I have the Canondale F5 with the Avid Juicy 3 brake system fitted to the bike front and rear. The bike is over a year old and hasnt been ridden hard just on the road for communiting in the summer months.
I have a problem with the rear brake whereby you get alot of vibration when the brake is applied. I have tried bleeding the brake and replacing the pads, i have also tried to align the caliper to the disc with the caliper bolts loose, squeezing the brakes and then retightening but the vibration is still there.
When the brake is gradually applied the vibration shakes the bike and isn't really effectiving slowing the bike until you get to the point where the wheel locks up. I have enough power in the brake to easily lock the wheel but i dont have any intermediate braking ability so they are either off or wheel is locked up.
Is anyone able to give me any ideas to what may be causing the problem?
