Understood, and that being the case, with engine running, no applied pedal pressure, trans in NEUTRAL, should be able to push the vehicle by hand - depress the brake pedal, allow it to bleed down, then attempt to push the vehicle - one or more of the brakes should be firmly applied thru leak-past of the RWAL valve(s), preventing any further vehicle movement - that would indicate faulty valving

correct, the vehicle does not move even at the end of the pedal stroke.

I looked a couple different times. I found a lot things some of which need to be thrown in the dumpster. That will be later. I am sorry as I thought I had saved the part. I have no intention on reinstalling the part back on my truck. I wish I could lock up all four wheels. I am going to the salvage yard to get some parts for my vw. perhaps I can find one on a wrecked dodge.
My truck does a similar thing as far as the master cylinder. Two rebuilt and now a new master cylinder and it still goes to the floor when I hold pressure on the peddle. I have bleed the system several times. Good luck Jim

Thanks for your effort Jim. Don't go through too much more trouble trying to find it. I will pull it off my truck and find the right fittings. I will post up my findings.

Thanks All.

ooook. The line size going into and out of the RWAL Valve is 3/16 with a 7/16-24 nut.
