Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Socket set
- Brake cleaner
- Torque wrench
- Caliper tool (for compressing pistons)
- Safety goggles and gloves
Safety Warnings:
- Ensure the vehicle is on a flat surface and securely supported with jack stands before working on it.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Brake Caliper

Use a socket set to remove the caliper bolts.
Carefully slide the caliper off the rotor and hang it using a bungee cord or wire to avoid stress on the brake line.

4. Inspect and Replace Brake Pads

Check the brake pads for wear. If they are worn down, remove the old pads.
Apply brake grease to the back of the new pads to prevent noise.
Install the new brake pads into the caliper bracket.

5. Inspect and Replace Rotors (if necessary)

If the rotors are damaged, remove them by unscrewing the retaining screws (if equipped) and sliding them off the hub.
Clean the hub surface with brake cleaner before installing new rotors.
Install the new rotors, ensuring they are seated properly.

6. Reinstall Caliper

Use the caliper tool to compress the caliper piston back into the caliper housing to accommodate the new pads.
Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer's specifications.

7. Reinstall Wheel

Place the wheel back onto the hub.
Hand-tighten the lug nuts and lower the vehicle.
Once on the ground, torque the lug nuts to the manufacturer’s specifications.
