Solution

1. Preparation

Gather necessary tools and replacement parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Wear safety gloves and goggles for protection.

2. Inspect the Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Check the fluid level against the markings on the reservoir.
If low, check for leaks in the system before refilling.

3. Inspect Brake Lines and Fittings

Follow the brake lines from the master cylinder to the wheels.
Use a flashlight to check for any signs of wetness or corrosion on the lines.
Tighten any loose fittings carefully without over-torquing.

4. Inspect Brake Calipers and Wheel Cylinders

Remove the wheel using a socket set.
Inspect the brake calipers for wetness, especially around the piston seals.
Check the wheel cylinders if equipped; look for fluid on the exterior.

5. Inspect the Master Cylinder

Locate the master cylinder, usually near the brake booster.
Check for leaks around the base and at the connection points.
If leaking, replace the master cylinder following the next steps.

6. Replace Damaged Components (if necessary)

For the master cylinder:
- Disconnect the brake lines using a line wrench.
- Unbolt the master cylinder from its mount.
- Install the new master cylinder and reconnect the brake lines.
- Bleed the brake system to remove air.
