Took her out today around the property and it seems the RF is locking up again except I need to brake harder to do that. I think it may be the old metering valve I installed. I did clean it up and blow it out and it seems to work with 35lbs of air pressure. Your thoughts?

Sauron327 Tkx the other cyl is new. Not much stock on this car in many years. That's why I bought and built it the way I wanted, though I did use all GM parts that were available in 69. I built one similar in 1970 with same side exhaust. If it was original id keep it that way. Tkx

Ok up date! Rear Right cyl. leaking. Replaced and cleaned. Brake shoes adjust internally there is NO seal, probably because its a 70 or 71 Nova rear! Who knew? I ran the serial number on the axel. Cleaned both sides. Adjusted by putting drum on and off using adjuster. Car stops perfectly now! YEA! Tkx for all your advice.

For the record here is my 400hp camaro

It appears they adjust with the drum off as there is no opening on the rear to adjust?

Yes I read Johns article and several more. Like I stated I inherited this problem and trying to make it right. The only item I can see that is not original type equipment is the metering valve. In all the photos, manuals and parts books I have read there are 3 choices, The 71-77 Pro valve the 69 pro valve and the 67-68 valve Some call them Pro. valves others metering. Most appear to use the 68 or 69 valve. I believe since my car was one of the first hundred made in CA. it had the 68 valve, then later was changed to the 69 valve. My car was someone's dragster for many years and thus many changes took place.  FYI Im 67 so I agree with you!
I blew up Johns pic and found the needed valve on line and ordered it complete with bracket and rubber boot. It will be here next week Ill replumb and report back. Tkx Jim

I have the factory distribution block and the new replacement is exactly the same. I have NO metering valve. There was one on the car originally and it was removed by someone who believed it improved that lock up problem as it was than worse then now. I now believe it was faulty and did not work correctly. I commented incorrectly when I called it the proportioning valve. I believe the metering valve is what I now need. If you agree what exactly can I order as all suppliers are calling that the proportioning valve?

I microed the rotors and they are exactly the same. I now believe it needs the 1969 disc brake proportioning valve as there is none on this system. I bought this car like this and did not change the set up. So I now believe this set needs that valve, don't you?

Today I installed the Calipers and bleed the system right side still locks up with easy braking? That means I have replaced everything the master cyl, the distribution block, the hoses. Ran new temporary front brake lines and the Right side still locks up. $300+ new parts and nothing made any difference. I am at a total loss. Any ideas?  Tkx Jim F

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
