So my calipers on my 82 320 were not releasing. Took them apart, cleaned them up, reassembled, bleed them. Frozen again. So I figured as long as I needed new calipers might as well upgrade to the volvo brakes I read about on this forum. Got them installed, bleed. Not releasing. Probably not frozen in the 1st place.
Any idea if the proportioning valve can cause this or master cylinder or rubber lines?
A master cylinder can cause it if it is adjusted incorrectly to where the piston does not come fully back to its stop after you hit the breaks, as in if the rod adjusted too tightly against the brake pedal, you have to leave it some slack to fully come back like you would a motorcycle clutch..
What Volvo calipers are they exactly? Are they by chance the early 90's 240 4pot calipers with the single brake line?

I'll check that out. Thanks. the Volvo brakes have to lines so I had to make a T fitting.
Right, those are the earlier non-abs cars with 2 lines.. I think their are also narrow disk and wide vented disk versions of the Volvo 4pot calipers but they all mount the same..
I'm just interested because I have Volvo calipers on my 931 and if they fit the e21 too then I guess that means that all the early 944 caliper options work on the e21, and vice versa, which is interesting..

Not it. I adjusted it all the way out and the brakes are still not releasing.
Yes the rubber hoses COULD cause that, if they are very old. Hopefully you've replaced them?.. or rubber lines?
