A bake piston, which is arranged on a brake caliper of a disc brake of a vehicle, has a first and a second tubular piston body portion which are connected together at a first axial end of the brake piston via an annular end wall. The second piston body portion forms a receptacle in which a spindle nut of a spindle drive is accommodated so as to be axially displaceable and not rotatable relative to the brake piston, and receives a drive spindle. The first piston body portion has a radially inwardly directed floor region. The end wall is axially stepped towards the outside and has a radially outer portion and a radially inner portion which each have an end face pointing axially away from the brake piston, wherein the end face of the radially inner portion is axially offset relative to the end face of the radially outer portion in the direction towards the second axial end of the brake piston.
