Abstract
A brake booster includes a valve member which is operable to communicate fluid pressure to a pressure chamber for generating a power assist during braking. The brake booster provides an auxiliary chamber to trap fluid pressure leakage past the valve member. An input member is operable during braking to initially vent the auxiliary chamber and thereafter to control operation of the valve member.
