I have a 1969 Camaro that I installed rear disc bakes from a 1979 Trans Am on. I installed them based upon an article I read from a September 1981 Hot Rod magazine. I had read the article and happened upon a rear end from a 79 TA in my local junk yard shortly after that. My problem is that I can't seem to get all of the leaks in the rear brakes stopped. I've got an adjustable proportioning valve and am using a new brake booster and master cylinder for a 79 TA. All of my rear lines from the proportioning valve back are new stainless steel from Ricks First Generation and Classic Industries. The front rear line is for a 1969 Camaro and the axle lines are for the TA. All of the leaks are at the calipers. They appear to be from where the adapter for the brake lines hook up. I've tried different rebuilt calipers from my local auto parts stores, new copper gaskets, and bleeder screws and met with some success but still have not been able to get rid of all of the leaks. Any words of wisdom form anyone who has had to deal with the rear disc brakes on a 1979 TA? I've got a lot of cash and time tied up in these brakes and would like to get them to not leak. I started this in 1981 long before conversion kits were readlily available. Life got in the way and I would hate to have to flush all my investment and get something from Stainless Steel Brakes or someone like that. Thanks for any help anyone can be.
