I have noticed that for some reason in the winter, my brake pads dont last for anything. The last ride I went on, the pads werent really rubbing, jsut a little bit, but i coudl pick the bike up and spin the wheel and the wheel kept going for 3+ turns. Anyway, I went through the whoel pad, wore them down to the metal in one ride, and my rim had a good amoutn of balck gunk, which was rubber, all over it. Looks like I turned about 7/8 of my pad into powder and glued it to my rim. why is it my pads do this. Ive been through two sets of pads in about 3 rides.
