Solution

1. Preparation

Tools Needed: Wrench set, brake fluid, clean rags, safety goggles, and gloves.
Safety Warning: Ensure the vehicle is on a level surface and secure it with wheel chocks. Wear gloves and goggles to protect from brake fluid, which can damage paint and irritate skin.

2. Inspect Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Check the fluid level against the minimum and maximum markings on the reservoir.
If low, add the appropriate brake fluid specified in the owner's manual.

3. Examine Brake Lines and Hoses

Starting from the master cylinder, trace the brake lines to each wheel.
Use a wrench to tighten any loose fittings.
Replace any lines that show signs of wear or leaks.

4. Inspect Brake Calipers and Wheel Cylinders

Remove the wheel to gain access to the brake components.
Inspect the calipers and wheel cylinders for wetness or fluid buildup.
Replace any leaking caliper seals or wheel cylinders as necessary.

5. Check Master Cylinder

Inspect the master cylinder for any signs of leakage at the seams or around the connections.
If a leak is present, replace the master cylinder.
