Having swapped my tyres over, I am having real difficulty setting my brakes back up. I have Dawes Diamond folder with canitiliver brakes. I cannot seem to get them set so they don't rub and it is driving me mental with annoyance. I have tried in vain to find a SIMPLE guide online that makes sense. Can anyone point me to or provide a REAL simple set-by-step guide on how to set these brakes up from scratch?
