How do you refill brake fluid on a 2002 ford explorer?

Open the hood. When facing the engine, there is a small oval shaped reservoir with a black round cap on it. It is located on the back wall of the engine compartment to your right. Remove the cap. Make sure to clean the cap off with some type of cleaner or degreaser before you replace the cap. The brake fluid level should be to the edge of the reservoir, BELOW the line of where the cap fits. NOT to the top of the cap. Fill ONLY with DOT-3 brake fluid, found at any local auto parts store.
