Disconnect the scanner after clearing the codes.

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Remove the wheel using a socket set.
- Inspect the brake pads for thickness; replace if less than 3mm.
- Use a torque wrench to tighten the wheel bolts to manufacturer specifications after reassembly.
Inspect Brake Rotors:
- Check for warping or grooves on the rotors. Replace if necessary.
- If machining is needed, follow proper procedures for rotor resurfacing.
Replace Brake Fluid:
- Locate the brake fluid reservoir and check the fluid condition. If contaminated, perform a brake fluid flush.
- Use a brake bleeder kit to remove old fluid and replace it with the specified brake fluid type (DOT 3 or DOT 4 as per owner's manual).

4. Test Drive

After completing the repairs, take the vehicle for a test drive.
Ensure the brakes are functioning correctly and monitor for any warning lights.
