    A question about brake pads

    I added a 180mm rotor to the rear of my bike. It rubs on the pads so bad that it slows down the wheel enough to stop it as soon as I stop pedaling.
    My question is: Should I put the 160mm back on it and see if that is better, or will the pads break in soon?
    I did accidentally use the rear brake when no wheel was in it a while back, but it worked fine with the 160mm rotor afterwards.

    I used this same rotor on the front before and it worked just fine. Now I have a 203mm up front.

    Well there's the problem. I had a IS to 180mm adapter, but it turned out to be for the front post, so I reattached the stock 160mm IS mount and had a 160 to 180 front post mount laying around so I added that. It seemed to work, but I don't think it is affecting how wide the pads are, unless they are still very thick far back.

    Just thought it might be rubbing the caliper ass'y itself and not the pad is all.

    It looks like the caliper may be crooked. Will bring to my LBS soon.

    If your caliper is crooked you don't need to bring the bike to your LBS. Loosen the caliper mounting bolts so the caliper 'floats' and can wiggle a bit. Hold the brake lever and tighten the bolts down by doing a a few turns per side at a time. While the caliper is off use something to pry the brake pads open a bit as well.

    I think I got it worked out. I just had to loosen and tighten the bolts until I found the right position.
    I will bring it in for my brakes to be bled anyway.
