Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Gather necessary safety equipment (gloves, goggles).

2. Lift Vehicle

Use a jack to lift the front or rear of the Civic, depending on which brakes are affected.
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Store lug nuts in a safe location for reinstallation.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts with a socket wrench.
- Carefully slide the caliper off the rotor, supporting it to avoid stress on the brake line.
- Check the thickness of the brake pads; if they are worn below 3mm, they should be replaced.
Replace Brake Pads:
- Remove the old brake pads from the caliper bracket.
- Clean the caliper bracket with brake cleaner.
- Install new brake pads into the bracket, ensuring proper orientation.

5. Inspect and Replace Rotors (if necessary)

If rotors are worn or warped, they need replacement:
- Remove the rotor by unscrewing retaining screws and sliding it off the hub.
- Install new rotors, ensuring they are properly aligned and secured.

6. Reassemble Components

Reattach the caliper over the new brake pads and tighten caliper bolts to manufacturer specifications (typically 20-25 ft-lbs).
Reinstall the wheel and hand-tighten lug nuts.

7. Lower Vehicle and Test

Carefully lower the vehicle back to the ground using the jack.
Tighten lug nuts to the manufacturer’s torque specifications (usually 80-100 ft-lbs).
Pump the brake pedal to seat the pads against the rotor before driving.
