A brake apparatus engages and locks a piston of a hydraulic elevator drive carrying an elevator car or a cable pulley. The brake apparatus includes a pair of opposed pivotally mounted brake arms each carrying a brake lining for engaging the exterior surface of the piston. Each brake lining has a plurality of the vertical grooves formed in a contact surface to define planar sections spaced from a curved support member. As the brake linings are brought into engagement with the piston surface, the compression forces are evenly distributed by the planar sections functioning as springs.
