    Hi all, i have a 2008 Specialized Rockhopper with discs on front and rear, the front one as pressure is applied brakes ok, then the handle slowly keeps depressing (but keeps braking ok). When it is released it goes back to the normal position, it almost seems like the hydraulic fluid may be leaking back inyo a resevoir of sorts, my knowledge of disc brakes is zero, any tips very welcome indeed.

    Paul.

    If you’re saying the brake lever is spongy you’ll probably need to bleed the brake. You may want to replace the fluid totally if its a year or more old too.

    Check out your break manufactorers website. That will usually have good in detail tutorials . Also , when you buy the bike , you get alot of manuals for every thing so might be there too.

    I meant to say that the proceedure is the same for all Avid Juicy brakes, Juicy 7’s are being used in the video..

    That’s the boys I was on about and a decent price for what ya getting a lot cheaper than the avid make defenitly worth buying when ya think a lbs will charge about £20

    Cheers Paul.
