Abstract:
A method for assembling a vehicle disc brake assembly comprising the steps of:(a) providing a vehicle disc brake including a housing having a bore formed therein, the bore having an annular groove formed in a side wall thereof;(b) providing a brake piston having an outer surface;(c) providing an elastomeric sealing ring having an inner surface adapted to bear on the outer surface of the brake piston during the initial assembly of the brake piston in the bore and thereafter during application of the vehicle brake system;(d) coating the elastomeric sealing ring with a lacquer to improve the sliding properties of the brake piston relative to the sealing ring to assist in the insertion of the brake piston in the bore during the initial assembly process without losing the resetting property of the sealing ring;(e) subsequent to step (d), installing the elastomeric sealing ring in the annular groove of the bore; and(f) installing the brake piston in the bore wherein the outer surface of the brake piston bears on the inner surface of the sealing ring.
