The front parking brake cable is usually rusted. Functional, but a PITA to release.

On the caliper there is a lever like arm which has a spring that basically releases the caliper parking break. This lever/arm tends to rust and then doesn't rebound properly. It could also possible be your calipers. A lot of people have these problems with the 88 and 87 style caliper parking brakes. Have fun.
