i have a 1995 f-150 that has a switch on the front top of the master cylinder that is leaking. i also have the ABS light on in the cab. i went to the part store and they could not identify the switch on top of the master cylinder.
If you are speaking of an electrical switch then it's either the low fluid indicator or the one that indicates air in the lines. When there's air in the lines both the ABS and brake lights will come on. If you're speaking of the little valve connected to one brake line it's the proportioning valve.

go to my pics you will see a picture of that switch with new wiring w/blue tag on it installed by ford garage.by the way that particular re call was known to cause fires in engine compartment. good luck.
At the very least unplug the wire asap. The antilock brakes have different sensors and do not use that sensor, with it leaking that might cause problems with the computer because of the slight fluid and pressure loss the switch is seeing.
