no whats happining is when i step on the footbrake it doesnt work the bracket that holds the rear master cyl flexes when you step on the foot brake the master cyl tweaks and doesnt allow any pressure to reach the rear caliper if you put your hand on the footbrake on the 650 ac watch the master cyl it moves up and away from the frame ive talked to ac about this problem and due to it being a safety issue there going to be making a support bracket for this reason a few guys that i know that have ac 650s already broke the bracket off the frame
