Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Engage the parking brake for safety.

2. Retrieve and Clear Error Codes

Use the OBD-II scanner to retrieve any brake-related error codes.
Document the codes for reference.
Clear the codes and check if they return after a test drive.

3. Inspect and Replace Brake Components

Brake Pads and Rotors:
- Remove the wheel using a socket set.
- Inspect the brake pads for thickness; replace if below the manufacturer’s specifications.
- Check rotors for warping or scoring; replace if necessary.
Brake Fluid:
- If the fluid is low or contaminated, drain and replace with manufacturer-recommended brake fluid.
- Use a brake bleeder kit to remove air from the system after refilling.

4. Test and Replace Brake Switch

If the brake switch is faulty, disconnect the battery, remove the switch, and replace it with a new one.
Reconnect the battery and test the new switch for proper function.

5. Inspect and Repair ABS System

Check the wiring harness and connectors for the ABS module and wheel speed sensors for any signs of damage.
If necessary, replace faulty sensors or repair wiring as needed.
