Abstract
The hydraulic brake booster (12) of the present invention comprises a full power hydraulic brake booster (12) that provides false travel during full power operation and improved pedal feel during manual operation. The booster (10) has a housing (24) with a slidable sleeve assembly (60) therein, the assembly (60) housing a sleeve member (98) which is displaced by accumulator fluid pressure against a collet housing (78) and a moveable collet member (79) located about an input member (94). The sleeve member (98) displaces the moveable collet member (79) against a resilient member (77) when the sleeve member (98) is displaced by hydraulic fluid pressure from the accumulator (14). In the absence of hydraulic fluid pressure, the spring member (77) displaces the moveable collet member (79) against the sleeve member (98) so that the moveable collet member (79) is trapped tightly between the collet housing (78) and input member (94) in order to couple the input member ( 94) with the sleeve assembly (60) for conjoint movement in the booster housing bore (26).
