PCT No. PCT/FR95/01666 Sec. 371 Date Jan. 16, 1996 Sec. 102(e) Date Jan. 16, 1996 PCT Filed Dec. 13, 1995 PCT Pub. No. WO96/22209 PCT Pub. Date Jul. 25, 1996A master cylinder (12) and pneumatic brake booster (10) assembly for use in a motor vehicle. The pneumatic brake booster (10) has a casing (15) fastened to a wall (16) which separates a cabin (H) from a front compartment (C) of the motor vehicle. The pneumatic brake booster (10) is actuated by control rod (18) having a rear end which is connected to a brake pedal located in the cabin (H). The master cylinder (12) has a body (20) formed with at least one flange (22) for fastening the master cylinder (12) onto the front wall of the casing (15). An aggressive element (26) extends from the body (20) and engages the casing (15) on rotation of the master cylinder (12) in response to a torque being applied to the master cylinder (12). Engagement of the aggressive element (26) with the casing (15) will attenuate the communication of the torque into the control (18).
