Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure the vehicle with wheel chocks.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Locate the Leak

Sub-steps:
- Use a flashlight to identify the source of the leak by inspecting brake lines, hoses, calipers, and master cylinder.
- Clean the area around potential leaks to help identify the exact source.

3. Replace Damaged Components

Sub-steps:
- If brake lines or hoses are damaged, use a line cutter to remove the affected section and replace it with new brake line or hose, ensuring proper fitting.
- For calipers, remove the caliper mounting bolts with a socket set, detach the caliper, and replace any leaking seals or the entire caliper if necessary.
- If the master cylinder is leaking, unbolt it from the brake booster and replace it with a new master cylinder.

4. Refill Brake Fluid

Sub-steps:
- Once repairs are made, refill the brake fluid reservoir with the appropriate type of brake fluid (DOT 3 or DOT 4 as specified).
- Bleed the brake system to remove any air bubbles from the lines. Start from the furthest wheel and work to the closest.

5. Test Component Functionality

Sub-steps:
- Reconnect the negative battery terminal.
- Start the vehicle, check the brake pedal feel, and ensure no further leaks are visible.
