Jim I re plumbed the system today as per all new sets ups (yes I used bushing to test) The right wheel still locks up under light braking! Pic attached.
I  also checked the original Dist. block and the right side hole is exactly one drill size larger than the center and right side holes! But still locks up. I need to rethink your suggestion on drilling the  Left wheel hole larger so the RF wont lock up. Humm That should allow more fluid to go to the left wheel and allow less fluid to the right thus helping that wheel not lock up! That does make sense so that will be tomorrows project. Tkx Jim F

Jim its worth a try and there is no such thing as too much advice only not enough. I will try that plumbing arrangement my only question is why are all the original systems plumbed like mine and only the replacements plumbed differently as they all use the same distribution block? Tkx Jim

Listen I love you guys and all your advice
but before posting you really should read the previous posts! I have swap'd sides. I have replaced pads, calipers, lines, master cly, distribution block metering valve and flex hoses.
After replacing everything and thinking on this it cant be the metering valve because the system will work properly without it. Its only needed on slippery roads. It cant be the distribution block as all 3 orifices in the front are the same (unless blocked) It cant be a blocked left line pushing more to the right because I ran a new left line and it didn't help. Its not the rear any more since I replaced those cylnds. The only thing that actually makes the pressure work is the master cyl. It is possible the rod is not working properly and effecting the way it moves over both the outlet holes. I may purchase a new entire unit as my booster is older then the rest and that way I can have an entirely new system. I don't care if I now have a lot of good used parts as I can sell them or use them on my Chevelle project. Today a friend of mine who is a retired GM mechanic of 40+ years looked at the project and thought the same thing. In face no matter how you plumb the 3 front holes in the distribution block it will still work with 1 in and 2 out evenly as again all openings are the exact same. The repo set has it plumbed differently then the factory and it works! I will get this it is challenging and interesting too. Jim

Jim It is plumbed exactly as the assembly manual and the picture on the CRG brake restoration page. Charley, I will recheck those bearing but they only have 6K mi on them and there's zero play in the wheel.
I ordered a brake pressure test gauge kit as none of the 3 auto parts suppliers near by had or could get them? Who knew as there on line info says they have them! Im in no hurry I have all winter. I am going to swap out the rotors and see if that helps at all. Tkx. Jim

Dave I did not replace the front lines but I did run a new temporary line to the left front wheel and the right still locked up. A bent line to the right should make the left front lock up yes?
67 RS I was thinking the same thing today. I just have to make a gauge up as I did check all out local suppliers and they have none. Any suggestions on a gauge I can use and plumb in? I am also not sure of total pressures. I read the list on our site here and some pressure go over 1000 psi under braking?  I also did not see any specific gauges on line for sale only ones used in an ABS application.

I appreciate that and I will continue to search out the cause. Tkx for all your help. Jim

I actually have had 2 stop by 1 was a gm mechanic for a dealer for over 40 years the other works on mainly Jap cars and both are stumped. I may change out all the front steel lines and see if that helps. Today I re read all the articles on 1st gen brakes to see if I missed anything. I looked up Ground up 396 Mstr Cyl and Vac booster kits and they are plumbed differently then the picture on the CRG brake page as they have the Metering valve line to the  LF side of the dist. block instead of the front center!  I have mine plumbed exactly like the CRG pic. I have been stumped on complicated things before and I am sure I will resolve this. Even though I am replacing a bunch of newer parts all will be evenly new when Im done replacing the rest. The car is in one of my heated garages for the winter so I have all the time to find the problem.
It really is sort of simple and that is, something is giving me more pressure to the right front wheel or less pressure to the LF wheel. Humm now I wonder what that is, then problem solved!

Today bleed system with new metering valve and right wheel locks up 1st! All front parts are new and so are both rear cylrs. I have done everything to spec and I have gained nothing. I thought I had it after I Installed the 40 yr old metering valve but the rear cyl went out, repaired those and then the RF  front locked up again. Got a new metering valve and now Im back to the beginning where RF locks up on easy braking. I am now at a loss as I have everything to the factory picture and parts.

 This is the picture you guys gave me in the earlier posts and I copied it. What didn't I do that is not exactly like this pic other then those 2 reducing fittings on the MC? Remember I inherited this problem when I purchased the car and have changed out everything to match that factory pic. I was doing Rolls and Bentley restorations many years before I started to again do muscle cars and RR has over 90,000 parts per car and extremely complicated brake systems. Yes Im over 67 years old too! Yes I have way over 40K in this car without my labor and I am never trying to save money always trying to do it right and I thought I was as I have followed everyone on here's advice. Once I get to bleeding the new parts I will report back.

I removed the distribution block when I installed the exact repo and blew it out and it seemed fine but I install the new one. I will know more once I bleed the system with the the new rebuilt metering valve.

Kelly in earlier posts I list that I changed everything and checked the rotors. The metering valve was missing and I install an old one. That's why I am installing a new one today.

Sauron, I agree. It,was all I had as I just wanted to see if the system worked.  Hopefully tomorrow my new meter valve Will be,here as I was not able to cancel the order.

Nope it's mstr cyl to metering valve. Then rear of metering valve to distribution block as per pic in crg factory pic.
