you can see it on the right side the orange piece I need to know what this is if someone could tell me or send me links pleease and thank you
If you are talking about the part in the top of the master cylinder consider yourself very fortunate. The brake switch has caused many fires and has even destroyed a home or so where a Bronco or F-150 was garage parked. Evidently power goes through this switch even with the ignition switch off. Switch fails, ignites brake fluid and bad things have happened.
Ford issued a safety recall to replace it free but yours may have missed it.
It is time to take it to a Ford dealer.
If your ignition control module is a black Motorcraft (CCD system) do not replace it with a gray one (Push Start system). The wiring harness is different.
FTE is great! Be a supporter to keep this forum going. 94 5.8 EB, towing package, K & N drop in, MSD Blaster, 9 mm Ford Racing Wires, mechanical oil and temp guages and the rest all stock.
In hindsight, if someone was pressing gently on the pedal, enough to close the MC's compensation ports and lightly pressurize the brake system, the old switch maybe could be unscrewed and new one screwed in without getting air in, as fluid flow would be always coming out the top.
Once you get your brakes bled, PLEASE take it to a Ford Dealer and have them do the recall action!
They would look at the switch, if it was leaking out of its internal seal, they would replace it (you did that already, so should be OK there). Then they unplug the wiring harness from the switch, plug the harness into a safety harness, and then plug the safety harness into the switch. The safety harness is two wires, one (the 12 volt hot lead), has a 2 Amp fuse in an inline fuse holder wrapped in it. The idea is that if the switch diaphragm goes bad again and brake fluid comes through, the resultant current draw due to the leakage circuit will pop the 2 Amp fuse, before a fire starts.
They would want to mark your truck's serial number off of the recall list, so they probably won't just give you the fused safety harness over the counter, they probably want to install it themselves to meet the recall liability requirements. It's all no charge anyway.

The VIN number can tell you, you may have to call the ford dealer though. I had found old posts from when the recall was released (back in 05' or 06') and some people compared the old vs. new like I did. I also saw an article somewhere on the web where they described the original brake pressure switch being red/orange, so I realized mine was original. When I went to the ford dealer they said the recall hasn't been taken care of on my truck.
