Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Safety warning: Disconnect the battery before working on the braking system to avoid accidental activation.

2. Remove Wheel

Loosen the lug nuts with a socket wrench but do not completely remove them.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor; do not let it hang by the brake line.
Inspect the brake pads for wear; if they are less than 3mm thick, replace them.
If replacing, remove the old brake pads and install new pads, ensuring they are oriented correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for scoring or warping. If damaged, proceed to replace.
To remove the rotor, unscrew the retaining screws (if applicable) and pull the rotor off the hub.
Install the new rotor, ensuring it is properly seated.

5. Reassemble Braking Components

Reattach the brake caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer’s specified torque (usually around 25-35 lb-ft for Honda).
Reinstall the wheel, hand-tighten the lug nuts, and lower the vehicle.

6. Final Checks

Reconnect the battery.
Pump the brake pedal several times to ensure proper pad seating and restore brake pressure.
Check brake fluid levels and top off if necessary.
