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 for protection.

2. Identify Leak Source

Inspect Reservoir and Lines:
- Remove the engine cover if necessary.
- Check the brake fluid reservoir for cracks or leaks.
- Examine the brake lines from the master cylinder to the wheels.
Inspect Calipers and Wheel Cylinders:
- Jack up the vehicle and remove the wheels.
- Check brake calipers for wet spots or fluid on the exterior.
- Inspect wheel cylinders for signs of leakage.

3. Repair or Replace Affected Components

If Leak is from Brake Lines:
- Cut out the damaged section of brake line using a tubing cutter.
- Replace it with a new section of brake line, ensuring proper bends.
- Use a flare tool to create new ends and connect with appropriate fittings.
If Leak is from Calipers or Wheel Cylinders:
- Remove the affected caliper or wheel cylinder.
- Replace seals or install a new caliper/cylinder if damaged.
- Ensure proper torque specifications are followed during reinstallation.
If Leak is from Master Cylinder:
- Disconnect the brake lines and electrical connections.
- Unbolt and remove the master cylinder.
- Replace with a new master cylinder and bleed the brake system.

4. Refill and Bleed Brake System

Fill the brake fluid reservoir with the manufacturer-recommended brake fluid.
Bleed the brake system using the appropriate method (gravity, manual, or pressure bleeding) to remove air.
