    SERIUS brake problem (hayes hfx 9 DH/FR)

    yes, i know im cross threading but they didnt answer me in "brake time"

    So i was working on my bike with out the rear wheel in, and i lift up my bike and sqeeze the rear brake to stop it, THE WHEEL ISNT EVEN THERE! so i take out my pads and us a flat head screw driver to push the calipers back in and i go to the right one(upside down right) and it starts uzzing brake fluid out from around the caliper!

    What the heck do i do now! besides call my LBS and Hayes, duh (i say call because i prefer to do the work my self)

    Sorry, sounds like you may have to re-bleed the brake line. can't fix that.

    Ur pads got splashed by oil? If they do, they are now contaminated. If not, then they are good.

    something similar happened to me but I didn't have leaking fluid. I did however have trouble with one of the calipers retracting and it had to be sent to hayes because some valve or something turned inside out. Fixed under warranty but hope you don't have that prob too.

    Push the pistons back in. Rebleed the line and it should work. If not just get a piston o-ring kit, replace the rings, then rebleed. They're fine.

    Its true unless you soak your pads in denatured alcohol.

    basically the piston came out too far........push it back in (all it is is a round cylinder with an "O" ring on it - nothing fancy)......then re-bleed....everything will be fine

    uh... maybe because it's good to bleed your brakes every now and then? Haven't heard that one before

    I think the real problem is you got SERIUS instead of XM. Switch and that shoud fix your prob

    Come on guys, I'm being super serial! Why doesn't anybody take me serial? The man-bear-pig is out there!

    Denatured alcohol will not fix contaminated pads. You can clean and burn off some of the DOT fluid, but you will never get all of it. Braking performance WILL still be affected.

    Sounds like you pushed the pistons out too far. Inspect the seals for damage, or excessive wear. Replace if neccesary. Push the pistons back in (NOT WITH A SCREWDRIVER). Do not push the pistons in by the center post either. Use a box-wrench and work it back in. There's a good chance you'll need to rebleed.

    The 9s are pretty poor. Anybody want to buy a pair?

    Excelsior!

    sorry, i guess i stated it wrong, i pushed the right cylinder in, THEN it started leaking. NO LIQUIDS GOT ON THE PADS, they are fine!

    2 day i finished replacing my chain and cassette and i decided to see wat would happen if i tried to put the pads back in and went along like nothing happened. well, it worked, the cylinder dont leak any more but i lost some fluid so i just need to re-bleed, i guess u guys were right.

    Your description was vague at best.
