Ray, The same thing happened to my 65 Belv. It sat for about 6 months. When I went to move it the brakes were tight. But I converted this car to power brakes. I forget what kit. It came with a couple different links to the pedal, and I believe also an adjustable rod. After I got it to move and let the pressure off at the M/C lines, it was better, but still hard pedal. I think in my case, I need to shorten the travel of the rod into the Booster. But at least it moves now and stops. Im gonna look into it more next week.... @halifaxhops
