I’d be very surprised if it were the master cylinder causing this problem, it sound more like calliper problem as you mentioned that it was very difficult to push the piston back in, the master cylinder dose not pull the piston back into the calliper. Have you checked the pistons themselves? Is there any sign of rust around them as this could prevent them from returning into the calliper, the pads should run with very little gap between then and the disk. I would suggest that the rear calliper is striped, cleaned and checked for free movement.
Hope this helps.
