Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety goggles and gloves for protection.

2. Identify Leakage Source

Sub-steps:
- Start from the brake fluid reservoir and work your way down the brake lines.
- Clean any visible fluid with a rag to identify the source of the leak more easily.
- Use a flashlight to inspect areas that are typically hard to see.

3. Repair Brake Lines (if necessary)

Sub-steps:
- If a brake line is leaking, cut out the damaged section using a pipe cutter.
- Replace with a new brake line of the same diameter.
- Use brake line fittings to connect the new line securely.
- Ensure all connections are tight and free from leaks.

4. Replace Calipers/Wheel Cylinders (if necessary)

Sub-steps:
- Remove the wheel to access the brake caliper or wheel cylinder.
- Disconnect the brake line from the caliper or cylinder using a wrench.
- Remove the bolts securing the caliper or cylinder and replace with a new unit.
- Reconnect the brake line and bleed the brakes to remove air from the system.

5. Check Master Cylinder (if necessary)

Sub-steps:
- Remove the master cylinder from the brake booster.
- Inspect the seals for wear or damage.
- Replace the master cylinder if leaks are present.
- Reinstall the master cylinder and bleed the brake system.

6. Final Checks

Sub-steps:
- Refill the brake fluid reservoir with new fluid as per manufacturer specifications.
- Bleed the brake system to ensure all air is removed.
- Recheck all components for leaks after the system is refilled.
