Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Retrieve and Analyze Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the ON position without starting the engine.
Retrieve and note any brake-related error codes.
Consult the service manual for specific code definitions.

3. Inspect and Replace Brake Fluid

Check the brake fluid level; if low, top it up with the recommended fluid (DOT 3 or DOT 4).
If the fluid is dirty or contaminated, perform a brake fluid flush:
- Open the brake bleeder valve on each brake caliper starting from the farthest from the master cylinder.
- Pump the brake pedal until clean fluid emerges, then close the valve.
- Repeat until all calipers are flushed.

4. Check Brake Components

Remove the wheel to access the brake assembly.
Inspect the brake pads for thickness; replace if worn down to 3 mm or less.
Check the brake rotors for warping or scoring; replace if necessary.
Ensure all hardware (caliper bolts, clips) is intact and secure.

5. Inspect ABS Components

Verify that the ABS sensors are clean and properly connected.
Check wiring for any frays or disconnections.
If necessary, replace faulty ABS sensors or wiring.

6. Reassemble and Reset Codes

Reinstall the wheel and lower the vehicle.
Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any error codes from the system.
Perform a test drive to ensure brakes function correctly.
