Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface.
Use wheel chocks to prevent movement.
Disconnect the battery for safety if working on electronic brake systems.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure with jack stands.
Completely remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads; replace if less than 3mm.
- Look for uneven wear patterns.
Replace Brake Pads:
- Remove the caliper bolts with a socket set.
- Carefully slide the caliper off the rotor.
- Remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are oriented correctly.
- Reinstall the caliper over the new pads and tighten the caliper bolts to manufacturer specifications (typically around 20-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are scored or warped, they may need replacing.
Remove the caliper bracket by unscrewing the bolts.
Slide the rotor off the hub and replace it with a new rotor.
Torque the caliper bracket bolts to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground and tighten the lug nuts to the proper torque specification (typically 75-100 ft-lbs).
Reconnect the battery if it was disconnected.
Press the brake pedal a few times to seat the pads against the rotor.
