Solution

1. Preparation

Tools Required: OBD-II scanner, brake fluid, jack and jack stands, socket set, brake pressure gauge, multimeter.
Ensure vehicle is parked on a level surface and the engine is off before starting work.
Safety Warning: Make sure to set the parking brake before lifting the vehicle.

2. Check and Refill Brake Fluid

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" lines.
3. If low, add the appropriate brake fluid type (usually DOT 3 or DOT 4, check owner's manual).
4. Replace the cap securely.

3. Inspect and Replace Brake Components

Sub-steps:
1. Raise the vehicle and remove the wheels to access brake components.
2. Inspect brake pads for thickness; replace if less than 1/4 inch.
3. Check rotors for warping or significant wear; replace if necessary.
4. Inspect calipers for any leaks or damage; replace if defective.
5. Reassemble components and wheels, ensuring proper torque specifications for lug nuts.

4. Address ABS Issues

Sub-steps:
1. If ABS error codes are present, inspect the ABS module and wiring for damage.
2. Repair or replace damaged wiring or faulty ABS components.
3. Clear error codes using the OBD-II scanner and test the brake system.
