Hi Scotty. I replaced caliper because of overheating. New caliper got stuck even more. After I replaced hose. No change after that. After I started to think about master cylinder. But caliper wont go back so I wondering if it cant be master cylinder. Because if master would be bad it would be possible to push back caliper or? I have to open bleeder to push caliper back. I drive two weeks on handbrake now :D.

master is bad or rubber line that feeds the calliper is clogged up inside and won't release

Thank You. Rubber line is called brake hose in England :). I try change that master but it its 15% of value of car. I like old cars too...
