The invention relates to a brake system for a vehicle, comprising a cylinder (3), a piston (4) having a closed end (4b) and an open end (4a) and being movably arranged within the cylinder (3), and a further part protruding through the open end (4a) into a cavity of the piston (4), the further part comprising a shaft (6) arranged along a longitudinal axis (5) of the cylinder (3) and a head having a larger diameter than the shaft (6), wherein a resetter for the piston (4) is arranged within the cavity of the piston (4) to allow for a transmission of forces between the head of the further part and the resetter in a direction of the longitudinal axis (5). At least a part of the resetter is elastic, wherein the resetter is in contact with the inner surface of the piston (4) so that the resetter can support a reverse movement of the piston (4) when a braking pressure is released.
