Abstract
Abstract A master cylinder comprising a cylindrical body (1) which points along a main axis (X). The cylindrical body (1) has a free end (11) and an attached end (12) with a piston rod (2) extending axially from the attached end (12). An impact deflector (3) removably mounted on the cylindrical body (1) covers the free end (11). The impact deflector (3) has at least one deflecting surface (D) which is inclined obliquely to the main axis (X).
