on the rear end behind the rotors, theres, i guess you can say a plate like thing, or a disk like thing. what is that called?

I assume you're referring to the backing plate, upper right of the pic.

yes! thats exactly it! thanks i plan on replacing at least one bc it had rust holes in it. do they sell those or am i gonna have to go junk yard hunting?

EDIT: i looked around and found this http://www.gmclassicparts.com/BRAKE-...-_p_22759.html did they change how they look bc it doesnt look like the one in your picture.


and another but dumb question, but how exactly do i take off the calipers?

Looks to be a drum backing plate. I searched for a part number for the disc version but came up empty. The bone yards are full of these parts--and I'm sure many TGO members who've converted to larger discs would be able to help you out, so you might consider the classifieds (I threw mine away or they'd be yours for shipping).

The following from Chilton's (diagrams and blow-ups would make the info a bit easier to understand, though it's not rocket science. BTW, one of the first purchases a car guy should make is a shop manual, indispensable). I haven't messed with the old-style calipers in a long time, so there are no doubt shortcuts. Perhaps a search would be in order:

Brake Caliper: Removal and Installation

1982-88

1. Remove 2/3 of the brake fluid from the master. Raise the car. Remove the wheel. Reinstall a wheel nut, with the flat side toward the rotor, to hold the rotor in place.
2. Loosen the parking brake cable at the equalizer. At the caliper, remove the parking brake cable, damper and spring from the lever.
3. Hold the parking brake lever and remove the lock nut. Remove the ever seal and anti-friction washer.
4. Position a C-clamp over the caliper and force the piston into its bore. Remove the C-clamp. Reinstall the lever, seal, and nut to the caliper.
5. Loosen the brake tube nut and disconnect the brake tube from the caliper. Plug the tube to prevent the loss of brake fluid.

At the right rear wheel, it may be necessary to remove the rear bolt from the lower control arm to allow the lower caliper mounting bolt to be removed.

6. Remove the mounting bolts using a 3/8" allen head socket. Remove the caliper and inspect the mounting bolts for corrosion. If necessary, replace the mounting bolts.
7. To install, place the caliper onto the rotor and install the mounting bolts. Torque the mounting bolt to 30-45 ft. lbs.
8. Install a new anti-friction washer and lubricate the lever with silicone brake lube. Install the lever on the actuator with the lever pointing down. Rotate the lever toward the front of the car and hold while installing the nut. Torque the nut to 30-40 ft. lbs., then rotate the lever back against the stop on the caliper.
9. Install damper and spring. Connect the parking brake cable. Tighten the cable at the equalizer until the lever stars to move off the stop on the caliper, then loosen the adjustment until the lever moves back against the stop.
10. Remove the nut holding the rotor in place and install the wheel. Lower the car and fill the master with brake fluid.
