Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery for safety.

2. Remove Wheel

Tools Required: Lug wrench, jack, jack stands.
Loosen the lug nuts slightly while the car is on the ground.
Raise the vehicle with a jack and securely place jack stands under the vehicle.
Remove the wheel completely.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor; support it with a bungee cord to avoid strain on the brake line.
Remove the old brake pads; check for uneven wear.
Tools Required: Torque wrench, brake pad spreader.
Install new brake pads, ensuring they are seated properly.
Reinstall the brake caliper and torque bolts to manufacturer specifications (typically 20-30 ft-lbs).

4. Inspect and Replace Rotors (if necessary)

If rotors are scored or warped, remove them by unscrewing the retaining screws.
Clean the hub surface to ensure proper seating of the new rotor.
Install new rotors, ensuring they are aligned properly.
Reinstall the wheel and hand-tighten lug nuts.

5. Final Assembly

Lower the vehicle off the jack stands.
Tighten the lug nuts to the specified torque (typically 80-100 ft-lbs).
Reconnect the battery.
