Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, torque wrench, OBD-II scanner.
Safety Warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged. Disconnect the battery before working on electrical components.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel using a lug wrench.
3. Inspect the brake pads for thickness; if they are below 3mm, replace them.
4. Remove the caliper by unscrewing the caliper bolts with a socket set.
5. Slide the caliper off the rotor and support it without stressing the brake line.
6. Remove the old brake pads from the caliper bracket.
7. Install new brake pads, ensuring they are seated correctly.
8. Reinstall the caliper and torque the caliper bolts to manufacturer specifications.

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. If rotors show significant wear or damage, remove them by unscrewing the rotor retaining screws (if applicable).
2. Clean the hub surface with brake cleaner to remove any rust or debris.
3. Install new rotors, ensuring they are properly aligned.
4. Reinstall any retaining screws and torque to specifications.

4. Brake System Inspection

Sub-steps:
1. Check the brake fluid level in the master cylinder; top off with manufacturer-recommended brake fluid if low.
2. Inspect the caliper for proper movement; clean any debris and lubricate sliding pins if necessary.
3. Test drive the vehicle gently to assess for noise reduction.
