This is the most simple caliper system ive ever seen.. to remove disassymble the entire caliper, 2 bolts. Yet, its the hardest change of pads ive ever expierenced. After removing those 2 bolts, the rotors rotate, but the calipers dont come off. Theres a sweet lip around the edge of the rotors to keep the pads seated strait. Even if you drian all the fluid from the caliper, the pistons still dont repress so you have to hit the hell out of the caliper with a large heavy object. My tool of choice was a 5lb sledgehammer.
The rear discs are solid, as in NOT vented so thats pretty gehy too.
Overall = i cant wait to do Big Brake kit.
