ABSTRACT:
A liquid-cooled disc brake for use in a vehicle having a rotatable shaft, at least one rotor fitted to the outer peripheral surface of the shaft, in which the rotor is unrotatable but slightly axially movable with respect to the shaft, a caliper secured to the vehicle body, having a first wall, a second wall positioned opposite to the first wall and a third wall. The caliper is substantially U-shaped in section with its inner peripheral side opening to thereby surround the whole perimeter of the rotor. The second wall of the caliper is made hollow so that the cooling liquid circulates freely through the hollow portion of the second wall. The disc brake further includes means for thrusting against the rotor provided at an inner side of the first wall of the caliper. The thrust means is operated at the time when the brake is performed. The disc brake also has at least one stator provided in the opening portion of the U-shaped caliper, where the stator is unrotatable with respect to the caliper, and the stator is urged by the thrust means against the rotor to thereby perform the brake operation. The stator has therein at least one flow channel through which the cooling liquid circulates. The third wall of the caliper has at least one recessed portion which communicates the one flow channel of the stator with another flow channel thereof while maintaining the intended liquid-sealability inside and outside the flow channel.
