PCT No. PCT/EP92/01779 Sec. 371 Date Mar. 11, 1993 Sec. 102(e) Date Mar. 11, 1993 PCT Filed Aug. 5, 1992 PCT Pub. No. WO93/02901 PCT Pub. Date Feb. 18, 1993.A brake actuator assembly for motor vehicles. A mounting plate (14) formed with a central hole (60) serves for fastening a pneumatic brake pressure booster (22) to the splashboard (10) of a motor vehicle. The brake pressure booster (22) includes a rear housing portion (50) formed with a rearwardly projecting tubular connecting piece (52) which is pushed from the front through the central hole (60) in the mounting plate (14) and through a central recess (70) presented in a stiffening plate (66) which abuts against the mounting plate (60) from the rear. In this manner the brake pressure booster (22) is centered with respect to the mounting plate (14) and the stiffening plate (66). The stiffening plate (66) is formed in one piece with support blocks (68) for a pedal arrangement (20) of the usual kind in motor vehicles. The pedal unit (20) is entirely pre-assembled before the stiffening plate (66) is put together with the mounting plate ( 14) and the brake pressure booster (22), while being fastened to the splashboard at the same time.
