A brake system for a vehicle in which a pair of brake discs are mounted on two opposed shafts in alignment with one another and pucks are disposed on opposite sides of each of said discs. The pucks between the discs are supported by relatively movable support members, and an adjustment device is disposed between the support members to vary the spacing between the pucks and discs to compensate for wear occurring in the pucks from braking operations. The brakes are operated by a hydraulic actuator which presses the pucks onto the respective discs and urges them toward an abutment, the abutment being either a fixed member or the head of a mechanical brake which can apply a braking force in the direction opposite to the hydraulic actuator, to apply the brakes.
