Rusty and dirty calibers, rusty mounting points, rusty caliber slide pins, or contaminated brake fluid. Brake fluid absorbs moisture and I would bet yours is severely contaminated. Completely flush your entire brake system and replace with the proper fluid from and unopened can. Bleed the brake system and see what you have at that time. Replace the guide pins if they are rusty or pitted. Lubricate them with silicone brake lube. Clean off all mounting points with a wire brush, do not use a grinder. You may need to replace the calibers to completely solve the problem. Brake fluid should be changed every 36,000 miles at a minimum.
Contaminated fluid? Frozen calipers?
Yes. If your question is regarding the operation of the calipers. They do operate in the same manner as the front calipers.
NO. The size of the tires and wheels have NOTHING to do with the brakes.
first remove the calipers from the carrier then remove pads then calipers can not be pressed in you must use a tool to turn them in, then reinstall in reverse order
no
Warped brake rotor(s). Brake pads and calipers should also be inspected.

how do you adjust rear brakes on a 1986 chevy silverado?
First id have to get my back brakes on your Chevy 2500 silverado.
No.
The calipers or wheel cylinders are bad.
The 1997 Chevrolet Silverado rear brakes should automatically adjust themselves. Every time you back the vehicle up and hit the brakes the brakes adjust.
