Abstract
A brake booster with a master cylinder (10) comprises: a primary piston (12) and a secondary piston (14), with the secondary piston (14) being limited in its axial movability by a stop pin (25) being accepted transversely to a longitudinal axis (L) of the master cylinder (10) in a hole (24), and a reservoir (16) for brake fluid, comprising a connection (17) via which the reservoir (16) is connected with the master cylinder (10), with the connection (17) being arranged in the radial extension of the stop pin (25), with the connection (17) comprising a transverse web (28) in its flow cross sectional area which covers the hole 24 at least partially.
