Brake pedal assembly for a motor vehicle

The brake pedal system for a car has a secondary arm (6) mounted on the same pivot as the pedal (4), but able to turn independently of it. A control lever is attached to this. The pedal and arm are connected by a pin (7) passing through them which fits against a Z-shaped plate (8) welded to the pedal. This cooperates with a stop (10) mounted on a fixed component of the car so that it is deformed to free the pedal in a crash.
