Brakes on my 82 brat are not releasing pressure after breaking. Calipers will release when I turn the bleeder screw and about a tablespoon of fluid spits out under pressure. Rubber hoses have been replaced and the caliper and piston inspected and cleaned. I'm starting to think it might be something in the hilholder/fluid diverted mechanism? The cable on the hilholder was removed long ago and adjusting by hand the hilholder lever under the master cylinder doesn't seem to do anything to help. Anyone else ever had this problem or have a suggestion? Thanks

You can replace the hill holder with a simple splitter like the one next to it, that will eliminate any problems from the hill holder.
