ABSTRACT:
In a master cylinder a housing defines a bore for movably receiving a pair of pistons. A pair of seals cooperate with the pair of pistons to define a pair of pressure chambers and a sleeve disposed within the bore fixedly locates the pair of seals within the bore so that when the pair of pistons are moved within the bore, the pair of pistons move relative to the pair of seals to displace fluid within the pressure chambers to respective brake circuits. A bearing member engages the sleeve to fixedly retain the sleeve within the bore and cooperates with one of the pair of pistons to define an auxiliary chamber which is contracted during a brake application to communicate fluid to one of the pair of pressure chambers.
