Solution

1. Preparation

Gather necessary tools and parts for repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Replace Brake Pads and Rotors (if worn)

Tools Required:
- Jack and jack stands
- Lug wrench
- Socket set
- Torque wrench
- Brake cleaner
- C-clamp
Sub-steps:
1. Loosen the lug nuts on the wheel, then jack up the car and secure it with jack stands.
2. Remove the wheel to access the brake assembly.
3. Remove the caliper bolts and slide the caliper off the rotor. Use a C-clamp to compress the caliper piston if necessary.
4. Remove the old brake pads and inspect the rotor for scoring or warping; replace if necessary.
5. Install new brake pads and reassemble the caliper, tightening bolts to the manufacturer’s specified torque value (typically 20-30 ft-lbs).
6. Reinstall the wheel, hand-tighten the lug nuts, and lower the vehicle to the ground. Torque the lug nuts to the specified value (typically 80-100 ft-lbs).

3. Inspect and Replace ABS Sensor (if faulty)

Tools Required:
- Multimeter
- Socket set
Sub-steps:
1. Locate the ABS sensor on the wheel hub and disconnect the electrical connector.
2. Use a multimeter to test the sensor for continuity; replace if it does not meet specifications.
3. Remove the sensor from the hub using a socket set and install the new sensor.
4. Reconnect the electrical connector securely.

4. Refill Brake Fluid (if low)

Tools Required:
- Brake fluid (DOT 3 or DOT 4 as specified)
- Funnel
Sub-steps:
1. Open the brake fluid reservoir cap located under the hood.
2. Inspect fluid level; if low, add new brake fluid using a funnel until it reaches the recommended level.
3. Replace the reservoir cap securely.
