Parking Brake Service NOW!!!

Happened to me too. Dealer replaced a bunch of rear break parts, now it's fine. I can tell you tomorrow what parts they were.

That would really be helpful, thanks.

The interesting thing is that the warning goes away when you pull the E brake after you put it in park.

mine doesn’t. I engaged/disengaged it never shut up. Even getting out and letting it sit, as soon as I opened the door without even getting in the truck, it was going off.

supposedly the actuators tested fine. Thats why they are talking directly to Ford.

Just heard from the dealer finally. Turns out it was an actuator. Or rather the caliper. Caliper was leaking brake fluid into the actuator. They have an actuator in stock but a caliper wont be in until Monday or Tuesday.

Learned something, too. The actuators are on all 4 corners, and it was the right-front that failed on mine. When I got under the truck to see things myself, i only looked at the rear axle. Not that i would have necessarily seen anything. But I’m old i guess and only expected to see EBrakes on the rear.

On the Raptor with an electric transmission, the parking brake automatically disengages but does not automatically engage, which I find a shame.

Not sure this is true. Mine auto engaged (24MY) when I parked on a sand dune to take pictures. It was facing down the hill at a pretty decent degree and I actually fumbled for a second when it didn't go anywhere when I was in drive.

Yes indeed it engages automatically when the truck is on a slope (which is what the instructions say).
But on flat ground when I turn off the ignition I can feel the truck moving slightly and "landing" on the transmission.
It would be good if the handbrake could engage each time (possibly with a switch on the APIM to activate it or not).

Just engage the parking brake when you want it engaged. The lever is right on the console.

There's no need for any more automatic features. That's just more to go wrong.

Got my truck back this morning. It was actually ready yesterday but, as i told the guy when he called just after 5pm, I’d already been fighting traffic for an hour and was on the other side of town. LOL.

anyway, slight correction. It was left rear, not right front. Guess the service writer got mixed up. Still gonna get under there later and look at some things.

Here’s the invoice:

good to know!! So all 4 corners have an actuator and the park brake button will apply grip to all 4 corners. Do the actuators use the regular brake pad and disk rotor? (same parts coming together just different system to engage, hydro brake lines vs electric actuator?) Or does park brake use different friction pieces to hold the car? Do the actuator bolt onto the caliper or are they built internally into it? thanks for share your knowledge!

Ah, I noticed that truck seems to drift 4-5" when I park on nearly level ground. More travel than our previous cars. And like you say, it seems to jolt a little harsher than I would like and I assume it land on tranny pawl or gears. Apparently park brake tries to be smart and engage if slope is large enough. hmm, so what is the advantage of not engaging on flat ground? wear and tear? Dunno why they not apply all the time, less complexity.

I'm afraid that by constantly resting on the gearbox, it will damage it in the long term.
Ford has given us a gear lever that goes into P by itself (useless gadget), why not have the automatic handbrake ALL the time, like other manufacturers...

Not all US Rangers have the automatic shift that goes into park. It's just SOME Lariats and Raptors.
Our automatic transmissions have a pawl that locks the trans when in park. We (unfortunately) can't get a manual gear box.
