Abstract
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) abuts a valve housing (79) containing 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) and valve housing (79) are joined by connector (73) which permits limited movement of the piston (38) relative to the valve housing (79) before coupling the piston (38) and valve housing (79) together for joint movement.
