What is the proper adjustment/
Head light adjusters are part of the head light assembly and yes high and low beam are adjusted as one unit normally. Proper adjustment is done on a machine, at an equipped facility.
REMOVAL & INSTALLATION It is a good idea to only disassemble and assemble one side at a time, leaving the other side intact as a reference.
Raise and support the vehicle safely.
Remove the brake drum.
Disconnect the parking brake rear cable and conduit.
Remove the brake shoe hold-down springs and brake shoe hold-down pins.
Remove the brake shoe adjusting screw spring.
Remove the brake shoe adjusting lever and adjuster screw.
Remove the brake shoe retracting spring.
Remove the brake shoes from the backing plate.
Remove and discard the parking brake lever clip. Remove the washer.
Remove the parking brake lever from the rear brake shoe.
Thoroughly clean the backing plate with brake cleaning solvent and dry completely.
Use silicone grease to lubricate the brake backing plate-to-brake shoe contact areas.
Apply a light coating of premium grease to the threaded areas of the adjuster. Turn the adjuster in and out to spread the lubricant. Turn the adjuster all the way down on the screw and loosen one-half turn.
Install the parking brake lever to the rear (secondary) brake shoe with a new clip.
Position the brake shoes on the backing plate and install the brake shoe hold-down springs.
Attach the parking brake rear cable and conduit to the parking brake lever.
Attach the brake shoe retracting spring.
The socket end of the brake adjuster screw is stamped with "R" or "L" to indicate that it is to be installed either on the right (passenger's side) or left (driver's side) of the vehicle. The adjuster nuts can be distinguished by the number of grooves machined around the body of the nut. Two grooves indicate a right-hand adjuster nut and one groove indicates a left-hand adjuster nut. Another way to identify brake adjuster assemblies is to check thread pitch. The right side adjuster assembly has right-hand threads and the left side has left-hand threads. If installed correctly, the brake adjuster assembly will increase in length when the brake shoe adjusting lever is operated.
Install brake adjuster screw in the slots on the brake shoes. The wider slot on the socket end must fit in the slot on the front (primary) brake shoe.
Install the brake shoe adjusting lever on the lever pin.
Install the brake adjusting screw in the slot on the secondary brake shoe and in the slot on the brake shoe lever. The brake shoe adjusting lever should contact the brake adjuster screw.
Adjust the brake shoes.
Install the drums.
The drum brakes are self-adjusting and require a manual adjustment only after the brake shoes have been replaced, or when the length of the adjusting screw has been changed while performing some other service operation. Drum Installed
Raise and support the vehicle safely.
Remove the rubber plug from the adjusting slot on the backing plate.
Insert a Brake Adjustment Tool (D81L-1103-C) or equivalent into the slot and engage the lowest possible tooth on the starwheel. Move the end of the brake spoon downward to move the starwheel upward and expand the adjusting screw. Repeat this operation until the brakes lock the wheels.
Insert a small screwdriver or piece of firm wire (coat hanger wire) into the adjusting slot and push the automatic adjusting lever out and free of the starwheel on the adjusting screw and hold it there.
Engage the topmost tooth possible on the starwheel with the brake adjusting spoon. Move the end of the adjusting spoon upward to move the adjusting screw starwheel downward and contract the adjusting screw. Back off the adjusting screw starwheel until the wheel spins freely with a minimum of drag. Keep track of the number of turns that the starwheel is backed off, or the number of strokes taken with the brake adjusting spoon.
Repeat this operation for the other side. When backing off the brakes on the other side, the starwheel adjuster must be backed off the same number of turns to prevent side-to-side brake pull.
When the brakes are adjusted, make several stops while backing the vehicle to equalize the brakes on both of the wheels.
Lower the vehicle.
See Figure 2
Fig. Fig. 2: When using a brake adjustment gauge, first measure the inside diameter of the drum (top) and then adjust the brakes shoes to the proper outside diameter (bottom)
Remove the brake drum.
Make sure that the shoe-to-contact pad areas are clean and properly lubricated.
Using a Brake Adjustment Gauge (D81L-1103-A) or equivalent, check the inside diameter of the drum.
Measure across the diameter of the assembled brake shoes, at their widest point.
Turn the adjusting screw so that the diameter of the shoes is 0.030 in. (0.76mm) less than the brake drum inner diameter.
Install the drum.
See Figure 3
Fig. Fig. 3: Measure brake shoe thickness in several places around the shoe
Inspect the brake shoes for wear using a ruler or Vernier caliper. Compare measurements to the brake specifications chart. If the lining is thinner than specification or there is evidence of the lining being contaminated by brake fluid or oil, replace all brake pad assemblies (a complete axle set).
First you have to compress the parking brake cable spring and attach the parking brake lever.
Clean and lubricate the brake backing plate.
Use silicon Brake Caliper Grease and Dielectric Compound.

2. Release the brake shoe adjusting lever cable and check that the brake shoe adjusting lever advances to the next notch on the brake shoe adjusting screw nut.
You cannot adjust the cables on a minivan manually. the tension is
automaitcally adjusted by the self adjuster on the pedal release.
The park brake cables on this vehicle have an automatic self adjuster
built into the park brake pedal mechanism. When the foot operated park
brake pedal is in its released (upward most) position, a clock spring
automatically adjusts the park brake cables. The park brake cables are
adjusted (tensioned) just enough to remove all the slack from the
cables. The automatic adjuster system will not over adjust the cables
causing rear brake drag.
Due to the automatic adjust feature of the park brake pedal, adjustment
of the parking brake cables on these vehicles relies on proper drum
When the park brake pedal is applied the self adjuster is by-passed and the pedal operates normally to engage the park brakes.
When a service procedure needs to be performed on the park brake pedal
or the park brake cables, the automatic self adjuster can be manually
locked out by the service technician.
TRANSMISSION FLUID AND TRANSFER CASE FLUIDS ARE SUPPOSED TO BE CHANGED EVERY 60,000 MILES. ENGINE OIL AND FILTER SHOULD BE CHANGED EVERY 3,000 MILES, THESE ARE AUTOMOTIVE INDUSTRY STANDARDS I HAVE WORKED WITH FOR 35 YEARS
You are correct,the brakes are designed to self adjust when you back up, but this is After they have initially been adjusted after a brake job. You say you had to loosen the adjustment some to get the drums back on, this is normal, as the new brake shoes are thicker than the old worn ones. You are not wrong when you thought backing up the truck (and then applying the brakes) will adjust them. What is wrong with this though, is that you would probably have to back up and hit the brakes for a couple of hours if they are in need of quite a bit of adjustment, and that's if the adjusters are working perfectly. You really need to do an initial adjustment while the truck is still jacked up. The rubber grommets should be removed so you can adjust the brakes. It may be difficult to see the adjusters, but that's how you get to them. Do you have a brake adjusting tool? The slight bend in it makes it perfect for getting in the slot. Did you make sure the adjusting wheel is not seized up(or difficult to turn) while you had it apart? To adjust them just right, you can have the wheels on, truck jacked up, adjust and slowly spin the wheel. When you feel a very slight drag, it's adjusted properly. If you over adjust, you need to put a very thin screwdriver through the backing plate and hold the small metal piece that touches the adjusting wheel out and away from the wheel so you can back off on the adjustment. (this small plate is there to prevent the adjuster from loosening by only allowing it to turn in one direction, pushing the plate out of the way allows you to go in the opposite direction, to loosen the brake adjustment).
