Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted with jack stands.
Wear safety goggles and gloves.

2. Inspect and Repair Brake Fluid Leaks

Identify Leak Source:
- Visually inspect brake lines, calipers, and the master cylinder for signs of leaking fluid.
Repair:
- If brake lines are damaged, replace them using the appropriate brake line fittings.
- If the master cylinder is leaking, replace the master cylinder.

3. Bleed the Brake System

Tools Required: Brake bleeder kit or a helper.
Procedure:
- Start with the wheel farthest from the master cylinder (usually the right rear).
- Attach a clear hose to the bleeder valve on the brake caliper.
- Open the bleeder valve and have an assistant press the brake pedal several times, holding it down after the last press.
- Close the bleeder valve and instruct the assistant to release the brake pedal.
- Repeat until no air bubbles appear in the fluid.
- Move to the next wheel and repeat the process (right front, left front, left rear).

4. Inspect Brake Pads and Rotors

Remove Wheel: Use a socket set to remove the lug nuts and take off the wheel.
Inspect: Check the thickness of the brake pads and the condition of the rotors.
Replace: If pads are worn down to the minimum thickness or rotors are damaged, replace them following manufacturer specifications.

5. Test Drive and Recheck

After repairs, take the vehicle for a test drive to ensure proper brake function.
Recheck brake fluid level and inspect for any signs of leaks.
