Motor car, has brake piston arranged in displacement direction for providing alternative braking force generating facilities to change braking characteristics of wheel brakes based on driving condition of car

摘要

The car has a brake piston (4) movably guided in a main brake cylinder housing (2). The piston is moved under a force application of a force application device (3) and/or under an interposition of a servo device for generating brake pressure in a main brake cylinder (1). The piston is arranged in a displacement direction for providing alternative braking force generating facilities to change braking characteristics of wheel brakes based on a driving condition of the car. The piston is actuated by the application device, so that the brake pressure is generated by actuating areas (14, 15). An independent claim is also included for a method for decelerating a motor car.
