Hydroboost bypass

I tow a 1999 Ford F-250 diesel behind my Motorhome. It appears that when the tires turn while being towed there is back pressure creating a leak at the Hydroboost master cylnder. I would like to put a manual valve where the power steering pressure hose connects to the short metal line on the master cylender that would allow me to open the pressure line to the return line on the master to the power steering pump. Can you assist me with line size connections and a possible valve salection? Do you see any problem with this other than forgetting to switch the valve when I am ready to drive? I would still have power breaks, I think.

Hi Tevman,

That's gonna be a tough one to answer. Are you using some kind of setup to actuate the brakes on your truck while it's being towed?

Towing Configuration

I probably should but am not using a suplamental braking system at this time. My thought is that if I can relieve the pressure from only the power steering pressure hose back to one of the low pressure return hoses it should not affect the brake side of the Hydroboost. Is this a bad assumption?
