Solution

1. Preparation

Tools Required: Socket set, wrench set, brake fluid, clean rags, pressure test kit (if applicable).
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety goggles and gloves.

2. Identify the Source of the Leak

Sub-steps:
- Visually inspect all brake lines and hoses for cracks, corrosion, or loose fittings.
- Check the master cylinder and brake calipers for signs of fluid leakage.
- Clean any spilled fluid to better observe if new leaks develop.

3. Replace Damaged Components

Sub-steps:
- If a brake line is damaged, use a wrench to disconnect it from the fitting and replace with a new brake line.
- For a leaking caliper, remove the caliper mounting bolts using a socket wrench, detach the caliper, and replace with a new caliper, ensuring to install new brake pads if necessary.
- If the master cylinder is leaking, unbolt it from the brake booster, disconnect the brake lines, and replace it with a new unit.

4. Bleed the Brake System

Sub-steps:
- Fill the brake fluid reservoir with new brake fluid.
- Start from the farthest brake line from the master cylinder (right rear), and using a helper, open the bleed valve while the helper presses the brake pedal.
- Close the bleed valve and repeat until no air bubbles are present.
- Move to the next brake lines in this order: left rear, right front, and finally left front.

5. Final Inspection

Sub-steps:
- Check all connections for tightness and leaks after replacing components.
- Refill the brake fluid reservoir to the appropriate level.
- Test the brake pedal feel before driving.
