A hydraulic motor is mounted on a non-rotating or stationary part of a vehicle and has two opposed pistons in head-to-head arrangement within a single cylinder with open ends, one piston operating in braking operation to press, directly, a friction pad against one flat side of a brake disk fixed coaxially to a rotating part of a wheel, and the other piston operating, through a yoke-like movable member to press another friction pad against the other flat side of the brake disk. The friction pads are held and slidably guided by a part of the hydraulic motor structure, whereby the reaction force due to braking on the friction pads is received and borne by the stationary part. |
