The parking brake on the AAM 11.5 axle is a miniature old fashioned drum brake setup inside the rotor hat. The caliper is a good old fashioned disc brake caliper. Crack the bleeder and push the piston back then gravity bleed it while keeping the master full of fresh fluid to clear the 20 year old brake fluid out.

Rotors should be right around $50-$70 each.
Quality pads are about $40-$50.

The parking brake is about $30 in parts, shoes and spring kit, if the backer plate and cables are serviceable.

So $220 in parts if you use the high numbers. That's about $140 in labor. Depends on how cash strapped you are whether it's worth the couple hours of your time kneeling in the gravel in the cold to do the brakes yourself.

I would replace the rotors and parking brake shoes in any locality that you drive in the snow because they tend to get pretty rough. You can do a pad slap and ignore the parking brakes for about $50.
