Wound up buying the SRAM brake kit.
Before replacing it a friend and I packed up my bikes and went for a ride. He's new to mtb (but a good road cyclist) and buying a new FS 29r so I thought it would be a good idea for him to experience the opposite end of the spectrum so he would know what he was missing
Threw the bikes in the minivan and headed out!
We were laughing so hard that I don't remember why I wiped out but I bounced off a couple of trees and folded in half like a swiss army knife. At the time I felt my hamstring burn and knew I either pulled or tore it. Still rode out of the woods though. A couple of days later this showed up. It's hard to see but the bruising extends down into the top of the calf as well.
Guess I'll replace that brake now...
