How To Remove Brake Proportioning Valve?

[Dano77]

The easiest way is also the cheapest. Disconnect both inlets and both outlets. Take a pair of 3/16 or Metric flare unions NOT compression fittings, And connect and bleed system. The end result will be max braking front and rear so you need to add a pressure limiting type bias valve in side the car. Done
