ABSTRACT:
A brake assembly having a brake housing which has an annular member enclosing an annular gap of channel-like cross-section open at its radially exterior side is provided with at least one pair of segmental brake shoes. Annular actuating rings are disposed in the gap between the brake shoes and hydraulically actuated members are associated with the actuating rings to move them against the brake shoes and press the brake shoes against the braking surface. The hydraulic actuating members may be L-shaped slidable members which enclose the sealed annular space into which hydraulic fluid is introduced into the groove, a pair of hydraulic cylinders having pistons which move actuating rings associated with the brake shoes or a ring cylinder and ring piston assembly.
