If you have a manual valve body, I would avoid using first gear for a burnout! If you still have an automatic valve body, you don't have much choice. I would do some research on how to do a burnout with an auto valve body.
No worries about hitting the switch while driving, or going down track. I may activate the solenoid.... but it's not holding any pressure. Even if you inadvertent closed the switch and held it while stopping, you would still have rear brakes.
