My brother has a 02 YZ 250 and the other day when we went riding we came back and found out his rear brake roter is bent. is their any way we can bend it back w/o makin it worse? its not really bad but its bad enough to have to do something adout it. buying a new one is too expensive so any help is appreciated.
I straightened mine with a 12" crescent wrench. It was not perfect, but plenty good enough to used until it needed to be replaced. I know it sounds brutal, but there is little to lose, right?
I have heard of the cresent wrench method before. Just put the bike on a center stand, and spin the rear wheel, where you see the wheel slows down or just stops mark that area with a marker and bend till it spins smooth :thumb:
Make sure the rim is straight, it can fool you into thinking the rotor is bent when it's the rim that is actually bent. :yeehaw: :yeehaw: :yeehaw: Aren't those things cool?
I'd be extremely leary of prying on the rotor while attached to the hub, the stress could crack it. Take off the rotor and lay it on a flat area and check it with a straight edge, then make the necessary adjustments in a vise. If you really want it to be perfect take it to a machinist and have them straighten and surface grind it, much cheaper than buying a new one.
