Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, brake cleaner, torque wrench, multimeter.
Clear the vehicle of any obstructions and ensure it is parked on a flat surface.
Disconnect the battery to prevent electrical shorts during repair.

2. Address Brake Fluid Issues

Sub-steps:
1. Open the brake master cylinder reservoir cap.
2. Inspect the brake fluid level; if low, top up with the recommended brake fluid (DOT 3 or DOT 4 depending on manufacturer specifications).
3. Check for signs of contamination or moisture in the fluid; if present, consider a complete brake fluid flush.

3. Replace Worn Brake Components

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads for thickness; replace if below 3mm.
3. Check rotors for warping or grooves; replace if damaged.
4. Use brake cleaner to clean the brake components.
5. Reinstall new or refaced rotors and pads, ensuring proper alignment.
6. Torque caliper bolts to manufacturer's specifications.

4. Inspect and Replace ABS Sensors

Sub-steps:
1. Locate the ABS wheel speed sensors on each wheel hub.
2. Disconnect the sensor wiring harness.
3. Use a multimeter to test the resistance of each sensor; replace if readings are outside the specifications.
4. Clean the sensor mounting area of any debris before reinstallation.
5. Reconnect the wiring harness and ensure it is secure.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals.
Use the OBD-II scanner to clear any stored codes.
Perform a test drive to ensure the brake system functions correctly.
