Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.
Disconnect the negative battery terminal to avoid electrical issues.

2. Identify the Source of the Leak

Inspect the Brake Lines:
- Use a flashlight to closely examine all brake lines.
- Look for wet spots, corrosion, or cracks.
Check Brake Components:
- Inspect the brake calipers and wheel cylinders for any visible leaks.
- Check the master cylinder for signs of fluid around the seals.

3. Repairing the Leak

If the Brake Lines are Damaged:
- Use a line wrench to disconnect the affected brake line from the master cylinder and caliper.
- Replace the damaged line with a new one, ensuring it is securely fastened and well routed.
If Calipers or Wheel Cylinders are Leaking:
- Remove the wheel to access the caliper.
- Unbolt the caliper from the mounting bracket and inspect the seals.
- Replace any leaking seals or the entire caliper if necessary.
If the Master Cylinder is Leaking:
- Disconnect brake lines from the master cylinder.
- Remove the master cylinder from the brake booster by unbolting it.
- Replace with a new master cylinder and reattach all lines.

4. Bleed the Brake System

Refill the brake fluid reservoir with the appropriate type of brake fluid (DOT 3 or DOT 4).
Locate the brake bleeder screw on each wheel's caliper.
Use a brake bleeder kit or a helper to pump the brake pedal while you open and close the bleeder screws, starting from the wheel farthest from the master cylinder and working your way closer.
