The feel and sound of the pull of the e-brake lever has suddenly changed on my car. It used to engage and click nice and bright, now the pull is definitely harder and I was hearing a few pops coming from the rear end. The brake does engage. When I look at the rear end, the cabling assembly for the e-brake seems to have slack to it. I don't remember if that slack was already existing or not. Does this sound like and issue with the lever or the shoes/springs?
