2001 Ford Windstar Brake Leak

My ABS light and Brake light came on yesterday. Today I noticed a small puddle of fluid where I parked. What would cause this?

Let Me Guess ... your Cruise Control doesn't work either ??? Check your Brake Pressure Switch .... They are defective on the WS. It's located on the bottom of your Master Cylindar. It screws into the Master Cylindar. Just unplug the old one and unscrew with an adjustable wrench (counter-clockwise of course). Place a small cup under the "switch" to catch the Brake fluid that will come out when the old one is removed. About 1 oz will come out then stop regardless of how full the Brake fluid is. Can buy one on-line for about $22 including Shipping. Dealer S/B around $ 35.
