ABSTRACT:
A bicycle brake disk caliper apparatus comprises a caliper housing, a piston operatively coupled to the caliper housing so that the piston moves between a brake release position and a brake activating position, a hydraulic inlet for receiving a hydraulic fluid to move the piston, a piston activating space in fluid communication with the hydraulic inlet so that the hydraulic fluid moves the piston from the brake release position to the brake activating position, a cooling member, a cooling inlet in fluid communication with the hydraulic inlet, a heat transfer space in fluid communication with the cooling inlet, and a cooling outlet in fluid communication with the heat transfer space for communicating hydraulic fluid from the heat transfer space so that at least a portion of hydraulic fluid flows only one way from the hydraulic inlet, through the cooling inlet, and through the heat transfer space.
