The test drive is complete and I am happy. I am absolutely amazed. The brakes are so smooth and quiet. I removed the pressure pin on the pressure regulator for the rear lines, so they get more pressure, but I left the regulator spring and piston in there to give the rear brakes better feathering ability. It provides a tiny bit of softness below ~200 psi. That is the stock knee point for the regulator. The rears will lock just before the front on blacktop, and all 4 will lock at about the same time on gravel.

My reason for wanting more rear brake pressure is payload related. This truck carries a lot of weight on the rear axle, and that weight does not transfer to the front when braking. If empty braking is balanced, then loaded braking will be way off. The truck weighs almost 3x its own weight when loaded, so a little rear bias when empty is fine with me if it means stopping when loaded. Skidding the front tires and not having rear brakes is not cool when you weigh 13k.
