Description

In BMW’s modern chassis, the brake motor is a core component of the electromechanical braking system. When the driver engages the parking brake switch, this motor drives a small internal spindle or “ball screw” mechanism that forces the caliper piston forward. This design not only eliminates the clutter of manual handbrake cables but also allows for advanced safety features like “Auto-Hold,” which keeps the vehicle stopped in traffic without the driver needing to press the brake pedal.
