Abstract
The piston seal of the master brake cylinder has a rubber ring (42) with outer convex profile to run over the cylinder wall. The inner edge of the seal has a flexible lip (54) with the lip resting against the leading edge of the drive piston, so that a small amount of movement closes the hydraulic path across the piston. The inner lip is less prone to grit damage and operates effectively even with short sharp brake movements. The pumping action of the short brake strokes is avoided so that braking control is maintained.
