Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety goggles.
Raise the vehicle using the jack and secure it with jack stands.
Remove the front wheels using the lug wrench.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using the socket set.
2. Carefully slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper for any damage or sticking components.
5. If brake pads are worn below the manufacturer’s specifications (usually 3mm or less), replace them with new pads.
6. Apply brake grease to the backing of the new pads to prevent future squeaking.

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotor surface for grooves or scoring; replace if damaged.
2. If rotors need replacement, remove the caliper bracket by unscrewing the bolts.
3. Remove the rotor from the hub. You may need to tap it gently with a hammer.
4. Install the new rotor onto the hub, ensuring it’s seated correctly.
5. Reinstall the caliper bracket and torque the bolts to the manufacturer's specifications.

4. Reassemble and Test

Sub-steps:
1. Reinstall the caliper over the new pads and torque the caliper bolts to manufacturer specifications.
2. Reattach the wheels and lower the vehicle.
3. Pump the brake pedal a few times to seat the pads against the rotors.
4. Test drive the vehicle to ensure proper brake function and listen for any further noise.
