I've been noticing as of late that, occasionally, my parking brake won't disengage all the way. The brake itself doesn't stick (the car isn't sluggish or smelling funny), but it'* engaged just enough to keep the brake light on and dinging at me. Once I kick it up, it'* back to normal. Here'* a video.

Thoughts? I'm guessing a nut is loose.

Hahahaha Might be the return spring.

If it helps you diagnose, this happens more often when I keep my foot on the (regular) brake while disengaging the parking brake.

Any tests I can do to better troubleshoot?

Check the return spring and the fluid level in the master cylinder.

The master cylinder was missing about half a bottle'* worth of brake fluid. Didn't seem to make any difference, though. I'll see if I can get a good look at the spring tomorrow morning.
