Abstract
A brake-pressure modulation device in which a hydraulic unit, fitted with solenoid valves, with return pumps, accumulators and dampers of an anti-lock brake system also has a tandem brake master cylinder. The hydraulic unit has a housing with a standard location hole, into which four lip seals identical at least in their outside diameters are inserted. The lip seals hold a primary and a secondary piston of the tandem brake master cylinder. The use of four lip seals with the same outside diameter makes it possible to use the same housing with the standard location hole for different types of vehicle, even when the piston diameter and the operating stroke are changed.
