The brake pedal is equipped with a safety device
which uncouples the brake pedal from the brake
master cylinder in the event of a severe frontal
collision to reduce injuries to the feet of the driver.
As a result, the pressure acting from the brake
master cylinder on the brake pedal is interrupted
and the brake pedal can be pushed to the floor.
The brake pedal is divided into
3 parts: a U-shaped
profile, a latch and a carrier plate within the brake
pedal.
