Abstract

See full text

A disc brake for a motor vehicle, wherein it is possible to displace the actuating piston in the housing both by hydraulic pressure activation of a hydraulic chamber formed in the housing and via a mechanical actuator, wherein the sealing ring is accommodated in an annular groove formed in the housing. Provision is made here for the annular groove to have a groove floor, which runs substantially parallel to the longitudinal axis of the piston, and two groove walls, which adjoin the groove floor, wherein—as seen in the direction of the longitudinal axis of the piston—a first groove wall is directed away from the hydraulic chamber and a second groove wall is directed towards the hydraulic chamber, wherein the first groove wall merges into the groove floor via a rounded or bevelled transition region at a varying distance from the longitudinal axis of the piston.
