Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical issues.

2. Locate the Leak

Visually inspect all components of the brake system, including brake lines, calipers, and the master cylinder.
Use a flashlight to identify any wet spots or fluid accumulation.

3. Replace Damaged Components

A. Brake Lines

If a brake line is damaged:
- Use a line wrench to disconnect the damaged section.
- Measure and cut a new brake line to the appropriate length.
- Flare the ends of the new line.
- Install the new brake line using the line wrench, ensuring a tight fit.

B. Master Cylinder

If the master cylinder is leaking:
- Disconnect brake lines from the master cylinder.
- Remove the mounting bolts securing the master cylinder.
- Replace with a new master cylinder and reattach it using the mounting bolts.
- Reconnect the brake lines and torque to manufacturer's specifications.

4. Refill and Bleed Brake System

Refill the brake fluid reservoir with the specified brake fluid type.
Bleed the brake system to remove air:
- Start with the farthest wheel from the master cylinder.
- Use a brake bleeder tool to open the bleeder valve and pump the brake pedal until fluid runs clear of bubbles.

5. Final Checks

Inspect all connections for leaks after repairs.
Reconnect the battery and test the brake system for proper operation.
