Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, brake cleaner, and safety glasses.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues while working on the brakes.

2. Remove Wheel

Loosen the lug nuts using a lug wrench.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Examine the brake pads for wear; if they are less than 3mm thick, replace them.
2. If replacing, remove the caliper by unscrewing the caliper bolts.
3. Slide out the old brake pads.
4. Apply brake grease to the backing of the new pads to reduce noise.
5. Install the new brake pads in the caliper.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotor surface for scoring; if uneven, replace them.
2. Remove the caliper bracket by unscrewing the bolts.
3. Slide off the rotor and clean the hub surface with brake cleaner.
4. Install the new rotor, ensuring it sits flat.
5. Reinstall the caliper bracket and torque bolts to manufacturer's specifications.

5. Reassemble and Final Checks

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the specified torque rating.
Reconnect the battery.
