    Broke Cardinal Rule

    After my first ride today, I got home and filpped the bike over and without thinking pull the rear brake lever without the rear wheel installed. After installing the rear wheel the brake pads seem to rubbing when I don't pull the rear brake lever. I do I correct this problem? I have hydraulic disc brakes.

    That's always a pain.
    Um... The generic answer is to remove your wheel, and *GENTLY* try to wiggle something down inbetween the pads to push them apart. A flathead screwdriver is usually the tool of choice, but also by the same people who's most used bike-fixing tool is a hammer... My brakes came with little plastic wedges to use in instances like yours, but I imagine if you're very careful to not damage the pads a screwdriver would work.

    You need to get the pistons (pads) pushed back all the way into the caliper, reinstall the wheel, pull the lever a few times and you should be good to go.

    Screwdriver has been the tool of choice for many years on cars and motos and now being used on the world famous MTB brakes.

    since u already have the wheel reinstalled, loosen the caliper bolts, squeeze the lever a few times, with the lever squezed, tighten the bolts in an alternating fashion.....

    If it was a misalignment issue, then yeah. Buuuuut his little cylinder/piston-ey dealios are now too far in because they adjusted to squeeze a rotor that wasn't there... Which means all of the "push them back apart" posts are correct.

    This isn't really a "cardinal rule." In fact, if any readers have never squeezed their brakes with the rotor out, I encourage you to go do it RIGHT NOW. If you can't figure out how to pry apart your pads in the comfort of your own garage, there's no WAY you're going to be able to do it after changing a tire on the trail, in the dark, in the freezing wind. It's not really a big deal at all.
