1. Loosen lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle with a jack, then secure with jack stands.
3. Remove lug nuts and take off the wheel.

3. Inspect Brake Components

Tools Required: Torque wrench, caliper tool
Sub-steps:
1. Remove the caliper by unscrewing the mounting bolts.
2. Take off the brake pads and inspect for uneven wear.
3. Check rotor surface; replace if warped or severely scored.
4. Inspect caliper slides for corrosion or binding; lubricate as necessary.

4. Replace or Adjust Components

Tools Required: Brake pad spreader, fluid funnel
Sub-steps:
1. Replace worn brake pads with new ones, ensuring they are the same size and type.
2. If rotors are replaced, install new rotors and torque to manufacturer specifications.
3. Reassemble caliper and secure it with the appropriate torque.
4. Adjust or replace caliper slides if necessary to ensure free movement.

5. Reassemble and Reinstall Wheel

Tools Required: Lug wrench
Sub-steps:
1. Place the wheel back on and hand-tighten the lug nuts.
2. Lower the vehicle from jack stands and torque the lug nuts to manufacturer specifications.
