Thanks folks. I'm fairly certain it isn't cable tension, both front and back have similar tension - front brakes ok, rear doesn't.
Still feels as though there's some containment in there. Can hold the brake on full and still spin the rear wheel with my hand.
Pads are generic branded Giant ones, will try something better. Also tempted to buy a new rotor just to rule that out as well
