ABSTRACT:
The master cylinder (10) comprises a front or first housing part (12) which is generally U-shaped and a second or rear housing part (14) which is also generally U-shaped, the second housing part (14) being received within an end opening of the first housing part (12). The second housing part (14) has an end opening (16) opposite the first housing part (12) through which a first piston (18) is received. The first piston (18) and a second piston (22) are biased by respective resilient mechanisms (20, 24) disposed within a bore (26) defined by the parts (12, 14). Captured between the first and second housing parts (12, 14) are first and second interface members (80, 90) which have seals insert molded thereon. The first and second housing parts (12, 14) are held together by self-threading screws (100) such that a predetermined clamp load is imposed upon the interface members (80, 90). The master cylinder (10) has outlets (34, 36) all of which are oriented longitudinally toward the fron of the master cylinder. A reservoir (40) is captured between a wall member (50) and the interface members (80, 90) and front housing part 12) so that the reservoir (40) remains in place. The master cylinder (10) may be attached by a screw and nut mechanism (17) to the wall member (50).
