This is a very easy thing to check. Under the hood on the left side (drivers side) near the rear of the engine bay. You will see, a small rectangle box (fluid reservoir) attached to a circle (master cylinder). Make sure the truck is turned off. On the fluid reservoir, lift the cover off. It should attach on four places, like small tabs. In side you will see a rubber boot that should stay with the cover. The fluid has two small 'holds', forward and rear respectively. There are fill level lines on the side of the reservoir. Fill them up to the line, don't over fill. Place the cover with the boot back on, ensuring it seats fully.
