Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely raise it using jack stands.
Wear safety goggles and gloves.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a socket set.
2. Unbolt the caliper using a socket or wrench and secure it to avoid hanging by the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Check the new brake pads for proper fit and install them into the bracket.

3. Inspect and Resurface/Replace Brake Rotors

Sub-steps:
1. Remove the brake rotor by unbolting it from the hub.
2. Inspect for warping or uneven surfaces using a dial indicator or straightedge.
3. If the rotor is within specifications, resurface it; otherwise, replace it with a new rotor.
4. Install the rotor back onto the hub, securing it with the appropriate torque using a torque wrench (typically 80-100 ft-lbs for Honda Civics).

4. Reassemble Brake Components

Sub-steps:
1. Reinstall the caliper over the new brake pads.
2. Tighten the caliper bolts to the manufacturer’s specification (usually around 20-25 ft-lbs).
3. Reinstall the wheel and lower the vehicle.

5. Bleed the Brake System

Sub-steps:
1. Locate the brake bleeder valve on each caliper.
2. Attach a clear hose to the bleeder valve and place the other end in a container.
3. Have an assistant pump the brake pedal several times and hold it down.
4. Open the bleeder valve slightly to release air bubbles and brake fluid, then close it before your assistant releases the pedal.
5. Repeat until no air bubbles appear, ensuring to keep the brake fluid reservoir topped up.
