Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to prevent vehicle movement.
Disconnect the battery for safety.

2. Identify and Isolate the Leak

Inspect Brake Lines:
- Use a flashlight to examine the brake lines for damage.
- Mark any areas showing signs of wear or leaks.
Check Brake Components:
- Remove the wheel to access the brake caliper and rotor.
- Inspect the caliper and hoses for fluid leaks.

3. Repair or Replace Components

For Leaking Brake Lines:
- If damage is found, cut the damaged section and replace with a new brake line.
- Use a flare tool to create a proper end on the new line.
For Brake Calipers:
- If a caliper is leaking, remove the caliper by unscrewing the mounting bolts.
- Replace the caliper with a new unit and bleed the brake system afterward.
For Master Cylinder:
- If the master cylinder is leaking, remove it by disconnecting the brake lines and unbolting it from the brake booster.
- Replace it with a new master cylinder and reattach the brake lines.

4. Refill and Bleed the Brake System

Refill the brake fluid reservoir with the appropriate brake fluid (DOT 3 or DOT 4).
Using a brake bleeder kit or two-person method, bleed the brake lines to remove air from the system.
Start with the wheel furthest from the master cylinder.
