Tools You'll Need:
* Jack and jack stands (essential for safety)
* Wheel chocks
* Lug wrench
* Socket set (metric) – likely need 13mm, 15mm, and possibly others
* Wrench for caliper bolts (likely 14mm or 15mm)
* C-clamp or brake caliper compressor tool
* Brake cleaner
* New rear brake shoes and hardware kit (including springs, clips, and self-adjusters)
* New brake drums (if needed – inspect for scoring or excessive wear)
* Penetrating oil (like PB Blaster)
* Safety glasses
* Gloves
Procedure:
1. Safety First: Park the Cavalier on a level surface, engage the parking brake, and chock the front wheels. Use jack stands to securely lift the rear of the vehicle, ensuring the vehicle is stable. Never work under a vehicle supported only by a jack.
2. Remove the Wheel: Loosen the lug nuts with the lug wrench before jacking up the vehicle. Then, remove the wheel and set it aside.
3. Inspect the Brake Drum: Inspect the brake drum for scoring, cracks, or excessive wear. If it's damaged, replace it. If it's reusable, carefully remove it. Sometimes, it can be stubborn, and you might need to use a rubber mallet to tap it off. Be careful not to damage the drum or the wheel studs.
4. Remove the Brake Shoes: Once the drum is off, you'll see the brake shoes. Note the position and arrangement of all the springs, clips, and self-adjuster mechanism. Take photos if it helps. Carefully remove these components, noting their location. Use penetrating oil if anything is stuck.
5. Inspect the Brake Shoes and Hardware: Inspect the brake shoes for wear. If the lining is worn down to the rivets, or if the shoes are damaged, replace them. Replace any rusty or damaged hardware as part of the kit.
6. Install the New Brake Shoes: Install the new brake shoes, carefully placing them in their correct positions. Reinstall all springs and clips in their original locations, referring to your notes or photos. Make sure everything is seated properly. The self-adjuster mechanism usually requires adjustment – this is often done via a small ratchet-like component on the brake shoe.
7. Adjust the Self-Adjuster: This step is important to ensure proper brake operation. Refer to your vehicle's repair manual for the correct procedure for your specific self-adjuster mechanism. Often, rotating the star wheel on the self-adjuster will ensure the shoes make proper contact with the drum.
8. Install the Brake Drum: Carefully slide the brake drum back onto the wheel studs. Make sure it spins freely but with good contact from the shoes. If it's too tight, you may need to readjust the self-adjuster.
9. Reinstall the Wheel: Put the wheel back on, tightening the lug nuts in a star pattern (opposite nuts). Don't fully tighten them yet.
10. Lower the Vehicle: Lower the vehicle to the ground. Now, fully tighten the lug nuts.
11. Check the Brake Pedal: Pump the brake pedal several times to ensure the brakes are working properly.
12. Repeat for the Other Side: Repeat the process for the other rear wheel.
13. Test Drive: After completing both sides, test drive the vehicle to ensure the brakes are functioning correctly. If you feel any unusual vibrations or noises, it may be necessary to recheck your work.
Important Considerations:
* Brake fluid: This job doesn't usually require brake fluid changes, but it's a good idea to check the brake fluid level in the master cylinder reservoir and top it off if needed. Never remove the reservoir cap while working on the brakes.
* Professional help: If you're not comfortable performing this repair yourself, it's always best to take your car to a qualified mechanic. Brake repair is crucial for safety.
* Repair manual: The information above is general. Consult a repair manual specific to your 1998 Chevy Cavalier for detailed instructions and torque specifications.
Remember, safety is paramount. If you're unsure about any step, seek professional assistance. Improper brake repair can be extremely dangerous.
