disc brake drag hayes circa 2003
Have older trek fuel circa 2003 w/hayes disc, which I believe to be
hfx mag or hfx 9 but wouldn't bet my life on it. These brakes (front and rear) have always had a little drag on them, which I don't believe is normal and which I would like to fix instead of changing them out to v-brakes or something else. I believe the pistons are all the way into their cylinders; I can't push them back any further. I don't see any wobble in the rotors. It's as though there's not enough clearance between the pads and the rotors. Looking for suggestions. Thanks. |

Pull out the little bleeder plug things from the levers, then push the pistons back again. Be prepared to clean up the brake fluid that dribbles out, or better yet attach a catch bottle to the fitting before you push back the pads. I gotta say-- hydraulic brakes on a bicycle are dumb, but hydraulic brakes on a bike that use glycol fluid are stupendously dumb. If you can't fix the brake rub, see this as an opportunity to fix the problem that Trek gave you, and refit the bike with Avid BB7 brakes. |
