That would be a little tricky to do. Besides needing a fairly powerful solenoid to yank the cable, you would lose the ability to apply them gently (as you would need to do if you were using them in an emergency situation where the hydraulic brakes failed).

The big problem I see is that you would need something like the air brakes on a large truck. They are set up so that they are "on" when they are not pressurized, and "off" when they are pressurized. You would have to add an air compressor and a pneumatic cylinder that is strong enough to pull on the parking brake cable, in addition to the button and wiring. It could be done, but would be pretty expensive, and complicated.
The scary part of that is if it fails while you are driving, it will be the same as making an "e-brake" stop. If you have a manual transmission, just park with it in gear instead of using the handbrake. I don't use my handbrake at all because it can freeze stuck in the winter. |

I'm still pretty green with my engineering skill set, so it's good to hear an alternative solution from another engineer. |
