kill switch for vehicle brakes

[Toby Mottram]

I am converting a machine to use a computer control. I can kill the engine using an onboard electrical system but that takes 5-7 seconds. I also need to apply the to stop freewheeling.
What is a name and supplier of a component "kill switch" that when 12 V power is disconnected shuts the brakes down ? My searches only seem to find electrical switches.

"spring applied brake"

Engine ? How may HP ? what orientation ? Is it driving a huge inertia component ?

Many lawnmower engines have a friction brake that rubs on the engine magneto/flywheel as soon as the operator lets go of the handle.

To even start the mower it is necessary to squeeze the handle.

Such a system is needed for all ABS systems that can potentially lock the drivers foot pedal out of the loop so to say.
There have been many cases of lost brake pedal function, especially when it comes to some of the unintended acceleration issues.

Hillard has disc brakes of different styles.
Stearns also some disc brakes, and DC coils for the electric motor brakes.
If you have a hydraulic system as part of your machine, you could add an accumulator and some dc valving and use automotive callipers.
