One example I know of actuates the brake calipers in the normal fashion for emergency braking.
The vehicle will stop as quickly and safely as it possibly can under EBCM control.
The electric handbrake shoes ARE NOT used under these conditions.

I cannot see how you could possibly have an electric handbrake in any other way.
It would apply the handbrake too harshly and without modulation control would surely be an accident waiting to happen.
