Solution

1. Preparation

Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Gather all necessary tools and parts.

2. Identify the Leak Source

Sub-steps:
- Inspect all brake lines and hoses visually.
- Use a clean cloth to wipe any suspected areas to identify fluid seepage.

3. Replace Damaged Components

Sub-steps:
- If a brake line is damaged, use a line wrench to remove the affected section.
- Install a new brake line by flaring the ends if necessary. Ensure connections are tight but do not overtighten.
- For leaking calipers, remove the wheel and caliper mounting bolts, then replace the caliper with a new one.
- If the master cylinder is leaking, remove it from the brake booster by disconnecting the brake lines and the electrical connector, then replace it with a new unit.

4. Refill and Bleed the Brake System

Sub-steps:
- Refill the brake fluid reservoir with the appropriate brake fluid (DOT 3 or DOT 4 as specified).
- Bleed the brake lines starting from the furthest brake from the master cylinder to the closest, ensuring no air bubbles are present.

5. Final Check

Sub-steps:
- Inspect all connections for leaks after the system has been bled.
- Reinstall any components that were removed during the repair.
