Abstract

A cylinder assembly for an hydraulic actuator for vehicle disc brakes has an annular resilient disc to prevent penetration of dust and moisture into the cylinder, and corrosion is prevented by the presence of a ring (made of a material more electronegative than that of the piston) disposed on the piston in the zone where the inner edge of the resilient disc is clamped. In Fig. 2 a resilient disc 6 is secured at 7 to the cylinder 2 and is clamped at 8 in a groove in the periphery of the piston 10. The corrosion-preventing material comprises a zinc ring 9 clamped between the resilient disc 6 and a collar on the piston. This prevents electrochemical attack on the surface of the piston.
