Have a 08 Busa ive had it apart all winter and last year the rear brakes didnt seem like them stopped me all that well so i replaced them this winter...got it all back together and the brake light stays on so i kept adjusting i think its called the rear master cylinder( in pic) and it didnt work so i adjusted the piece on the back side that has the spring on it and it fixed it so my question is if im riding and my brakes dont seem right do i just adjust the rear master cylinder? thanks
