ABSTRACT:
A power brake unit for an automotive vehicle comprising a booster utilizing the pressure difference between a vacuum and atmospheric pressure including a vacuum casing composed of a cup shell and a cover shell, and a master cylinder secured to or formed integral with the cup shell. The entire unit is fastened to the splash wall of a vehicle by a fastening means secured to the cup shell adjacent the master cylinder. This fastening arrangement reduces substantially lost travel of the brake pedal due to extension of the vacuum casing in prior art power brake units caused by brake actuating forces and enable employment of lighter weight materials for the power brake unit.
