Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Remove Wheel

Use a jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts with a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads; if less than 3mm, replace them.
- Look for uneven wear or damage.
Replace Brake Pads:
- Remove caliper bolts using 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 seated correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Check Rotors:
- Measure rotor thickness with a micrometer; replace if below specs.
- Look for grooves or scoring.
Replace Rotors:
- Remove caliper bracket bolts and take off the caliper bracket.
- Remove the rotor.
- Install new rotor, ensuring it is seated properly against the hub.

5. Reassemble and Test

Reattach the caliper and caliper bracket, tightening bolts to manufacturer specifications (typically around 25-35 ft-lbs).
Reinstall the wheel and tighten lug nuts in a star pattern.
Lower the vehicle and reconnect the battery.
