There is nothing you can do to stop it unless you spray some form of lubricant on your pads, you wanna do that?

Didn't think so

hah... complaining about squeeling brakes, i did that once when i first put on my spanish fly pads, going down a huge hill decided to brake near the bottom... suffice to say people were coming out of their houses.

its something you grow to appreciate :twisted: . it inspires me to clean my rims frequently just to keep them noisy... its why i wet my hopes when riding around the CBD. LOUD = POWER!

oh and yeah... sorry i cant help. :wink:

Yeah... It's more a vibration right?

Vibration at the first point of pad contact is both very annoying and hard to get rid of. It's usually due to something being out of alignment or a bolt being loose. The brake mount on the frame may need to be faced with a proper tool.

Check all rotor and caliper mount bolts for proper torque. You could even go a step further and remove the rotor and caliper, clean all surfaces and then reinstall and tighten to the correct torque.

Then try aligning the caliper...

1. Make sure the wheel is properly seated in the dropouts
2. Check the pads to be sure the pistons are pumped out of the piston bore by an even amount.
3. Loosen the caliper alignment bolts just enough to allow horizontal movement with force. This will minimise/prevent the caliper moving when the alignments bolts are tightened. If you do what's in the manual, you'll tear your hair out...
4. Align the caliper centrally over the disc.
5. Tighten the caliper alignment bolts.

I hope this is helpful.

just a matter of natual frequency, some sort of vibration frequency of the disc is matching the pats, or otherway around :roll: anyway, it won't break anything but it makes a very large noise, you can not stop it untill you fully changed the design, thats why it will only occure under certain condition, such as @ a particular range of speed and force applied.

It is just one of those things you have to enjoy like the sound of a razor rock hub or a loud chainguide! You should usally wear them in before hand by doing about 30-40 panic stops down a heaps steep hill! then afterwards they will work fine! :D
