Hmm.
the limited use I've had with race cars always used a hydraulic line lock... a solenoid that locked the brake fluid after you pumped up the pedal...
hit the button, and whoosh off you go.

You wouldn't use this for a park brake because the hydraulic pressure won't stay up once the engine is off.
