[Healeys] BJ8 Rear Brake

NeilMaybe its not the cylinder retracting in the bore. Does the cylinder body slide easily in the backing plate? P

 I had to replace a leaking, original wheel cylinder (drivers side) earlier. Everything went fine with the install & adjustment, except that on its inaugural run, it became quickly apparent that things were not right.  Took the drum back off again, only to find that the cylinder was not retracting properly.   Group wisdom from the internet says you need to replace the rubber pipe.No problem - except there is only 1 of these rubber brake pipes that goes into a T to feed both rear brakes - and the problem is ONLY with the driver's brake - the passenger side rear wheel cylinder retracts like a champ. Driver's side spring is ok btw. So what I don't understand is - if the inside of the rubber pipe was swollen, not letting fluid back through, wouldn't this affect both rear brakes, not just one of them?
  Should I replace this one hose, or did I get a "bad" wheel cylinder from Moss? (yes, I ordered the cheaper aftermarket cylinder @ $14 as opposed to the TRW brand cylinder @ $70), or do I replace both? or?
  Lastly, what is the min thickness of the rear shoes? Both are evenly worn & about the same thickness as the metal mounting plate underneath.
  Thanks in advance,
Neil _______________________________________________
