To compress the wheel cylinders in the rear drum brakes of a 2006 Civic (or any car with rear drum brakes), you need a drum brake adjuster. These tools come in a few forms:
* Star wheel adjuster: This is the most common type. It's a tool with a series of notches that engage the star-shaped adjuster mechanism inside the drum. You turn it to wind the wheel cylinder's shoes outward, effectively compressing them. This is the most likely type you'll need for a Civic.
* C-clamp method (not recommended): While you *could* theoretically use a C-clamp to carefully push the shoes back, it's risky. It's very easy to damage the wheel cylinder or shoes with this method, and it doesn't adjust the star wheel correctly. Avoid this if possible.
Procedure (using a star wheel adjuster):
1. Remove the wheel: Loosen the lug nuts before jacking up the car and properly supporting it on jack stands. Remove the wheel.
2. Access the adjuster: Locate the access hole for the star wheel adjuster. This is usually on the back of the drum. Sometimes you can access it without removing the drum, other times you may need to remove the drum (this is more involved).
3. Use the star wheel adjuster: Insert the correct tool into the access hole and carefully turn it clockwise (usually) to wind the adjuster and compress the shoes. You'll feel resistance as the shoes move. Do not force it.
4. Reinstall the drum and wheel: Once the shoes are compressed enough to allow the drum to slip back on, reinstall the drum, and then the wheel and lug nuts. Torque the lug nuts to the manufacturer's specified torque value.
Important Considerations:
* Consult a repair manual: A repair manual specific to your 2006 Honda Civic will provide detailed instructions and diagrams. This is crucial to avoid damage.
* Safety: Always work safely, using jack stands and ensuring the vehicle is properly supported.
* Brake fluid: Working on the brakes might require bleeding the brakes afterward to remove any air introduced into the system. This is best done with a helper.
* If unsure: If you're uncomfortable working on brakes, it's best to take your car to a qualified mechanic. Brake work is crucial for safety.
The process varies slightly depending on the exact model of your 2006 Civic (sedan, coupe, etc.), so again, a repair manual is highly recommended. A visual guide from a YouTube video of someone working on the same model would also be very helpful.
