Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear appropriate personal protective equipment (PPE), such as gloves and safety goggles.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts on the affected wheel using a socket set.
2. Raise the vehicle with a jack and secure it on jack stands.
3. Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Locate the brake caliper and remove the caliper mounting bolts with a socket wrench.
2. Carefully slide the caliper off the brake rotor and support it using a bungee cord or similar tool to avoid strain on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper slides and ensure they move freely; lubricate with brake grease if necessary.
5. Install new brake pads (ensure they are the correct fit for your Honda Pilot).
6. Reattach the caliper over the new pads and secure it with the mounting bolts to the manufacturer's torque specifications.

4. Inspect and Resurface/Replace Rotors

Sub-steps:
1. Check the brake rotors for scoring or excessive wear; use a micrometer to measure rotor thickness.
2. If resurfacing is needed, take the rotors to a machine shop or use a brake lathe if available.
3. If rotors are too worn, replace them with new ones.
4. Clean the rotor surface with brake cleaner before installation.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands and fully tighten the lug nuts in a crisscross pattern to the specified torque.
3. Pump the brake pedal several times to reset the brake system before driving.
