Assuming Drum Brakes (Most Likely):
Tools You'll Need:
* Jack and jack stands (SAFETY FIRST: Always use jack stands, never rely solely on a jack)
* Lug wrench
* Wheel chocks
* Socket set (various sizes, including metric)
* Wrenches (various sizes, including metric)
* Hammer
* C-clamp or brake spring compressor tool (essential!)
* Wire brush
* Brake cleaner
* New brake shoes
* New wheel cylinders (highly recommended, even if they seem okay)
* New hardware (clips, springs, etc.) – get a kit specifically for your truck's year and model
* Grease
* Gloves
* Safety glasses
Procedure:
1. Safety First: Park on a level surface, engage the parking brake, chock the front wheels, and use jack stands to securely lift the rear of the truck. Never work under a vehicle supported only by a jack.
2. Remove the Wheel: Remove the lug nuts and carefully remove the wheel.
3. Remove the Drum: Often, the drum is simply held on by friction. You may need to gently tap the drum with a rubber mallet around its circumference to break it free. If it's really stuck, use a drum puller tool (available at auto parts stores).
4. Inspect Components: Once the drum is off, inspect everything thoroughly. Pay close attention to:
* Brake Shoes: Check for wear, scoring, or cracks.
* Wheel Cylinders: Check for leaks or damage. Leaking wheel cylinders are a common cause of rear drum brake failure and should be replaced.
* Return Springs: Check their condition and ensure they're not broken or bent.
* Adjusting Screw: Check its condition and operation.
5. Compress the Spring: This is the trickiest part. Use a C-clamp or a brake spring compressor tool to compress the springs holding the brake shoes in place. This is crucial for safety; improper compression can lead to injury. Refer to your repair manual or a YouTube video for your specific truck model to see how these springs are compressed.
6. Remove the Old Shoes: Once the springs are compressed, the old brake shoes should come out relatively easily.
7. Install the New Shoes: Install the new brake shoes, making sure they're properly seated and that all the springs and hardware are correctly installed according to your repair manual or a diagram. Pay very close attention to the orientation of each spring and clip.
8. Install New Wheel Cylinders (Recommended): If you're replacing the wheel cylinders, install the new ones, carefully following the instructions that come with them. Make sure to lubricate the seals properly.
9. Adjust the Brakes: Once everything is back together, use the adjuster to properly set the brake shoes. You will likely have to turn the adjusting screw to get the right amount of clearance. Refer to your repair manual for correct procedure.
10. Reinstall the Drum: Put the drum back on.
11. Reinstall the Wheel: Reinstall the wheel and tighten the lug nuts.
12. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
13. Test the Brakes: Before driving, pump the brake pedal several times to ensure the brakes are working correctly. Test drive carefully and ensure the brakes are responsive and stopping correctly.
Important Considerations:
* Repair Manual: Highly recommended. A factory service manual or a Haynes/Chilton manual will provide detailed instructions and diagrams specific to your vehicle.
* YouTube: Many helpful videos demonstrating rear drum brake replacement are available online. Search for "1997 Chevy K1500 rear drum brake replacement."
* Disc Brakes (Less Likely): If your truck has rear disc brakes, the procedure is much simpler and involves removing the caliper, replacing the pads, and reinstalling the caliper. The process is very similar to front disc brake replacement.
