    Just venting

    Do you ever wish brakes weren't so finicky? Took my wheels off tonight. Wiped my rotors with brake cleaner. Removed, sanded, and replaced my pads. Put everything back together again, only to be greeted by the kaching, kaching, kaching of a warped front rotor.

    Grrr....

    I must've put just enough of a warp into it when wiping it down to make it rub.

    Seven-inch rotor. Not much margin for error, I suppose.

    Too late tonight to do anything. Tomorrow I'll try riding the brake down a big hill, to see whether the rotor will straighten itself. Maybe I'll get lucky.

    If not, I'll take a pipe-wrench to it...

    Doubt you warped it wiping it down (unless you are built like the hulk)

    I would suggest pushing the pistons all the way in again and then cycle the brakes a few times to re-center.

    Mechanicals--so no need to push in the pistons.

    I've played with the inner/outer adjustments on the caliper. I can see the disc "wobble" between the pads. I can't dial the pads in close enough to make the pads engage early in the lever travel.

    I've tried removing and reattaching the wheel a few times, to be sure that I did not get it crooked in the dropouts.

    I was only half-kidding about the pipe-wrench. But that's a story for another thread.

    Maybe I was too ham-fisted whilst wiping the rotor down. I did press down a bit to aid in cleaning.

    Today is a new day. I'll get 'er dialed in.

    MTB brakes could be made to have less "finikiness" but then the size and weight would double the the serious whining would start.

    What fun is it to own a mountain bike if your not always working on it? Like owning an old muscle car.


    But yes I agree, I wished disc brakes were less finicky and I wished more people still used V-Brakes.

    If it isn't broken, don't fix it.

    @SteveUK, "it" was broken. I was getting tons of "chatter" when I hit the front brake. Usually a good cleaning and sometimes sanding will fix that. Trust me, I wasn't doing the work for nothing.

    I'll take my slightly finicky discs over my old v-brakes any day.

    +1 - I'd rather have the Whisk of the Disk than the grind of the rim wobbling back and forth.

    Oh, let's not start that argument up again.

    I just want to get in a ride tonight, and true up my rotors.

    Ride comes first!

    Got in a good ride. And the rotor fixed itself after I burned up (er, bedded in) the brakes a bit on a long downhill.

    A good ride, but reminded me that I could really stand to lose a few pounds.

    Rode for an hour. Came back. Helped a friend install a new bottom-bracket on his road bike. It's all good.

    Is the hub nice and snug? Disc issues are sometimes an extension of a bad hub issue.

    Good luck.

    Yes. Hub is fine. All is good now. See my last post.
