Solution

1. Preparation

Gather all necessary tools and parts before starting the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Replace Wheel Speed Sensors (if faulty)

Tools Required: Socket set, torque wrench, dielectric grease.
Sub-steps:
1. Raise the vehicle using jack stands and remove the wheel.
2. Locate the wheel speed sensor on the hub assembly.
3. Disconnect the electrical connector from the sensor.
4. Remove the retaining bolt securing the sensor using a socket.
5. Carefully pull the sensor from the hub; inspect the sensor and mounting area for debris.
6. Install the new sensor, securing it with the bolt and reconnecting the electrical connector.
7. Repeat for all four wheels as necessary.

3. Check and Replace ABS Module (if necessary)

Tools Required: Ratchet and socket set, OBD-II scanner, torque wrench.
Sub-steps:
1. Remove the under-hood cover to access the ABS module.
2. Disconnect the electrical connectors from the ABS module.
3. Remove the mounting bolts securing the ABS module.
4. Install the new ABS module, ensuring proper alignment.
5. Reconnect the electrical connectors and secure all bolts to manufacturer specifications (check torque values).
6. Clear any stored error codes using the OBD-II scanner.

4. Refill Brake Fluid and Bleed the Brakes

Tools Required: Brake fluid, brake bleeder kit.
Sub-steps:
1. Inspect and refill the brake fluid to the recommended level in the master cylinder.
2. Bleed the brake system to remove any air bubbles, starting from the farthest wheel from the master cylinder.
3. Ensure the brake pedal feels firm and responsive after bleeding.
