Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, jack and jack stands, multimeter, brake fluid.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Address Fault Codes

Clear Existing Codes:
- Use the OBD-II scanner to clear the trouble codes after noting them.
- This helps in identifying if the codes return after repairs.
Inspect and Replace Components:
- If specific codes indicate faulty components (e.g., ABS sensor, brake pads):
  - Remove the wheel using the socket set.
  - Inspect the brake pads for wear; replace if below 3mm thickness.
  - Check the brake rotors for scoring; replace if necessary.

3. Brake Fluid Replacement

Flush Old Brake Fluid:
- Locate the brake fluid reservoir, remove the cap, and suck out old fluid using a turkey baster.
- Fill with new brake fluid as per manufacturer specifications (DOT 3 or DOT 4).
Bleed the Brake System:
- Start with the wheel furthest from the master cylinder. Open the bleeder valve while someone gently presses the brake pedal.
- Close the valve before releasing the pedal. Repeat until clear fluid flows without bubbles.

4. Electrical Connections

Inspect Wiring and Sensors:
- Check the wiring harness for frayed wires or loose connections.
- Use a multimeter to test voltage and continuity at the brake sensors.
- Repair or replace damaged wiring as necessary.

5. Reassemble and Test

Reinstall the wheel and lower the vehicle from the jack stands.
Reconnect the negative battery terminal and perform a road test to verify the brakes function correctly.
