<p>In a pneumatically-operated booster for vehicle braking systems of the kind in which a wall (7) is movable in a booster housing (1) when subjected to pressure differential in order to augment a brake-applying force from a pedal which, in turn, is applied to a master cylinder, and at least one tie-rod (20) extends through the movable wall (7) and the booster housing in order to carry the master cylinder from a bulk head of a vehicle, the tie-rod (20) is adapted to collapse when subjected to a compressive force in an axial direction. <IMAGE></p> |
