Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a level surface and securely lifted with jack stands.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Brake Fluid

Tools Required: Brake fluid, funnel, brake system bleeder kit.
Inspect the brake fluid for contamination and ensure it is at the correct level.
If contaminated, use a funnel to remove old brake fluid from the master cylinder and replace with manufacturer-recommended fluid.

3. Inspect and Replace Brake Pads and Rotors

Tools Required: Socket set, torque wrench, brake cleaner, new brake pads, new rotors (if needed).
Remove the wheel to access the brake assembly.
Remove caliper bolts and lift the caliper away from the rotor.
Inspect brake pads for wear; replace if thickness is below 3mm.
If rotors are warped or below minimum thickness, remove the rotor and replace it with a new one.
Reinstall caliper, ensuring proper torque on bolts.

4. Check and Replace Brake Lines

Tools Required: Brake line wrench, replacement brake line if needed.
Inspect brake lines for any signs of wear, corrosion, or leaks.
If damage is found, use a brake line wrench to disconnect the damaged line and replace it with a new one. Ensure all connections are tight to prevent leaks.

5. Test ABS Module and Sensors

Tools Required: OBD-II scanner, multimeter.
Reconnect the negative battery terminal and use the OBD-II scanner to clear any existing codes.
Drive the vehicle to check if the ABS warning light reappears; if it does, use the multimeter to test the ABS sensors for proper voltage and continuity.
