Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Raise the vehicle using a jack and support it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Remove the wheel from the hub to access the brake components.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the brake pads and hang it using a bungee cord (do not let it hang by the brake line).
- Remove the old brake pads from the caliper bracket.
- Compare the thickness of the old pads with the new ones; replace if worn below manufacturer specifications.
- Apply brake grease to the back of the new pads to prevent squeaking.
- Install the new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- If the rotors are scored or warped, remove the caliper bracket by unbolting it.
- Slide the rotor off the hub. If it’s stuck, use a rubber mallet to gently tap it loose.
- Clean the new rotor with brake cleaner to remove any protective oil.
- Install the new rotor onto the hub, ensuring it fits snugly.
- Reattach the caliper bracket and torque the bolts to manufacturer specifications.

5. Reassemble and Test

Sub-steps:
- Reinstall the brake caliper over the new pads and tighten the caliper bolts.
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the specified value using a torque wrench.
- Pump the brake pedal a few times to seat the pads against the rotor.
- Test drive the vehicle at low speeds to ensure proper brake function.
