Replacing brake pressure switch--please help!!
I need to replace the brake pressure switch (otherwise called the "deactivation switch") in my 1995 Ford Windstar. OK--a Windstar isn't a truck, I know. ;>)
But this is the closest forum I could find for help!
Anyhow, my cruise control quit working. So I've done some diagnostic testing on my own and traced the problem to the brake pressure switch. It's fairly easy to access--at the front lower area of the brake master cylinder.
My question is, can the switch be replaced with minimal loss of brake fluid, as long as I have the new replacement switch ready and immediately install it after I unscrew the bad switch? Or do I need to be concerned with brake fluid loss, bleeding the brake system, etc.
I bought a can of electrical contact cleaner because the switch connector is all oily, as is the connector to the speed control servo. I heard that this is quite common when the brake pressure switch leaks or goes bad, so I'm going to clean all of the connections when I replace the switch.
Thanks for any help and/or suggestions on replacing the switch.

Never having replaced the switch you're talking about, I don't know for sure if you need to bleed the system after replacing it. I would bet, though, that you can find the answer in a Chilton's or Haynes manual.

Not in Haynes manual...
I have a Haynes manual, but it doesn't specifically mention the procedure for replacing the brake pressure switch.
Perhaps I can find a service garage and ask a mechanic about it.
