This has been talked about before but i have a question.

I have a front 1999 Hayes disc brake and a rear 2002 disc brake.
The front has been silent (with regular cleaning) since the day i got it. The rear has been loud and obnoxious since the day i got it(about a month ago. I have tried all the tricks including soaking in alcohol, sanding, and baking in the oven as well as cleaning the rotor with alcohol. Here is the question.
When you bake your pads what temp and for how long?
When you sand your pads what type of sandpaper do you use?
(Fine or course)

I do the same cleaning procedure to both front and rear at the same time and the front is ALWAYS silent and the rear is ALWAYS loud. Next is new pads but the rears pads are WAY newer than the front and they have never had oil or brake fluid on them.

why don't you try switching out the rear and front pads....see what happens then you will be able to tell if it is the pads or the rotor.....no????

Are you on a hardtail or FS bike? Sometimes a minute bit of play in the rear suspension can be enough to vibrate under braking. Fuels and Sugars had this issue and Trek released a stiffener to help combat it.

Of course if you're on a hard tail, I have no idea other than making sure everything is tightened and torqued properly.

Definitely try switching pads front to back, maybe even rotors. This will also help balance wear.

Intense Uzzi SL... I was thinking about switching the pads maybe that will be my next thing to try. I just gave everything a good cleaning so i will see if it helped first.

Also make sure all your swingarm bolts are tightened down securely and that your rear shock mounts are in good shape. I have an Uzzi DH and the rear brake required me to space the caliper up about 1mm to align with the rotor right. You might check where your pads hit the rotor as well (mine were hitting a little low).
