Abstract
A dual master cylinder has modular proportioners attached to an outlet from each pressurizing chamber. The master cylinder is shown installed in an X-split vehicle brake system. The master cylinder assembly includes a pressure failure warning device. The arrangement provides a minimum number of leak points, permits the master cylinder and the modular proportioners to be built and tested separately, and enhances serviceability since the modular proportioners can be separately replaced without removing the master cylinder. It also permits the master cylinder to be of a universal type with modular proportioners of various proportioning characteristics used in accordance with the particular vehicle application.
