Solution

1. Preparation

Tools Required: OBD-II scanner, brake fluid, socket set, torque wrench, brake cleaner, safety goggles, gloves.
Disconnect the negative terminal of the battery to avoid electrical shorts.

2. Addressing Error Codes

Clear Error Codes:
- Use the OBD-II scanner to clear the retrieved error codes and reset the system.
Inspect and Repair:
- If codes reappear, proceed to inspect components indicated by the codes (e.g., ABS module, wheel speed sensors).
- Replace any faulty components identified during the inspection.

3. Brake Fluid Check and Replacement

Check Fluid Level:
- Remove the cap from the brake master cylinder and check fluid level.
Replace Fluid:
- If low or contaminated, suction out the old fluid and refill with manufacturer-specified brake fluid (usually DOT 3 or DOT 4).
Bleed Brakes:
- Bleed the brake system to remove any air bubbles. Start from the furthest wheel from the master cylinder and work towards the closest.

4. Brake Pad Inspection and Replacement

Remove Wheel:
- Use the socket set to remove the lug nuts and take off the wheel.
Inspect Brake Pads:
- Check the thickness of the brake pads. If they are below the minimum thickness (usually around 3mm), replace them.
Replace Brake Pads:
- Remove the caliper bolts, slide off the caliper, and replace the pads. Ensure to apply brake grease to the backing of the new pads.
Reassemble:
- Reinstall the caliper and torque bolts to the manufacturer's specifications.

5. Final Checks

Reconnect the battery terminal.
Test the brake system by pressing the pedal and checking for firmness.
