Abstract

A coupling apparatus has an input piston disposable on a braking input element and an output piston disposable on a brake master cylinder, to which a driver braking force is transferable via the input piston. In a first operating mode, the input piston displaced out of its initial position over a brake application distance less than a first minimum brake application distance, is spaced apart from the output piston. In a second operating mode, the input piston displaced out of its initial position over a brake application distance less than a second minimum brake application distance, is spaced apart from the output piston, and the driver braking force is transferable via the input piston to the output piston.
