Solution

1. Preparation

Gather necessary tools: flashlight for visibility.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Locate the Brake Fluid Reservoir

Open the hood of the Mustang.
Find the brake fluid reservoir; it is typically located near the back of the engine bay, near the driver's side.

3. Check Fluid Level

Use a flashlight if necessary to see inside the reservoir clearly.
Observe the fluid level against the markings on the side of the reservoir (minimum and maximum).
If the fluid is below the minimum mark, brake fluid needs to be added.

4. Inspect Fluid Condition

Remove the reservoir cap carefully, checking for any contaminants such as dirt or moisture.
If the fluid appears dark or contaminated, it may require a complete brake fluid flush.

5. Add Brake Fluid (if necessary)

Use only the recommended type of brake fluid (e.g., DOT 3 or DOT 4).
Pour brake fluid into the reservoir until it reaches the maximum mark.
Replace the reservoir cap securely to prevent contamination.
