Rear brakes will not return to normal position

first replace master cylinder the replace rear wheel brake cylinders.. Inspect front pads for non uniform wear, inspect front rotors replace if badly worn or scarred. You are dealing with 23-24 year old parts.

go to rear of car and wiggle, pull, push on the cables that go into the rear brakes. Sometimes this is all that needs to be done to release the brakes, then I suggest lubricate the brake cables, and/or inspect rear brakes. If this don't help, you could try to use some warm water and pour it over your brake drums, as snow and ice can freeze them up. Try a hairblower if its below freezing. If your brakes are not locked up, make sure your pedal return spring is working properly, sometimes its on the pedal, but most times its under car attached to the cables somewhere.

Removal
1.Remove rear wheel and tire assembly from vehicle.

2.Remove rear brake drums from hub and bearing assemblies after loosening the two brake drum screws.

3.Be sure that the parking brake pedal is in the release(most upward) position.

4.Completely loosen square nut of the rear parking brake cable. Then create slack in the rear parking brake cables.

5.Remove adjuster spring from adjust lever and brake shoe.

6.Remove adjust lever and turn the adjusting wheel of adjuster assembly to the direction of the arrow as shown.

7.Remove the strut spring and the lower retracting spring from the brake shoe.

8.Remove the upper return spring from the brake shoe.

9.Remove brake back plate hold down spring and pin from the leading brake shoe assembly.

10.Remove the leading brake shoe. Then remove the adjuster assembly, strut and anchor spring from the trailing brake shoe.

11.Remove the trailing brake shoe from the brake back plate after removing hold down spring and pin.

12.Remove the trailing brake shoe from the rear parking cable.

13.Remove parking pivot lever from the leading brake shoe.

Replacement
1.Lubricate the eight shoe contact areas on the back plate and anchor.

2.Install the trailing brake shoe to the rear parking cable.

3.Install trailing brake shoe on brake back plate and install the trailing brake shoe hold down spring and pin on the brake shoe.

4.Tighten the square nut of rear parking cable.

5.Install the anchor spring then install adjuster assembly, and strut.

6.Install leading brake shoe on brake back plate.

7.Install the brake shoe upper return spring, strut spring and the lower retracting spring to the brake shoe.

8.Properly rotate the adjusting wheel of adjuster assembly to the direction of the arrow in as shown.

9.Install the adjuster spring on the adjust lever and leading brake shoe assembly.

10.Install the leading brake shoe hold down spring and pin on the brake shoe.

11.Adjust brake shoes assemblies so as not to interfere with brake drum installation.

12.Install the rear brake drums on the hubs.

13.Check and adjust whether the pedal stroke in the specification.(Refer to section BR Gr./On-vehicle service/Pedal stroke of parking brake)

14.Install wheel and tire.

15.Push the parking brake pedal to the floor once and release pedal. This will automatically remove the slack from and correctly adjust the parking brake cables.

16.Test the vehiche on the road. The adjust will continue the brake adjustment during the road test of vehicle.

Inspection
1.Inspect the disassembled parts for wear, rust or damage.

2.Measure the thickness of brake shoe lining.
Standard : 0.17 in (4.5 mm)
Minimum : 0.04 in (1 mm)

3.If the shoe lining is less than minimum or shows signs of uneven wear, replace new one.

4.Measure the inside diameter of the brake drum.
Standard : 10 in (254 mm)
Maximum : 10.07 in (256 mm)

5.If the inside diameter of the brake drum is more than maximum or shows signs of uneven wear, replace new one.

6.Inspect the lining and drum for proper contact. If the contact condition is improper, repair it with a grinder or replace the brake shoe assembly.

Symptom: Brake Pedal Pulsates Change When: Braking Change Where: Passenger Compartment Change -->
Priority Action Part Type Cause 1 Inspect Brake Drum Specs Brake Drum Out of Adjustment, Out of Round, or Cracked. 2 Inspect Brake Drum Unevenly Worn or Out of Round Brake Drum(s). 3 Inspect Brake Rotor Incorrectly Machined Brake Rotor. 4 Inspect Wheel Bearing-Front Incorrectly Tightened or Installed Wheel Bearing. 5 Inspect Wheel Bearing-Rear Incorrectly Tightened or Installed Wheel Bearing. 6 Inspect Wheel Nut Loose, Worn, or Damaged Wheel Nut(s). 7 Inspect Rear Axle Bent Rear Axle.

The extra brake travel can be;
1. air still in the brake lines and need bleeding
2. if there are brake drums on the rear they may be out of adjustment
3. if there are warped brake disc or caliper problems that will add to the brake travel

After you remove the tire, the drim should slide off. If it doesn't then try using a rubber mallet and gently tap on the outside edge as you pull on it. Sometimes you also need to tap on the drum in the center part. I have sprayed penetrating lubes like WD-40 or PB Blaster into the seam at the center. You may also have to back off the parking brake cable or even use the adjuster to back off the shoes.

You will have to turn the drum,and adjust accordingly,adjust them little by little,until the drum drags on the brake shoes,adjust them until they drag,but you can still turn the drum by hand,you might want to remove the drum first,just to make sure the brake shoes are not too worn,and need replacing.If this was a t all helpful,please rate,thank you.

start by bleeding the brakes, readjust the rear, make sure the calipers are sliding free, a bad wheel bearing can also cause a problem

i think your aware of how to change the brakes if im right and your problem is the rusted drum doesnt want to come off the only way to get the old drum off is to remove adjuster plug from behind drum dustshield and adjust the shoes so that there not even close to the braking area of the drum then try and wiggle the drum off of the assembly if it is not coming off then you need to use the old nylon hammer on the drum and i mean you must hit the drum from side to side trying by hand to wiggle the drum off its a tight fit and you need to strike the drum on the face not on the fins not wanting to damage with persistance and care and patience you will eventually be able to remove the drum to service brakes take care and good luck with it
