Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface with the parking brake engaged.
Wear safety gloves and goggles.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and suspend it with a bungee cord (do not let it hang by the brake line).
- Remove the old brake pads from the caliper bracket.
Replacement:
- Install new brake pads into the caliper bracket, ensuring they are correctly positioned.
- Lubricate the back of the new pads with brake grease to prevent squeaking.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are damaged:
- Remove the caliper bracket by unbolting it.
- Slide the rotor off the hub.
- Clean the hub surface before installing new rotors.
- Install new rotors, ensuring they are properly seated.

5. Reassemble Components

Reattach the caliper bracket and torque bolts to manufacturer specifications.
Reinstall the caliper over the new pads and torque the caliper bolts.
Reinstall the wheel and torque the lug nuts in a criss-cross pattern.
Lower the vehicle and ensure all tools are removed from the engine bay.
