A master cylinder includes a housing (30) with a stepped bore (32) receiving a sleeve assembly (50). A pair of pistons (80, 82) are disposed within the stepped bore (32) and one (82) of the pair of pistons defines portions of compensation passages between a reservoir (37) and a pair of pressure chambers (88, 90). The one piston (82) is movable to simultaneously control communication through the compensation passages.
