Thank you for the reply. Yes, the car has drum brakes on the rear and there are no proportioning valves. The master cylinder has 4 brake lines the bottom two ports on the master (closest to the push rod when mounted) go to the rear brakes, the top two to the front brakes each brake having a separate line. To adjust the rear brakes, I usually jack the back up, release the hand brake, and adjust so I get a little bit of drag when rotating each drum by hand, I then apply the hand brake a click and if I can't turn the hub by hand I know it is about on and it passed the hand brake test anyway.
Now if I were to loosen off the right rear brake (the one with more force when applying the foot brake) my worry is it might not pass the hand brake test, because I would have deliberately made my own imbalance and not actually resolved the problem.
