Here's a general overview. This is not a complete, step-by-step guide and should not be considered a substitute for a proper repair manual:
Tools You'll Likely Need:
* Jack and jack stands: Essential for safety. Never work under a car supported only by a jack.
* Wheel chocks: To prevent the car from rolling.
* Lug wrench: To remove the wheels.
* Hammer: For tapping things loose.
* Socket wrench set: Various sizes, including metric.
* Screwdrivers (Phillips and flathead): Possibly needed depending on the specific brake hardware.
* C-clamp or brake spring compressor tool: Crucial for compressing the brake springs. A poorly designed compressor can damage the springs, so be cautious.
* Wire brush: To clean brake parts.
* Brake cleaner: To remove grease and debris.
* New brake shoes, wheel cylinders, and hardware kit: Always replace these as a set. Don't reuse old parts.
* Grease: Use brake grease only where specified in your repair manual.
* Gloves: To protect your hands.
* Safety glasses: To protect your eyes.
General Steps (Drum Brakes):
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 vehicle.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Remove the Drum: The brake drum might be stuck on due to rust. Gently tap around the circumference with a rubber mallet to break it loose. Sometimes penetrating oil helps.
4. Inspect the Components: Once the drum is off, inspect the brake shoes, wheel cylinder, springs, and other hardware. Look for wear, rust, damage, or leaks. Replace everything that looks worn or questionable.
5. Compress the Brake Springs: This is the most challenging part. Use the C-clamp or spring compressor tool to carefully compress the springs holding the brake shoes in place. Be extremely careful not to break the springs. The springs are under significant tension.
6. Remove the Old Brake Shoes: Once the springs are compressed, remove the old brake shoes.
7. Install the New Brake Shoes: Install the new brake shoes, ensuring they're properly seated.
8. Reassemble the Brake System: Carefully release the spring compressor, ensuring the springs are correctly seated and the shoes are properly adjusted. This is critical for proper braking. If you are unsure of the correct configuration, consult a repair manual.
9. Install the Wheel Cylinder: If necessary replace the wheel cylinder. It usually sits between the two brake shoes.
10. Adjust the Brake Shoes: This is often done automatically by the self-adjusting mechanism but may require manual adjustment using the star wheel. Consult your repair manual.
11. Install the Drum: Put the drum back on. It should slide on easily.
12. Replace the Wheel: Tighten the lug nuts, but don't overtighten them yet.
13. Lower the Vehicle: Lower the vehicle to the ground.
14. Torque Lug Nuts: Tighten the lug nuts to the manufacturer's specified torque.
15. Test the Brakes: Pump the brake pedal several times to build up pressure and check for leaks. Then, test the brakes carefully in a safe, controlled environment at low speeds.
Important Notes:
* Bleeding the Brakes: After replacing the wheel cylinders, you might need to bleed the brakes to remove any air that got into the brake lines. This requires two people and a wrench.
* Repair Manual: A repair manual specific to your 1994 Dodge Spirit is invaluable for detailed instructions, torque specifications, and diagrams.
* Safety: Always prioritize safety. If you're not comfortable performing this repair, take your car to a qualified mechanic. Improperly installed brakes can be extremely dangerous.
This is a simplified overview. Again, consult a repair manual specific to your 1994 Dodge Spirit before attempting this repair. Failure to follow proper procedures could result in brake failure, which is extremely dangerous.
