Pappy, if you have disc brakes, don't worry about speed of putting the pin back in. (Assuming Actibrake is still on AS). The pump runs for 20 seconds then shuts off. The system holds hydraulic pressure until bled off, then the pump will run for another 20 seconds. If you've replaced the actuator, check by pulling the breakaway pin. If you have electric drum brakes, then heed above posts.
In an emergency, you can cut one of the wires on hydraulic as well to release....or put the pin back in.
