Abstract
A parking brake assembly for an air actuated disc brake includes an operating shaft for amplifying a force supplied by an air actuator and transmitting the force to brake pads. The operating shaft is pivotable about an axis between a rest position at which a braking force is not applied and an actuated position at which the braking force is applied. An abutment surface on the operating shaft is selectively engageable by a complementary latch of the assembly to retain the operating shaft in the actuated position and thereby apply the parking brake. The abutment surface has a helical configuration.
