    Please HELP with HFX-9 !piston problem

    HI everyone. I am from Ukraine and we do not have a Hayes service centers here.
    I just bought the set of new HFX-9 hydro .
    The rear brake is fine. But I have problems with the front one.
    1- the pad on the outer part of caliper moves to much ( the outer piston vent out of it’s place while the bleeding process, spilling the fluid!!!) . the inner piston doesn’t move to much while pushing the lever!
    2- The outer pad is wet at the places it contacts the piston !!!
    3- Is it the problem with the piston seal ??? or anything can be done???
    4- The inner piston moves very little . The outside one too much and it’s wet !!! Its a new set of brakes!

    Hope to here a helpful reply. Thank you in advance !
    Alexey

    That's why I ditched them before my first ride on the new bike! Try to get rid of them, and get some maguras. I mean, honestly, read the reviews! Try to contach Hayes if you have the warranty.

    I'm sorry that I don't have the answer, but don't give up on the Hayes. I have them on 4 of my bikes, and soon my 5th.

    While many have had good luck with Hopes, I've spent many times beside the trails while friends struggle with theirs (locking up when they get hot on closed versions).

    Email Hayes.

    On their website they have an email address you can send technical issues to. You can buy piston rebuild kits for pretty cheap, but since they are new hayes will probably warranty the whole thing.
    Don't get rid of them though. Im not a huge fan of the HFX-9, but hayes brakes will perform as well as any brake on the market if you ask me. Sometimes fixing them sucks, but thats the case with any hydrolic disc brake system.
