Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and securely lift it using jack stands.
Wear safety goggles and gloves.

2. Inspect and Repair Leaks

Sub-steps:
- Visually inspect brake lines, hoses, and connections for leaks.
- If a leak is found, replace the damaged brake line or hose.
- Tighten any loose connections to ensure there are no leaks.

3. Replace Brake Fluid

Sub-steps:
- Use a brake fluid siphon to remove old fluid from the master cylinder reservoir.
- Refill the reservoir with the recommended brake fluid (usually DOT 3 or DOT 4).
- Ensure the cap is securely fastened after refilling.

4. Bleed the Brake System

Sub-steps:
- Starting with the wheel farthest from the master cylinder, loosen the bleeder screw on the brake caliper (usually requires a wrench).
- Have an assistant press the brake pedal several times and hold it down.
- Open the bleeder screw to allow fluid and air to escape, then close it before the pedal is released.
- Repeat for each wheel, moving from farthest to closest (right rear, left rear, right front, left front).
- Check the master cylinder fluid level frequently and top off as needed.

5. Test the Brake System

Sub-steps:
- After bleeding, press the brake pedal to ensure it feels firm.
- Test drive the vehicle in a safe area to confirm proper brake function.
