Handbrake adjustment

I've got new rear calipers and new handbrake cables. When adjusting the handbrake I've noticed one side doesn't quite spin freely when the handbrake is released no matter how much I adjust it. Any ideas why this could be happening?
 
did you check the handbrake cable length you might have been given the wrong one, the handbrake cables attach to a bar pulled buy one cable which helps balance the lengths if its all one way towards the tight wheel most likely the cable is too short.

Yeah the handbrake cables are both the same length and they both move the same when the handbrake is pulled
