Parking brake cable stuck partially-applied. Restricted rubber flex hose. Brake fluid contaminated with a petroleum product.
Park on a slight incline, shift to neutral, and verify the vehicle won't creep downhill on its own. Crack open the steel lines at the master cylinder. If the brake releases, suspect contaminated fluid. If it doesn't release, open the bleeder screw on the caliper. If it still doesn't release, suspect the parking brake cable.
