ABSTRACT:
A master cylinder includes a housing with a pair of pistons movable therein to develop fluid pressure in a pair of pressure chambers. One of the pistons carries a seal assembly in order to provide a fast-fill feature. The seal assembly engages a large diameter section during initial braking and separates therefrom after a predetermined fluid pressure level is reached so that the one piston moves relative to a small diameter section to continue fluid pressure buildup during braking.
