As the subject suggests, I'm having a common problem with my Juicy 3's Hydro Disc's on my '07 Giant XTC2. The rear brakes squeal everytime I use them, for quite sometime now, and I'm sick of the loud noise and the vibration that runs right through the bike every time I apply them, even at very low speed. I've searched the web (and these excellent forums) for answers and have tried the following:
Sanding the pads
Cleaning the rotor with isopropel alcohol
Reaplcing the pads
Applying a 'Disc Brake Quiet' product (tacky rubber substance) to the rear of the pads to eliminate vibration.
Tightening the spokes on the wheel and
Moving the caliper/pads further from the axel and the method for thighting the caliper in Whangen's excellent post in this thread (Update me on the Juicy pulsing/stuttering problem) even though its for Juicy 7's.
The bike shop has tried to fix it each time I've taken it in for a service (ie beedling the brakes etc.).
The problem is so easy to reproduce I can do it by walking the bike forwards and applying the brake. So weight (my weight) or the frame are probably not causing the issue. However, its interesting it won't squeal when I move backwards... The rotor is mounted the correct way.
I haven't touched the rotor itself as yet. It may not be true, even though I can't really tell by eye but its probably the only thing left to fiddle with. I suppose I could get a new one next or is it worth swapping it with the front rotor? The rotor is a Avid factory fitted 160mm size.
Any help or assistance is greatly appreciated. Thanks,
