ABSTRACT:
A disc brake including a hydraulic actuator and a mechanical actuator is disclosed. The hydraulic actuator comprises a piston and the mechanical actuator comprises a push rod adapted to engage said piston through a self adjusting device, said adjusting device including a nut received on a threaded rod associated to said push rod, a thrust bearing capable to rotate said nut relative to said push rod on movement of said piston in a brake applying direction, and a clutch spring adapted to prevent rotation of the nut in the opposite direction. The thrust bearing comprises a cage which cooperates with the piston through a circumferential lost-motion connection adapted to limit rotation of said nut relative to said threaded rod to a predetermined angle on each hydraulic brake application.
