Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Ensure that the vehicle is stable before working underneath.

3. Inspect and Identify Leak Source

Sub-steps:
- Check the brake fluid reservoir cap for secure fit.
- Inspect brake lines starting from the master cylinder to the wheels.
- Look for any wet spots, corrosion, or physical damage on the lines.
- Inspect the brake calipers and wheel cylinders for any signs of fluid leakage.

4. Repair the Leak

Sub-steps:
- If a brake line is leaking, replace the damaged section and ensure proper routing and secure fittings.
- If the caliper is leaking, replace the caliper with a new or remanufactured unit.
- For a leaking master cylinder, remove it from the vehicle, replace it with a new unit, and ensure proper bleeding of the brake system afterward.

5. Refill Brake Fluid

Sub-steps:
- Use the appropriate type of brake fluid (DOT 3 or DOT 4, depending on specifications).
- Fill the reservoir to the recommended level and ensure the cap is secured.

6. Test the Brake System

Sub-steps:
- Press the brake pedal several times to ensure it feels firm.
- Check for any signs of leaks after pressurizing the system.
- Lower the vehicle and conduct a road test to ensure proper brake function.
