Help: Sticky parking e-brake cable

[bman]

I noticed that the rears were sqeeking while in reverse so I took off the tires and I noticed that the driver's side parking brake / e-brake wasn't releasing. Even after pulling on it with a pair of pliers it took a hard yank to get the cable to let go. This is down by the wheel. I couldn't find anything that the cable was hung up on. Do I need to replace the cable? Is it something that I should try in my driveway? The passenger side works fine.

Thanks,
Brian
