Abstract
To reduce the manufacturing costs of a vacuum brake booster, there is provided a holding member radially inserted into the control casing of the control piston, the holding member attaching the movable wall (booster piston) to the control casing and at the same time providing an axial stop for the control piston in the release direction of the booster. To reduce the axial length of the brake booster, the holding member is disposed within the air channel leading into the working chamber.
