Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Use wheel chocks to prevent rolling.

2. Remove the Wheel

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

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket set and slide the caliper off the rotor.
- Check the thickness of the brake pads; if they are below 3mm, replace them.
Replace Brake Pads:
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they fit snugly in place.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are scored or worn beyond acceptable limits, replace them.
Remove the caliper bracket by unscrewing the bolts.
Slide the rotor off the hub; if it’s stuck, gently tap it with a rubber mallet.
Install the new rotor, ensuring it is properly seated.

5. Reassemble Brake Components

Reattach the caliper bracket and torque the bolts to manufacturer specifications (usually around 79-100 ft-lbs).
Slide the caliper back over the new pads and secure it with the caliper bolts.
Reinstall the wheel and torque the lug nuts to the specified value (typically 76-80 ft-lbs).

6. Final Checks

Lower the vehicle and remove wheel chocks.
Pump the brake pedal several times to set the brake pads against the rotors.
