Tools You'll Need:
* Wheel chocks: Essential for safety.
* Lug wrench: To remove the wheel.
* Jack and jack stands: To safely lift the vehicle.
* Hammer: May be needed to break loose stubborn parts.
* Socket wrench set: Various sizes, including one to fit your wheel lug nuts.
* Screw driver: Possibly a flathead and/or Phillips head.
* Brake drum puller: Highly recommended to avoid damage. A slide hammer type is ideal.
* Wrench for wheel studs: To help remove the studs if they’re seized in the drum.
* Wire brush: To clean rust and debris.
* Penetrating oil (like PB Blaster): To loosen seized parts.
* New brake drums: Obviously! Make sure you get the correct ones for your Coronet.
* Gloves: Protect your hands.
* Safety glasses: Protect your eyes.
Procedure:
1. Safety First: Chock the rear wheels securely. Raise the front of the vehicle using a jack and secure it on jack stands. Never work under a vehicle supported only by a jack.
2. Remove the Wheel: Use your lug wrench to remove the lug nuts from the wheel. Keep them organized. Remove the wheel.
3. Prepare for Drum Removal: Liberally apply penetrating oil to the area where the brake drum meets the wheel hub. Let it soak for at least 15-20 minutes.
4. Remove the Brake Drum: This is often the trickiest part. If the drum doesn't slide off easily after tapping gently with a hammer, use a brake drum puller. This tool is specifically designed to remove drums without damaging them. Avoid hitting the drum directly with a hammer as you can damage it.
5. Dealing with Stuck Lug Bolts/Studs: If the wheel studs are stuck in the drum, you'll need to carefully work them loose. A penetrating oil and a wrench are often sufficient. If they're severely rusted, you may need to use heat (carefully!) or more aggressive methods, but this can easily damage the drum or studs. If the studs are damaged, they'll likely need replacing.
6. Inspect the Brake Shoes and Hardware: Once the drum is off, inspect the brake shoes and other components for wear and tear. Replace any worn or damaged parts.
7. Install the New Brake Drum: Simply slide the new brake drum onto the wheel studs. It should fit smoothly.
8. Reassemble: Replace the wheel, tighten the lug nuts to the manufacturer's specified torque (consult your repair manual). Lower the vehicle.
9. Test the Brakes: After reinstalling everything, test the brakes thoroughly. A road test is essential to ensure they are functioning correctly.
Important Considerations:
* Rust and Corrosion: On a 1966 vehicle, rust and corrosion are likely. Penetrating oil is your friend! Be patient and allow it sufficient time to work.
* Damaged Studs: If the studs are broken or badly damaged during removal, you'll need to replace them. This requires some mechanical skill and the correct tools.
* Brake Adjustment: After replacing the drums, you may need to adjust the brakes. This usually involves adjusting the star wheel mechanism on the backing plate. Again, your repair manual will guide you through this.
This is a general guide. Always consult a repair manual specific to your 1966 Dodge Coronet for detailed instructions and torque specifications. If you're not comfortable performing this repair yourself, take it to a qualified mechanic. Brake work is crucial for safety; don't take unnecessary risks.
