I recently installed an electric parking brake made by E-Stopp on my VS. The actuator housing is mounted in the tunnel and the push button is hidden. I was trying to get away from having the standard VW hump mounted handle. I didn’t really entertain an umbrella though as I wasn’t going for the authentic look at the time. All I really wanted to do was clean the interior up a bit.
The system works flawlessly so far. As @chines1 notes it cannot be engaged while driving. It does, however, stay engaged if it’s set and the motor is started. It could be considered a bit of an anti-theft device I guess.
My only major concern is that now I have no “emergency” brake to grab if things go awry while driving. I suppose I could remember to turn off the ignition and push the button in an emergency but I don’t want to have to learn from experience.
After I bought the system I learned that some in the Hot Rod arena developed this system after using a similar set up from a Prius. I’m not familiar with that system, but I imagine any car with a push button parking brake would have the same results. That said, I’d still go with a purpose built specific device.
