Maintenance / Re: 69 RF brake lock up?

A final follow up on my continuing right front brake problem. If you read back you will see I replaced every brake component that was new when I bought the car 5 years ago. I have learned much that all said in the end I bought a USA made Pressure control valve and inserted between the MC and the RF brake and set at almost zero it solved the problem of the RF brake always locking up and to recap. Not only did I change every component I swapped the left to right and back again. I also swapped right to left line and back again. I ran new temporary lines and absolutely nothing make a any difference.
After finally finding someone who understood why its happening but not how to instantly repair it. Its due to quality control of imported parts. Lines, calipers, rotors etc are not all machined in matching sets or to a high standard and there lies the problem. Tkx for all your suggestions over the years!

Sorry I have not been on all summer. I was completing my 70 Chevelle full restoration, also did a 71 Rolls coupe and just now finished a 89 Jeep YJ. I drove the Camaro approx. 1000 mi this summer with the brake problem. I have replaced and tested every brake component and in the end nothing helped! RF still locks up under light pressure. I even gave the car to another 40 yr experienced mechanic who swapped and tested everything and accomplished nothing. Spoke to several experienced muscle car specialist around the US and to date its still exactly the same. So for now It will stay like it is as I can drive around it and have for 4 years now. Over the winter I may go it once again. Tkx Jim F

I saw this today. It appears correct but will take much to take it back to original. Otherwise nice project car.

69z27, I did have a rear leak in new cylinders and changed that one re adjusted both right front still locks up. I sort of gave up as I changed everything and it made no difference.  I have been driving it that way now for close to 5k mi. I know how to stop without locking by just slowing down gently.

How far down does the switch go now? Mone only goes half way. I may have same symptoms. DI'd you change the cables at the heater side only?

Dave I didn't actually measure the front but I have set up on a 4 wheel alignment machine. It was a dag car years ago but I figured the 4 wheel adj would catch that? 
After I wrote that paragraph I took the old girl out for a drive and after my last plumbing which was to put the left wheel into the larger hole of the distribution block on fender side and the RF to the engine side and smaller hole and the MC to the front center hole the car was much better. I drove on back roads and braked a lot and as long as I didn't HIT the brakes but only pushed on them the car was fine. Though even at slow speeds, like approaching a light if I pushed a bit harder it would lock up and release. The way it is now seems to work better then it ever did though not perfect. Since it is a 4 speed with huge torque and compression the car always slowed easily. I can def live with it like this or until I find the answer. Tkx Guys! Jim

I bought it from Groundup 396. I checked both the old original and new replacement and both are cast and the only differences I can see are all 3 front end holes are all 1 drill size larger then the original . That also is 1 large and 2 small holes. The one to the left of the brake switch is the larger in both cases and the front center and engine side are both small. I have plumbed both all 3 possible ways and made no difference.

Dave I spun the wheels on my lift and rf still locks up. Thus a.m I re plumbed yet again and ran the left front to the largest hole and rf to the smallest hole in the distb.block and it rf still locks up. FYI my garage is 100 ft long. I back off the lift to the door drive aprox. 59 ft and just push on the brakes to stop as normal rf always locks up and releases once foot is lifted a bit. I have now plumbed to every combination,  replaced everything except booster and hard lines to wheels. Nothing helps. I may need to order a complete booster mc kit and start over. I also may try an line reducer valve.

Dave in earlier post I explained every detail with current pic and factory pics I have replaced everything except the booster and the 2 main twisted supply lines. I blew those out I even ran temporary line to both to test. I explained in the previous post those reducers were temporary just to test. I changed the plumbing 3 times I did use factory specs I rebuilt the rears too because 1 leaked. The car always stops and the RF always locks up 1st and then releases. Nothing has changed in 3 years and 6k mi and this is the 2nd time Im doing everything. I have had several 40yr experience mechanics stop at my shop and advice from many on line and nothing works. I try something new every few days I even tried a different distb. block with larger holes to the RF. Im at a total loss.

I'll elaborate,  the block has 3 holes which I large 2 smaller It came to me with one small to one side  one small to supply one large to rightwheel, though I didn't know that until today.  I re plumbed it one large to supply 2 small hole each to one wheel. Still locked up rf wheel.
I'm looking into an in line reducing type valve.
