Squealing sticking hydros!

My hydros need adjusting. The inside calipure (side that doesnt move) is rubbing up against the disc causing the wheel to squeal. How do I fix this?

Generally, both calipers move on hydraulic brakes. Maybe yours is just stuck?

Bleed um. If that doesn't work you may have some seal issues. I would take it to your LBS and have them rebuild the calipers.

Look here.

http://sram.com/_media/techdocs/2008...ual%20web.pdf\

About page 30 or so tells you how to rebuild the caliper. You can use those directions to reset the pistons in their bores. Doing so will tell you if something is damaged and needs replacing. Replace/fix whatever is needed, bleed the systema nd you're good to go. Or, you may just need to push the pistons back in with a flat blade screwdriver and not mess with the full deal. Try that first. Take the wheel out, obviously. Replace. See if that helped reset things. And yes, both sides are supposed to move.

Cue all the folks that are going to say: see! Told you so! Hydros are too much trouble! In 1...2...3...

Moved the whole caliper on the mount and it worked good enough to get me 5th place at todays race. I am just going to bring it into the shop. I dont have a bleed kit or any idea of what to do with one.

Thanks for the help
