CAUTION Older brake pads or shoes may contain asbestos, which has been determined to be cancer causing agent. Never clean the brake surfaces with compressed air! Avoid inhaling any dust from any brake surface! When cleaning brake surfaces, use a commercially available brake cleaning fluid.

1. Remove 1 / 2 of the brake fluid from the master cylinder reservoir.
   
2. Raise and safely support the vehicle.
   
3. Remove the wheels.
   
4. Remove the cotter pin and guide pin.
   

Fig. 1: Rear disc brake components

1. Remove the caliper locating pin cover and remove the locating pin.
   
2. Swing the rear disc brake caliper away from the brake rotor and anchor plate. There is no need to remove the parking brake cable or brake hose.
   
3. Remove the inner and outer disc brake pads.

To install:

1. If installing new disc brake pads, use rear caliper piston adjuster T87P-2588-A or similar tool, to rotate the rear disc brake piston clockwise, retracting the caliper piston. This will allow room for the new brake pads.

13. Road test the vehicle and check for proper brake system operation.

Hope this helps (remember to rate and comment this answer).

Rear disc brake pads offer better performance and are not as affected by moisture like conventional brake shoe style brakes are. Rear disc brakes are similar to front disc brakes. The main difference is that rear disc brake systems must incorporate the emergency brake system. There are two methods widely used for the emergency brake with rear disc systems. The first system is a brake shoe inside the brake disc that is actuated by the emergency brake lever. The second is a screw style actuator inside the brake caliper. When activated the brake pads are forced into the brake disc and held tightly by the emergency brake lever.
READ COMPLETELY BEFORE STARTING
Step 1 - Identify Rear Disc Brake Components
Rear disc brake assembly includes; rear brake disc, rear brake pads, brake caliper mount and a caliper mounting screw. (Note: Some vehicles do not have the rotor mounting screw.)
Step 2 - Removing the Rear Brake Caliper Mount Bolts
To replace rear brake pads and rotors the rear brake caliper needs to be removed. First loosen the rear brake caliper mount bolts and remove them. Turn counter clockwise.
Step 3 - Lift Rear Brake Caliper from The Caliper Mount
After the caliper mount bolts have been removed, gently lift the brake caliper from the caliper mount. Inspect the caliper slides; they should move freely in the caliper mount. Remove rear brake pads and hardware.

Step 4 - Removing Caliper Mount Bolts
With a socket wrench or other appropriate removal tool, loosen the rear brake caliper mounting bolts. Remove bolts and lift the caliper mount and remove it from the vehicle. Remove the retaining screw from the disc mounting hole. Tap the rotor gently to release any rust that has accumulated between the rotor and bearing hub. Lift brake rotor from wheel hub holding on tightly, using both hands. You do not want to drop the rotor.

Step 5 - Removing Rear Brake Rotor
Remove the retaining screw from the disc mounting hole, tap the rotor gently to release any rust that has accumulated between the rotor and bearing hub. Lift brake rotor from wheel hub, hold on using both hands and do not drop.

Step 6 - Install New Brake Rotor
Check the new rotor against the old brake rotor to make sure they are the same size. Clean the mating surface on the wheel hub before the new brake rotor is installed. Reinstall rotor retainer screw.
Step 7 - Reset Rear Brake Caliper
Before new brake pads can be installed, the rear brake caliper must be reset. The reset tool winds the piston back into position so the new brake pads will fit. This style of brake caliper will not compress with a clamp tool; it can only be reset with the proper reset tool.
Step 8 - Reinstall Rear Caliper Mount and Install New Rear Brake Pads
After the caliper has been reset, reinstall caliper mounting bolts and make sure the bolts are tight. Then match up the old brake pads to the new brake pads. They should be exactly the same except, of course; the old ones will be worn out. Check the new brake pads for proper fit and install any brake hardware that is required.
Step 9 - Remount Rear Brake Caliper
Reinstall the brake caliper, align brake pad hardware and reinstall caliper mounting bolts. (Note: align the rear peg of the brake pad to the groove in the caliper piston.) Recheck and retighten all caliper and caliper mount bolts. Bleed brake system to relieve any air in the system. Before driving the vehicle, push the brake pedal down and let it up slowly. This operation forces the brake pads to travel to the brake rotors. DO NOT DRIVE VEHICLE until proper brake pedal operation resumes. When test driving vehicle listen for any unusual noises during the operation of the brakes.
WARNING! Always have the vehicle under inspection on level ground, in park with the emergency brake on. Always wear protective eyewear, gloves and necessary clothing before inspection or work begins. Never crank an engine over when anyone is near the battery or engine. Always have an operational fire extinguisher close by, obey all first aid instructions in the event of an injury. Never stand in front or behind a vehicle when cranked over or running. When engine is cranked over keep hands and clothing away from rotating components. Never move a car without proper brake pedal operation.

The Condision you Describe I Believe to be On the HYDROLIC SIDE of the System And Normaly Requires Replacement of Wheel Cylinder,Brake Caliper,, or Possible HOSE or LINE Also With it Wearing Brakes out THAT FAST It Will REQUIRE Drum or Disc Replacement of THAT Drum/Disc Due to EXTREME HEAT Conditions. I Recommend Replacing in PAIRS for Better & More ACURATE THICKNESS in FRICTION AREA

This Model Is Built with DRUM & DISC Brake SYSTEMS so More than A Few Causes Will Apply Here.
IF it is A DISC System Then A FROZEN or STICKINN PISTON in the CALIPER Would Cause this, ALSO a PERFECTLY GOOD LOOKING BRAKE HOSE (Rubber) At Said Wheel Can Be BLOCKED INSIDE and in BOTH Systems A SMASHED Brake line (Steal) will Cause this.
The PARK BRAKE Cable on that side ALSO will cause this.

LAST I Believe is A STICKY or LEAKY WHEEL CYLINDER Will DO It

IN ALL CASES REPLACEMENT OF PARTS SHOULD BE IN PAIRS AS BRAKE SYSTEM IS CREUCIAL I Hope this is of Some Help to You. Feel Free to Email ma at rejakwilson @ aol.com
