Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Wear safety gloves and goggles.

2. Clear Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Use the scanner to clear any stored error codes.
Turn the ignition off and then restart the vehicle to check if the codes reappear.

3. Brake Fluid Inspection and Replacement

Inspect the Brake Fluid:
- Open the hood and locate the brake fluid reservoir.
- Check fluid level; if low, top off with the manufacturer-recommended brake fluid.
Replace Brake Fluid:
- If fluid is dark or contaminated, perform a brake fluid flush.
- Locate the brake bleeder valves on all four brake calipers.
- Attach a clear hose to the bleeder valve and submerge it in a container.
- Have an assistant pump the brake pedal while you open the bleeder valve to release old fluid.
- Close the valve once clear fluid appears; repeat for each caliper until new fluid flows.

4. Brake Pad and Rotor Replacement

Remove Wheel:
- Loosen lug nuts, lift the vehicle using a jack, and secure with jack stands.
- Remove the wheel to access the brake assembly.
Inspect and Replace Pads and Rotors:
- Remove caliper bolts and slide the caliper off the rotor.
- Check the pads; if worn below the minimum thickness, replace them.
- Measure rotor thickness; if below specification, replace rotors.
- Reinstall new pads and rotor, ensuring everything is torqued to manufacturer specifications.

5. ABS Sensor Inspection and Replacement

Inspect ABS Sensors:
- Locate the ABS sensors on each wheel hub.
- Clean any dirt or debris from the sensor area.
- Check wiring for visible damage; replace sensors if faulty.

6. Final Assembly and Test

Reinstall the wheel and lower the vehicle.
Tighten lug nuts to the specified torque.
Start the vehicle and perform a test drive to ensure the brakes engage smoothly.
