Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves.

Tools Required: Jack, jack stands, lug wrench
Sub-steps:
1. Loosen the lug nuts slightly while the wheel is on the ground.
2. Use the jack to lift the vehicle and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Tools Required: Torque wrench, inspection mirror
Sub-steps:
1. Inspect the brake pads for thickness; replace if worn below specifications (usually 3mm).
2. Check brake rotors for any deep grooves or scoring; replace if necessary.
3. Examine calipers for proper movement; clean and lubricate slides if sticking is found.

4. Replace Brake Pads and Rotors (if needed)

Tools Required: Ratchet, socket set, brake cleaner
Sub-steps:
1. Remove the caliper bolts and gently slide the caliper off.
2. Remove old brake pads from the caliper bracket.
3. If rotors are to be replaced, remove the rotor retaining screws and pull the rotor off.
4. Install new rotors (if applicable), ensuring they are properly seated.
5. Install new brake pads in the caliper bracket, applying brake grease where needed.
6. Reinstall the caliper and torque bolts to manufacturer specifications.

5. Reassemble and Lower Vehicle

Tools Required: Torque wrench
