Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, torque wrench, socket set, C-clamp, and a caliper tool.
Safety Warnings: Ensure the vehicle is on a level surface and secured with wheel chocks before lifting. Wear safety glasses and gloves.

2. Lift the Vehicle

Loosen the lug nuts on the wheels where brake pads will be changed.
Use the jack to lift the vehicle and place it securely on jack stands.
Remove the wheels.

3. Remove Brake Components

Remove the caliper mounting bolts using the appropriate socket size.
Carefully slide the caliper off the rotor. Do not disconnect the brake line.
Secure the caliper with a bungee cord or rope to avoid putting strain on the brake line.
Remove the brake pads from the caliper bracket.

4. Inspect and Replace Components

Inspect the brake rotor for uneven wear or warping; replace if necessary.
If the caliper is found to be sticking, it may need to be rebuilt or replaced.
Clean the caliper bracket and ensure the slides are free of debris and lubricated.
Install new brake pads, ensuring they are the correct type for the vehicle.

5. Reassemble and Torque

Reattach the caliper over the new brake pads and rotor.
Tighten the caliper mounting bolts to the manufacturer's specified torque (usually around 20-25 ft-lbs for Honda).
Reinstall the wheels and hand-tighten the lug nuts.

6. Lower the Vehicle and Finish

Lower the vehicle back to the ground.
Tighten the lug nuts to the specified torque (typically 80-100 ft-lbs).
Pump the brake pedal several times to ensure proper pad seating.
