Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Wear safety gloves and goggles.

2. Inspect Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Remove the cap and check fluid levels; refill if necessary.
Clean any residue around the reservoir to identify future leaks.

3. Examine Brake Lines and Hoses

Follow the brake lines from the master cylinder to each wheel.
Look for any signs of wear, cracks, or leaks.
If leaks are found, prepare to replace damaged sections of the brake line.

4. Check Brake Calipers and Wheel Cylinders

Remove the wheel to access the brake calipers and wheel cylinders.
Inspect these components for wetness or fluid accumulation.
Replace any leaking calipers or wheel cylinders as needed.

5. Inspect Master Cylinder

Check the master cylinder for leaks around the seals.
If leaking, remove the master cylinder by disconnecting the brake lines (use a line wrench to prevent damage).
Replace the master cylinder with a new one, ensuring proper torque on connections.
