Abstract
A master cylinder (10) defines a housing (12) with a bore (14) receiving a first piston (32) and a second piston (34). A sleeve (50) disposed within the bore (14) cooperates with a plurality of seals (68, 70, 72) to balance the forces caused by fluid pressure acting against the inside of the sleeve (50) and the outside of the sleeve (50). The sleeve (50) is made from a lightweight plastic material.
