An 85 should have the 2 piston calipers. No guide pins or floating
assemblies. Rebuilt calipers are probably available through a local flaps
and can probably get hem for under $100.

Cleaning may work. I'll bring some calipers just in case. I'm hoping to
drive it back without any towing, but AAA+ if it's needed.

general comments. There are two main spots where corrosion can cause a
caliper to seize up; the piston itself and the caliper bolts or pins that it
slides on. If the pins are sticking, but can be forcibly pulled out, the
rust can be scraped and sanded away and the holles cleaned out. A round
file may be helpful here. Relube with caliper grease.

With the caliper removed from the disk, you can extend the piston by
pressing hard on the brake pedal. You must prevent the piston from blowing
out completely by placing pieces of wood of the proper thicknes where the
disk would be.

special tool baorrowed from your FLAPS. Repeat this process as many times
as you have patience for. Keep an eye on the fluid level in the resevoir
at the master cylinder, especially when pushing the pistion in.
