Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves for protection.

2. Raise the Vehicle

Use a jack to lift the vehicle off the ground.
Secure it with jack stands to prevent any accidents.

3. Remove the Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the braking components.

4. 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 glazing on the pads.
Replace Brake Pads:
- Remove the caliper retaining bolts using a socket set.
- Slide the caliper off the rotor and support it without straining the brake line.
- Remove old pads and install new ones, ensuring they are seated properly.
- Reattach the caliper and tighten the retaining bolts to the manufacturer's torque specifications (typically around 25-35 ft-lbs).

5. Inspect and Replace Brake Rotors (if needed)

Inspect Rotors:
- Check for deep grooves, scoring, or warping.
Replace Rotors:
- If replacement is necessary, remove the caliper bracket.
- Slide the rotor off the hub and install a new rotor, ensuring it is properly aligned.
- Reattach the caliper bracket and tighten the bolts to specifications.

6. Reassemble and Lower the Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts in a crisscross pattern to the manufacturer's specifications (typically 80-100 ft-lbs).
