Solution

1. Preparation

Gather necessary tools: a clean rag, funnel, and brake fluid as needed.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Access the Brake Fluid Reservoir

Open the hood of the F-150 by pulling the hood release lever inside the cabin.
Secure the hood with the prop rod to prevent it from closing unexpectedly.

3. Inspect Fluid Level

Locate the brake fluid reservoir near the driver's side.
Clean the area around the reservoir cap with a rag to prevent dirt from entering when the cap is removed.
Remove the cap by twisting counterclockwise, taking care not to let dirt enter the reservoir.

4. Check and Top Off Fluid Level

Visually inspect the brake fluid level against the "MIN" and "MAX" markings on the reservoir.
If the level is below the "MIN" line, use a funnel to add the appropriate brake fluid type until it reaches the "MAX" line.
Replace the cap securely by twisting it clockwise.

5. Final Inspection

Wipe any spilled fluid with a clean rag.
Check for leaks around the reservoir and brake lines after topping off.
