It has a 7inch rotor now and its now bent. Is it worth it to go to a bigger rotor? Seem's all I need a 8inch rear mount and a rotor. Not exactly sure which rear mount I need for sure though, it seems theres a few different style's. It still ahs the Avid Juicy5's on it.

I'm pretty hard on the rear brake, I rode BMX for ages with only rear brake so I tend to use it more than I probly should. It get's pretty hot a few times to the point you could smell the pad's.
