Mine! Avid Juicy 7, tried organic pads and regular. The brake and rotors are about 3 years old. They get real noisy toward the bottom of trails like Deer Creek, Chimney Gulch, Mt. Falcon, etc... when they heat up. Are my rotors too old? Are avid pads known for this? Has all the PBR made me too fat for my brakes? The problem has become worse this year, even with replacement pads.

The one upside is that the organics and the other pads make two different tones so I can harmonize when I come down the hill, having organic in the front and the other ones in the back.

Juicy 7 here sound like a dieing ostrage when hot. Not to mention this year am getting a nice vibration to go along with it. I have tried everyting aswell. Maby time for an upgrade.

What rotor size are you using?

My wife runs Avid Jucy 7" front and rear. No sound unless wet.

I like to think that my Juicy 5s help to avoid trail conflict by warning other trail users of my approach well in advance.

Mine can be quieted down somewhat by chamfering the pads and shimming the calipers away from the axles a little. I have also found that Hayes rotors work a little better than the wavy Avid rotors.

Do a search on the brake forum for that Juicy squeal. Not all of them do it but certain frame/brake combos will. Avid makes a solid rotor that usually takes care of it. Your LBS can order it for you.

yetirich - in each caliper run 1 organic pad and 1 metallic pad. Works just as good and no noise. You could go all organic pads for no noise as well but it won't work as well.

Avid BB7's. Many combos of rotors and pads (though I didn't go the organic pad route yet), plus a ton of adjustments. What worked for me:

Stop the vibration - Pull the pads, put a dab of HIGH TEMP grease on the backside, between the pad and caliper - NOT THE BRAKE SURFACE. Or, as an experiment, put a single thin strip of electrical tape on the back of each pad. Readjust. Enjoy sneaking up on people again. Or, get some vehicle Disc Brake quiet that is applied to the non-brake surface of the pad and use that to stop the vibration.

Every time I've had issues with noisy avid's it's been due to small alignment issues. Those fancy dished washers make it easy for them to get slightly off vertical alignment (camber, tilt, whatever)..

Can I recommend a hollow carbon monocoque frame like the Ibis Mojo to go with them, then frequency of the squeal resonates through the frame which acts like an amplifier much like an acoustic guitar. Wonderful sounds and it feels like the bike is a tuning fork when you are riding.

Juicy 5's here and yes I do not have to warn hikers, or anything else for that matter, that I am approaching. I think the vibration in addition to the sound will alert anything within one square mile.

PS - Thank you OP for making me laugh this morning. I miss funny posts rather than these (I had a run in with a hiker/someone didn't yield to me/downhillers are going to kill somebody/etc... posts).

The rear triangle of my Trek Remedy and Session both amplify brake vibrations. It does feel nice, little vibro-massage action :D
