Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety glasses and gloves for protection.

2. Addressing Brake Fluid Issues

Sub-steps:
1. Open the hood and locate the brake master cylinder.
2. Check the brake fluid level; if low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
3. Inspect for leaks around the master cylinder and brake lines.

3. Replacing Brake Pads and Rotors

Sub-steps:
1. Loosen the lug nuts on the front or rear wheels, then jack up the vehicle and secure it on jack stands.
2. Remove the wheel to access the brake assembly.
3. Remove the caliper bolts using a socket set, then carefully slide the caliper off the rotor.
4. Remove the old brake pads from the caliper bracket.
5. Inspect the rotor; if it's warped or excessively worn, replace it. If not, clean with brake cleaner and reattach.
6. Install new brake pads into the caliper bracket.
7. Compress the caliper piston using a brake caliper tool, then reattach the caliper.
8. Tighten caliper bolts to the manufacturer's specified torque.
9. Reinstall the wheel and torque the lug nuts to the manufacturer's specification.

4. Repairing ABS Components

Sub-steps:
1. If ABS codes are present, locate the wheel speed sensors on each wheel hub.
2. Inspect sensor wiring for damage or corrosion; repair as necessary.
3. If a sensor is faulty, disconnect the wiring harness and remove the sensor from the hub.
4. Install a new wheel speed sensor and reconnect the wiring harness.
5. Clear the error codes using the OBD-II scanner and test the ABS system.
