Re: where doe's that spring go on rear brake drums 1996...
There should be several springs. first there are (2) real short springs that hold the shoes to the dust cover/back plate. they go in the center of each shoe. then there is a short spring that goes at the bottom where the adjuster is located. there should be a hole in each shoe. finally there is a long spring that goes at the top where your brake cylinder is and this is what gets attched last after your emergancy brake levers are placed between the shoes .

if you have rear drum brakes a return spring that pulls the brake shoes back to the unapplied position or a hold down spring may have broken which is now causing the brake shoes on that wheel to be applied causing the drag not all people bought there cars and trucks with 4 wheel disc brakes it was cheaper and didn't matter to them they just wanted lower $$$ check it out if this is the case you'll have to turn the adjuster star wheel inside the drum all the way in to get the drum off because the brake is applied it will be a pain but you'll get it you must use a brake spoon or a flat blade screw driver and a smaller one to lift up the return spring arm from the star wheel if this one is broken you will have to try to pry the drum off then buy a spring kit from auto parts and some brake tools if you don't have them already and change all the springs one by one so you don't get confused but also try to get a rear brake shoe diagram in case everything has fallen apart inside and you remove the drum and find a whole bunch of parts on the floor in front of you the diagram will give you the aid that you'll need if you have never done this before most of all inspect that wheel cylinder for leaking fluid if this is so replace it now good luck LATER MAN!

Apply a light coating of caliper slide grease to the backing plate brake shoe contact areas.
Apply a light coat of lubricant to the threaded areas of the adjuster screw and socket. Assemble the brake adjuster with the stainless steel washer. Turn the socket all the way down on the screw, then back off 1?2 turn.
Install the parking brake lever to the trailing shoe with the spring washer and a new retaining clip. Crimp the clip to securely retain the lever.
Position the trailing shoe on the backing plate and attach the parking brake cable. Position the leading shoe on the backing plate and attach the lower retracting spring to the brake shoes.
Install the adjuster assembly to the slots in the brake shoes. The socket end must fit into the wider slot in the leading shoe. The slot in the adjuster nut must fit into the slots in the trailing shoe and parking brake lever.
Fig. 10: Install the adjuster assembly in the slots in the brake shoes
Install the adjuster lever on the pin on the leading shoe and to the slot in the adjuster socket.
Install the upper retracting spring in the slot on the trailing shoe and the slot in the adjuster lever. The adjuster lever should contact the star and adjuster assembly.
Install the brake shoe anchor pins, springs and retainers. Remove the brake cylinder clamp tool
Install the brake drum, wheel and tire assemblies and lower the vehicle.
Apply the brakes several times while backing up the vehicle. After each stop, the vehicle must be moved forward.
Try these: 1. Most of the current shoe/drum systems on the rears have self-adjusters that are designed to advance the adjuster wheel when you back up briskly and slam on the brakes. You may need to push the flat metal self-adjuster tab out of the way of the starred adjust wheel. If you don't you can be only pushing on it so far and then it's just going to spring back. Take a flashlight and look closely in the adjuster hole, see if you can find the metal tab. It will be on the far side away from the adjuster hole. Push the tab farther away from the star wheel and then stick the adjuster tool in on the star wheel and give it another try.
2.You may be tightening the shoes into the drum instead of loosening them. Try turning the adjuster in the other direction.
3. Get some spray lube/ with a small tube to attach to the spray head. Stick the spray tube in the adjuster hole and spray as much as you can of the adjuster.
Hope this gets the drums off for you...please let me know how it goes.
You can adjust the shoes outward on the rear by removing the wheels and drums, then above the axle but below the wheel cylinder you will see an arm that is horizontal, pushing both of the shoes outwards. There should be an adjustment nut that you can turn to extend the arm to push the shoes out.
REMOVAL & INSTALLATION If
you are not thoroughly familiar with the procedures involved in brake
replacement, only disassemble and assemble one side at a time, leaving
the other wheel intact as a reference. 1983-88 Vehicles See Figures 1, 2 and 3
Raise and safely support the rear of the vehicle with jackstands.
Remove the tire and wheel assembly.
Remove the brake drum, as outlined earlier in this section.
Place Brake Cylinder Clamp D81L-1103-B or equivalent, over the ends of the brake cylinder.
CAUTIONBe careful that the springs do not slip off the tool during removal, as they could cause personal injury.
the shoe-to-anchor springs, using Brake Shoe R and R Spring BT-11, or
equivalent, then unhook the cable eye from the anchor pin.
1: Place the brake clamp tool over the ends of the wheel cylinder, then
remove the shoe-to-anchor springs using the correct tool
Remove the shoe guide (anchor pin) plate.
Remove the shoe hold-down springs, shoes, adjusting screws, pivot nut, socket and automatic adjustment parts.
Remove the parking brake link, spring and retainer. Disconnect the parking brake cable from the parking brake lever.
removing the secondary brake shoe, disassembly the parking brake lever
from the shoe by removing the retaining clip and spring washer.

brake cable must be connected to the secondary brake shoe before the
shoe is installed on the backing plate. To do this, first transfer the
parking brake lever from the old secondary shoe to the new one. This is
accomplished by spreading the bottom of the horseshoe clip and
disengaging the lever. Position the lever on the new secondary shoe and
install the spring washer and the horseshoe clip. Close the bottom of
the clip after installing it. Grasp the metal tip of the parking brake
cable with a pair of pliers. Position a pair of side cutter pliers on
the end of the cable coil spring, and using the plier as a fulcrum,
pull the coil spring back with the side cutters. Position the cable in
the parking brake lever.
Apply a light coating of high
temperature grease to the brake shoe contact points on the backing
plate. Position the primary brake shoe on the front of the backing
plate and install the hold-down spring and washer over the mounting
pin. Install the secondary shoe on the rear of the backing plate.
Install the parking brake link between the notch in the primary brake shoe and the notch in the parking brake lever.
Install the automatic adjuster cable loop end on the anchor pin. Make sure the crimped side of the loop faces the backing plate.

sure the flared hole in the cable guide is inside the hole in the brake
shoe. Fit the cable into the groove in the top of the cable guide.
the secondary shoe return spring through the hole in the cable guide
and the brake shoe. Using the brake spring tool, slide the top of the
spring onto the anchor pin.
Clean the threads on the adjusting
screw and apply a light coating of high temperature grease to the
threads. Screw the adjuster closed, then open it 1/2 turn.
the adjusting screw between the brake shoes with the star wheel nearest
to the secondary shoe. Make sure the star wheel is in a position that
is accessible from the adjusting slot in the backing plate.
Install the short hooked end of the automatic adjuster spring in the proper hole in the primary brake shoe.

will pull the cable and spring with it) downward and to the left and
engage the pivot hook of the lever in the hole in the secondary brake
Check the entire brake assembly to make sure that
everything is installed properly. Make sure that the shoes engage the
wheel cylinder properly and are flush on the anchor pin. Make sure that
the automatic adjuster cable is flush on the anchor pin and in the slot
on the back of the cable guide. Make sure that the adjusting lever
rests on the adjusting screw star wheel. Pull upward on the adjusting
cable until the adjusting lever is free of the star wheel, then release
the cable. The adjusting lever should snap back into place on the
adjusting screw star wheel and turn the wheel one tooth.
Expand the brake adjusting screw until the brake drum will just fit over the brake shoes.
Install the brake drum and wheel and tire assembly, then adjust the brakes.
