HYDRAULIC BRAKE BOOSTER WITH QUICK TAKE-UP AND REDUCED STROKE ABSTRACT OF THE DISCLOSURE The brake booster (12) includes a housing (30) with at least one piston (38) disposed in a bore (32) to separate a pressure chamber (42) from a work chamber (76). The piston (38) engages a valve housing (79) con- taining therein a valve assembly (80) and the valve assembly (80) is connected to an input assembly (72) abutting the other end of the valve housing (79). The piston (38) is disposed within an extension (81) of the valve housing (79) and a seal (87) and spring (89) are disposed between the piston (38) and valve housing (79) so as to enhance initial movement of the piston (38) and provide a quick take-up and fast fill that compensates for fluid losses in the system while maintaining a reduced stroke for brake pedal travel.
