Front calipers not releasing

The line above the brake switch in the second photo looks pinched.

IMHO I would bite the bullet and buy new OEM reproduction lines and the year correct distribution block and proportioning valve.

There could still be a lot of trapped air in the lines.even if fluid flows out clear. Think aeration.

Do you know for sure the combo block and proportioning valve is functional?

Been a while figured I'd give an update for all that helped and quoted you because... I took your advice and I got new brake lines and my brakes work amazing now! Was able to lock up the wheels for the first time ever. My pedal is a nice firm hard pedal.

I actually made the new brake lines myself and did this because even though my brakes have worked since this thread I was never happy with the pedal feel of them. First push was always a little soft but no matter how many times I bled them I couldn't get the problem corrected.

New lines and fittings, no leaks and amazing brakes. Life is good!
