Need a diagram of how a 83 chevy 3/4 ton, 4 wh. Drive rear drums come off to replace the brake shoes and brake cylinders.

wreckers or brake repair shops will have all that you want

Watch this video it should give you what you need.

Sounds like your brakes need bled or your vaccuum booster is getting ready to go.

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.

Copy and paste this into your search window: 2002 ford ranger rear brake diagram

You should see four pictures pop up, select the brake parts diagram or the brake picture.

there should be a rubber plug behind the drum and that way you can back off the shoes until the drum is free try these websites www.autozone.com and www.alldatadiy.com and that way you be able to get pictures and diagrams showing you how to repair your truck

Here is the diagram,It is always a good idea to only disaasemble one side so you can use the other side as a reference,I also reccomend using a set od brake pliers,they will the disassembly and reassembly much easier.

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 .

The rear drum brakes:

• Have internal shoes that expand against the brake drum (1126).
• Are a single-anchor type.
• Are actuated by one rear wheel cylinder (2262).
• Have two pistons in the rear wheel cylinder (2261). One exerts force against the upper end of the primary shoe; the other exerts force against the upper end of the secondary shoe.
• Adjust rear brake shoes and linings (2200) automatically.
• Need manual brake adjustment if the adjusters are not operating properly or after the rear brake shoes and linings have been replaced.

When the brake pedal is applied, hydraulic fluid pressure forces the pistons in the rear wheel cylinder outward, moving the rear brake shoes and linings against the brake drum.
The rear drum brake system includes the parking brake mechanism. Refer to Section 206-05 .
