Title

(EN) Brake booster device for a braking system of a vehicle, and method for manufacturing a brake booster device for a braking system of a vehicle

Abstract

(EN)

A brake booster device for a braking system of a vehicle includes: a booster body to which a brake-boosting force is exertable by an actuator device; a first piston rod component to which the brake-boosting force is at least partially transmittable via a first contact with the booster body, the first piston rod component contacting the booster body at a first contact surface such that the first piston rod component is at least partially adjustable; and a second piston rod component to which the brake-boosting force is at least partially transmittable via a second contact with the booster body, the second piston rod component contacting the booster body at a second contact surface such that the second piston rod component is adjustable together with the first piston rod component.
