Abstract
A hydraulic brake assembly () includes a housing () having first and second side-by-side bores (), each defining a respective master cylinder assembly. Each master cylinder assembly includes a master cylinder piston () slidably movable by actuation of a respective brake pedal () to and between an active position and an inactive position. A spool () slidably disposed within a piston bore () of the master cylinder piston () is operable in a first mode to direct hydraulic fluid from a quick-fill chamber () to a master cylinder chamber () at a first pressure upon initial movement of the master cylinder piston () from the inactive position toward the active position. The spool () is operable in a second mode to direct hydraulic fluid from the quick-fill chamber () to a tank () when pressure in the master cylinder chamber () reaches a predefined threshold.
