Brake Pressure Switch Problem!

My 6.4 hasn’t had cruise since I bought it and today I decided I’d fix that. I got a new brake pressure switch (under the master cylinder) and started. Thankfully it went horribly and the wires in the plug were so brittle they broke upon unplugging it.

I’m now left with this



I’m at a loss for what the hell to do at this point since there about 0 room to work down in there and there’s not enough wire to simply put er back together.

advice would be greatly appreciated!

I understand your dilemna completely. My switch went on vaca so I decided to replace it. Easy job right?

Got the old one out simple enough. Went to spin in the new one and couldn't catch a thread. Decided the only way to do it was to pull the Master cylinder and do it on a bench.

I suggest you do the same. That will give you a flawless repair and it will open up the work area enough to properly repair the plug. Pulling the MC is not hard. Trying to thread the sensor with zero room and tearing the skin off your hand trying is much worse. After you do the plug and the sensor, don't forget to bleed your brakes.

Good luck,

Denny (you'll welcome your cruise back)

Well after a few beers I was less pissed and got back at it. Ended up un-pinning the connector and soldering a length of wire onto the pins to give a bit of wire to play with. Undid the harness the broken off wires were in and snaked em into the fender well to solder to the new wires.

Kind of a redneck fix but it works! Glad to have cruise back

Hey DD, if you disconnect the master cylinder won't you then have to bleed the brake system?

Yes Vern. (I stated that)

Not a big deal.

DD, Sorry! Guess I should have read it all the way through. I'm experiencing intermittent issues with my CC sometimes it works sometimes it doesn't on my 2008 F350 Dually, think I should bite the bullet and replace it or wait? Did you all have issues for a while or did it cut out all at once? I read that the replacement switch is part # SW 6350, can you verify?

Thanks

My truck was intermittent until it just gave up. Generally it is the switch.

Can't remember the ford part number, but use motorcraft only is my recommendation.

SW 6350 is the correct number. Ebay has it right now for 30 ish with a fresh pigtail.

Have fun!
