Abstract
A wheel cylinder in a brake assembly includes a housing for movably carrying a pair of pistons. An intermediate wall of the housing separates the pair of pistons from each other and cooperates with each piston to substantially form a first chamber facing one of the pistons and a second chamber facing the other piston. An inlet communicates fluid pressure to the chambers via a first path and a second path within the housing. A pressure responsive member is disposed within one of the paths and is biased to a position opening communication through the one path. When the fluid pressure within one of the chambers reaches a predetermined value, the pressure responsive member is movable to restrict fluid communication to the one chamber while the fluid pressure within the other chamber is free to increase in value during actuation of the wheel cylinder.
