Calling all Avid Juicy techies

ok, here the situation, rear juicy 5 dragging....

 

new 100% straight rotor - still dragging

new pads, so pistons back in their proper position - still dragging

 

am about to get them re-bled - should that solve it? I've set these brakes many times before and haven't had any issues.

 

as a matter of interest the front rotor moves a little side to side but still doesn't even touch the pads on either side......

 

so what gives?

check your wheels bearings

check your wheels bearings

 

huh?

[AndreZA]

If the rotor is is touching the pads then just move the caliper. I have a small torch that can stand on its end an I place it underneath the caliper. You can then see where and when the disc is touching. Now just move the caliper so that it does not touch anymore.

 

 

[turtlek]

if the rotor is not touching on rotation check that your wheel bearings are well lubed and not rough when spinning

Try a drop of fluid on the pin. Take the pads out first. A mate had this problem with Juicy's at a race and this did the trick.

Dry and rough wheel bearings may or may not make a wheel wobble. However, loose cones will definitely make the disc touch randomly. Loose bearings are easily identified by taking the wheel by the tyre and moving it back and forth laterally. This will produce a clack-clack sensation when the cones are loose. A very observant cyclist will even notice this when pumping the wheel with a frame pump.

 

The OP didn't say whether the touch was constant, intermittent or once per revolution. He also didn't confirm whether or not these pads are the right thickness for the application.

My Juicy 5's does this when I remove the wheel and some idiot (who can that be?) use the brake lever. Serious PT afterwards... should have taken the 7's.

 

Seriously, try to bleed a little fluid off (just a few drops), it helps in my case. Seems the lbs likes to top it up way past with every service. My Zim$500,000,000 worth.

thanks, all fixed - 5 mins at the cycle factory

What was the problem at the end Rock?

[rock]

really just an alignment issue - seems the old spin the wheel, grab the brake and then tighten isn't really the answer.

 

the brake came off another frame and I think thanks to a bit of dirt and grime the bolts/eashers have a bit of a memeory so when you tighten down thaey kind force hemselves back to ther previous position - ok maybe thats a bit of a long shot.
