Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Inspect and Identify Leak Source

Open the hood and locate the brake fluid reservoir.
Check fluid level; if low, refill with manufacturer-recommended brake fluid.
Inspect brake lines visually for any visible leaks or damage.
If leaks are found, use a clean cloth to wipe the area and confirm the leak source.

3. Repair or Replace Damaged Components

For Brake Lines:
- Use a wrench to disconnect the affected brake line.
- Replace with a new brake line and secure with proper fittings.
- Torque specifications for fittings should be followed as per manufacturer guidelines.
For Brake Calipers or Wheel Cylinders:
- Use a socket set to remove the caliper or wheel cylinder.
- Replace seals or the entire assembly as needed.
- Reinstall and torque to manufacturer specifications.
For Master Cylinder:
- Disconnect the brake lines and electrical connectors.
- Remove the mounting bolts using a socket set.
- Replace the master cylinder if leaking and reinstall using new seals.

4. Bleed the Brake System

Use a brake bleeder kit to remove air from the brake lines.
Start with the wheel furthest from the master cylinder and work towards the closest.
Ensure all connections are tight and check for leaks post-bleeding.

5. Final Checks

Refill the brake fluid reservoir to the recommended level.
Inspect the system for any remaining leaks.
Test the brake pedal feel before driving.
