and tried to get the rear to quit squeaking. He thought they just needed some braking in. I will ride them a while before doing any adjusting.

I don't know about any other cable actuated discs, but in order to adjust Avids, you don't touch cable tension. Rather, you turn the red knobs which adjust pad position in the caliper.

It's just their way of letting everone know you ride like a maniac. They'll hear you howling down the trail and know to get out of the way in advance.

If the brakes are new, chances are they just need breaking in. Find a section of trail that has a smooth long downhill section. Ride down get some speed and then halfway apply (drag) the rear brake to try to break in the pads.

Or, someone touched the rotors or the pads with oily fingers and contaminated the system. I would take some denatured alcohol and wipe the rotor clean.

If that doesn't solve the problem, you may have to cook your pads. You can bake them at about 250 degrees for 15 mins. Just make sure put some aluminum foil below to catch any dripping from contaminates.

mmmmmmmm tasty. i know the sound, just got a new bike myself.
probably break-in. keep riding and adjust the breaks periodically until (hopefully) it stops. it's getting less and less noisy as i do this.

My rear brake started squeaking on me my last time out. It sounded like I was being chased by a Mothra-sized cricket. I'll try a downhill drag to break them in a little more.

ok, although my rear as fading some. I began to inspect the brake further. I noticed my rear pads are not exactly even. they are just barely off. Could this be causing the squeeling and should I take it back to my LBS and tell him to fix it or let them break in futher more?

My husband's Hayes discs on his Blur sound terrible. I can always hear him coming behind me, and it's more annoying than when a leaf gets stuck in my v-brakes!! I actually try harder to drop him now, so that I can get a break from his howling brakes.

Sounds like his calipers are not properly adjusted. There should be an even amount of distance from the pads to the disk on each side if they are hydraulic. Mine will rub sometimes after I really heat them up on a long downhill runs. But they generally do not make any noise. I have to re-adjust them after reinstalling the wheel each time. Not necessary on the trail if you have a flat. I'll wait until I get home.
