ABSTRACT:
A bicycle disc brake assembly is provided with a brake disc support with a pair of floating discs and a bicycle disc brake caliper with three friction pads. The center or intermediate friction pad is a floating friction pad. The bicycle disc brake caliper can be provided with a cooling system that transfers heat away from the actuating fluid. The bicycle disc brake caliper also has a housing with a piston unit. The housing has a frame mounting member sized to be coupled to a portion of a bicycle frame. The piston unit is movably coupled to the housing between a release position, in which the piston unit is spaced from a brake disc mounted to a wheel of a bicycle, and a braking position, in which the piston unit engages the brake disc of the bicycle wheel. The coolant member has a coolant area for receiving coolant to create a coolant heat sink that transfers heat from the housing. The housing can have an actuating passage in fluid communication with the piston unit to move the piston unit via an actuating fluid. Alternatively, a cable instead of actuating fluid can be used to operate the piston unit.
