Abstract
A compliant master cylinder includes a primary piston and a secondary piston which are movable to provide fluid pressure to effect wheel braking in a vehicle. In addition, the master cylinder includes a compliant assembly which supplies conventional pedal feel and travel characteristics when the primary and secondary pistons are substantially immovable due to isolation the master cylinder from the wheel brakes. The compliant assembly includes a push rod piston that is movable against a selected amount of fluid pressure and spring force while the primary piston remains stationary. The fluid force is supplied by controlling the flow of fluid from behind the push rod piston through a flow restrictive orifice to a conventional fluid reservoir on the master cylinder assembly. The compliant master cylinder assembly is operable to provide fluid braking pressure through movement of the primary and secondary pistons by mechanical contact between the primary piston and the push rod piston after a sufficient amount of actuation.
