A bicycle disc brake caliper (21) with a detachable cooling system (20) that transfers heat away from the actuating fluid. Basically, the bicycle disc brake caliper (21) has a housing and a piston unit, with a coolant member (24) of the cooling system (20) attached to the housing. 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 the release position, in which the piston unit is spaced from a brake disc (22) mounted to a wheel of a bicycle (17), and a braking position, in which the piston unit engages the brake disc (22) of the bicycle wheel (17). The coolant member (24) has a coolant area for receiving coolant to create a coolant heat sink that transfers heat from the housing. Th ehousing has an actuating passage in fluid communication with the piston unit to move the piston unit via an actuating fluid. In one embodiment, a coolant or water bottle is attached to the coolant member (24) for manually adding coolant thereto. In another embodiment, the coolant member (24) is filled with a high specific heat gel. <IMAGE> |
