Abstract
A brake system (10) having a master cylinder (14) connected to wheel brakes (24, 26) of a vehicle through remote compensation valves (20, 22). The master cylinder (14) has a two piece housing (66, 84) with a bore (74, 86) therein. First (32) and second (34) pistons are located in the bore (74, 96) by a sleeve and bearing arrangement (98, 82). Return springs (104, 110) in the bore (74, 96) position the first (32) and second (34) piston to define first (106) and second (114) chambers in the master cylinder (14). The two piece housing has first (22) and second (90) flanges that are joined together by hook (94, 94', 94', 94'') and slots (73, 73', 73', 73'') to form a unitary structure and by bolts (47, 47') which further compress seals (102) by joining the first flange (72) to a brake booster (12) to assure that the bore (114) is sealed from the surrounding environment.
