I'm wondering if anyone has hydraulic surge brakes with an electrically actuated "Bleed Solenoid Valve" coming off the trailer master cylinder? My situation causes me to be downward facing with my tow vehicle & trailer prior to backing up my driveway. This causes hydraulic pressure to be already applied prior to backing up & in this state, I cannot release the "Mechanical" reverse lockout lever. I know Champion Trailers sells the Bleed Valves but you have to drill & tap a hole in the master cylinder for the 1/8" NPT return line. I don't like the idea of drilling & taping into a casting. Does anyone have an Attwood tongue on their trailer with option installed? Can I buy a new master cylinder with 2 port holes already installed? Any info, guidance or help would be greatly appreciated. Below is a pic of the type of valve I am referring to.
