Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Wear safety glasses and gloves.

2. Scan for Codes

Use an OBD-II scanner to retrieve brake-related DTCs (Diagnostic Trouble Codes).
Note the specific codes for further analysis.

3. Inspect Brake Components

Brake Pads and Rotors:
- Remove the wheel using a socket set.
- Inspect the brake pads for thickness; replace if worn below the manufacturer's specifications.
- Measure rotor thickness; replace if below the minimum requirement.
Brake Fluid:
- Check fluid level; top off with the recommended brake fluid (DOT 3 or DOT 4 as specified).
- If contaminated, perform a brake fluid flush.

4. Test Electronic Components

ABS Module:
- Inspect wiring and connectors for damage.
- Use a multimeter to test the ABS module's power and ground connections.
Wheel Speed Sensors:
- Inspect for obstructions or damage.
- Measure sensor output to ensure proper functioning.

5. Brake Line Inspection

Visually inspect brake lines for leaks, cracks, or corrosion.
Use a brake line inspection tool if necessary to check for internal blockages.

6. Reassemble and Test

Reinstall wheels and torque lug nuts to manufacturer specifications.
Test the brake system by performing a short drive to evaluate braking performance.
