Abstract
The calipers of a brake assembly are sequentially displaced into engagement with the wheel rim of a bicycle at low and high leverage ratios respectively by a force applied through an actuating cable device. A preload spring force resisting displacement of the high leverage caliper is reduced by buckling of a toggle device when the actuating cable begins displacement of the caliper at the high leverage ratio.
