This reduces the hydraulic pressure that needs to be applied by the master cylinder, which is why the brake pedal sinks a little when the E-brake is activated.
The stability/traction control actuator also applies force to the brake pads directly, but via a different mechanism than the E-brake.

The E83 has drum brakes on hand brake!!! And it's not 15 year old. OK the world continues to improve.
