[#4140333]

Bled my avid elixirs today, but they a still a bit sticky and rub. The pad contact is all the way out and I have adjustedbthe alignment via the mounting bolts, but the pads are still rubbing on the discs.

The rear brake caliper was seized in the out position but I managed to move it before the bleed. So what are my next steps?

Assuming I need to get them stripped and cleaned and there isn't an easy fix ?

Take the pads out of the calipers and very carefully pull the brake levers until the pistons are sticking out of the calipers by about 3-5mm.

Put some brake fluid on the tip of a flat bladed screwdriver and use it to put some brake fluid at the junction of the pistons and the caliper body.

Now push the pistons back in slowly and carefully - make sure they remain square to the caliper body.

This should free up the pistons - this is the major cause of your problem. If it doesn't work after 1 go do it again until it does work ๐Ÿ˜†

Have fun!

+1 for JAG, but I'd put the fluid in there with a cotton bud. Use another bud to clean all the crap out of the calliper 1st (use DOT), so none gets onto your pistons

Avids? Just bin/ebay them now otherwise you'll have grief until you do.

Rubbish. I'm sure some people have had bad experiences with them but you'll find that with any brakes.

I got Juicy 7s on my bike from new and planned to replace them. 4 years later they're still there. They've been hammered plenty and never given a moment's grief. Not done any particular maintenance on them either.

Use whichever brake fluid you would put in the reservoir on your brakes - some are Mineral oil and some use the DOT stuff.

Get the right one or you'll damage your brakes!
