Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, brake fluid tester, jack and jack stands, torque wrench.
Safety Warnings: Always engage the parking brake and ensure the vehicle is on a flat surface before lifting. Wear safety goggles and gloves.

2. Address Brake Fluid Issues

Check Brake Fluid: If low, fill it with the recommended DOT fluid (check owner's manual for specification).
Bleed Brake Lines: If air is suspected, bleed the brake lines starting from the wheel farthest from the master cylinder (usually the right rear).
Inspect Master Cylinder: If fluid is contaminated, replace the master cylinder.

3. Replace Worn Components

Remove Wheel: Use a jack to lift the vehicle and remove the wheel to access brake components.
Remove Brake Caliper: Unbolt the caliper and hang it using a wire to avoid stress on the brake line.
Replace Brake Pads: Remove old pads and install new ones, ensuring they are properly seated.
Inspect and Replace Rotors: If rotors are worn or damaged, remove them and replace with new ones. Torque the new rotors to manufacturer specifications.

4. Check and Repair Brake Lines

Inspect Brake Lines: Look for any signs of wear or leaks.
Replace Damaged Lines: If damage is found, replace the sections of brake line using appropriate fittings and ensure all connections are tight.
Bleed System Again: After replacing lines, bleed the system to remove air.

5. Test the ABS System

Activate ABS System: Using the OBD-II scanner, perform an ABS test to ensure all sensors are functioning.
Check Wheel Speed Sensors: Inspect and clean wheel speed sensors; replace if faulty.
