The new distribution block is exactly the same as the cast one I took out the other day. Interestingly I searched 69 Camaro engine compartment images and in over the 100 I looked at none of them had the metering valve! Yes I know its supposed to be there originally but it made no difference when I had the valve! In fact the front locked up even more! Once I replace the 2 front calipers I will report back.
Yes I did trace all the lines. Jim

Sauron the old metering valve was removed. The problem from the day I bought the car was under some braking conditions the right front brake would lock up. IN the 3 years of ownership and a full re restoration of the car I bought. It has always done that  and it has done it less without the metering valve. I did not install the disc brakes and there's really no way to know if it came with them from the factory because so many thing have been changed. Tomorrow I get the new calipers and then we will see if that helps. Attached is the set up before I installed another engine last yr. Tkx

Kurt yes to your 1st paragraph. I ran a new temporary line to the LF and the RF still locked up. To be clear it only locks up when driving at any speed when you touch the brake pedal a tad more then very light to slow down. I have replaced everything now except the calipers. I did not think I had too as they were brand new when I bought the car 3 years ago. Yes they always locked up but then continued to get worse over the past 3 years. Upon close inspection it definitely appears the right piston moves faster than the left. Yes I have taken both calipers off cleaned the pistons, applied light air pressure and the both work on the bench correctly I now believe, upon close inspection, they are not identical and that's could be the problem. Tomorrow I will order a new set from "groundup" install them and see if that solves the problem as its the only things left that I can think off.. Jim

update: Today I changed out the distribution block and bleed the system. Tested car right side still locks up. I switched lines same ting. I ran new lines, Same thing, right side still locks up? The only thing I can see is the right side has a GM  stamped caliper single piston and the left side has no markings , single piston. Maybe the previous owner bought a mismatched set? Im going to but 2 new front calipers, should they be single piston or double? It is the only thing I have not changed. Any ideas or suggestions? Tkx JIm F

While driving, even at 1 mph if you brake more then just a light touch the right wheel will lock up. I have been down shifting for 3 years and then just use an extremely light touch to stop the car.  Anything more than that the right wheel locks up. This afternoon I just received my distribution block. I will try and install tomorrow. If that does not work I'm at a complete loss as its the only part I did not replace.  Jim

I did everything you guys recommended except test pressures and changed out both hoses and bleed. right side locks up. Removed calipers blew out pistons checked for problems and put right side pads on left and left side on right bleed out system, right side still locks up. Right now everything is new except the distribution block and that's coming tomorrow. Hopefully that will solve the problem but I have my doubts! Jim

Don't need to pump brakes locks up as soon as you touch the brakes a bit over a light push.

I did check the hoses 1st and they looked fine as they are stainless and only a couple years old. I did take them apart!

Ever since I have this car (3yrs) and have re-restored this car almost entirely the RF disc brake locks up. I 1st removed the additional distribution valve someone added when they installed the new power front discs and that worked somewhat better. I have taken everything apart and if I press more then just a bit the RF locks right up. Any ideas? Tkx
