<p>PROBLEM TO BE SOLVED: To provide a brake booster such that the assembly of a reservoir to a master cylinder can immediately prevent a stopper pin from dropping. SOLUTION: This brake booster includes a master cylinder 10 with a primary piston 12 and a secondary piston 14, and a reservoir 16 for brake fluid, with the axial movement of the secondary piston 14 being limited by a stopper pin 25 received in a hole 24 extending transversely to a longitudinal axis L of the master cylinder 10, and with the reservoir 16 being connected to the master cylinder 10 via a connection 17. The connection 17 is arranged in the radial extension of the stopper pin 25 and includes a transverse web 28 in its flow cross sectional area which covers the hole 24 at least partially.</p> |
