Adjusting Drum Brakes (Rear):
The most common adjustment is for the rear drum brakes, as these are self-adjusting but can sometimes need manual intervention. This is typically done through access holes on the backing plates.
1. Locate the adjuster: You'll find a starwheel adjuster on the backing plate of each rear wheel. Access it through the hole usually covered by a rubber plug or cap.
2. Turn the adjuster: Use a screwdriver or a special starwheel adjuster tool (available at auto parts stores). Turn the adjuster clockwise to tighten the brakes and counterclockwise to loosen them. Important: Turn it very slightly (1/8th to 1/4th of a turn at a time).
3. Check for pedal feel: After each adjustment, pump the brake pedal several times and check the pedal travel. You want firm pedal with minimal travel. If the pedal goes almost to the floor, the brakes are too loose. If the pedal is very hard to push, the brakes are too tight.
4. Repeat: Adjust until you achieve the proper pedal feel. It’s a process of trial and error. Do not over-tighten.
Adjusting Drum Brakes (Front):
Front drum brakes are adjusted similarly, if equipped. Access the starwheel adjuster through the backing plate hole. Follow the same steps as the rear brakes above.
Adjusting Disc Brakes (Front - if applicable):
If your Coronet has front disc brakes, you *don't* adjust the pads directly like you do with drums. The adjustment is usually automatic via the caliper pistons. However, you might need to:
1. Check the brake pads: Ensure the pads have sufficient thickness. Worn pads need to be replaced, not adjusted.
2. Check the caliper: Inspect the caliper for damage or binding. A sticking caliper piston will cause problems and might need repair or replacement.
Important Considerations:
* Safety First: Always work on your brakes in a safe, level area. Use jack stands to support the vehicle properly. Never work under a car supported only by a jack.
* Brake Fluid: Check your brake fluid level regularly. Low fluid is a serious problem.
* Wheel Cylinders: Leaking wheel cylinders will require replacement, not just adjustment.
* Professional Help: If you're uncomfortable working on your brakes, it's best to take your car to a qualified mechanic. Brake systems are critical for your safety.
* Shop Manual: A 1967 Dodge Coronet shop manual will provide detailed diagrams and instructions specific to your vehicle. This is highly recommended.
This information is for guidance only. Always refer to your owner's manual or a shop manual for specific instructions and safety precautions related to your particular 1967 Dodge Coronet. Improper brake adjustment can lead to dangerous driving conditions.
