ABSTRACT:
In a master cylinder and servo booster assembly for a vehicle braking system a mounting plate is connected to the rear end of a vacuum operated servo booster. A tubular extension integral with the mounting plate extends sealably through the movable wall of the booster substantially to relieve the booster housing of braking reaction forces. Circumferentially spaced axially extending slots divide the extension into axially extending arms which are secured to the master cylinder housing at their free ends by the engagement of a radially extending projection on the end of each arm with an annular recess in the outer surface of the rear end of the master cylinder housing. A sleeve integral with the front shell of the booster housing encircles the ends of the arms and holds the arm ends in interlocking engagement with the master cylinder housing. Alternatively, projections on the master cylinder housing and recesses on the ends of the arms may be provided to secure the arms to the master cylinder housing.
