The 3.5 eco boost available in the Navigator / Expedition comes with varying power outputs, topping out in the Navigator at 450 hp, 510 tq. I’ve been modding trucks for 30+ years, and the premise always adhered to is make sure you increase the stopping power if you’re going to upgrade the HP.
A cursory look at PNs for the brakes on the entry-level Expedition all the way up to the Black Label shows the same PNs for the brakes. Did Ford think that the same brakes would effectively stop 450 hp that stops 300 hp?
Maybe and maybe the brakes are good for the highest HP. And that system was used for the models of lesser HP.
Is there a way to measure that in performance?
I know years ago, the stopping distance was shown on the window stickers. Not sure that data is on the stickers anymore.
Unfortunately, looking at my window sticker, braking information is not available. Looks like it got superseded by the Greenhouse Gas and Smog ratings…
The genesis for my original question was after recently taking possession of my ‘19 Navigator, a front brake job was due in short order because the rotors were warped. Time constraints dictated I just picked up the best rotors I could source locally to knock out the job. I usually conduct copious research when looking for the best brakes for the application, and always upgrading if feasible. After the fact, when conducting a cursory search for brakes, I noticed that all the PNs (primarily Motorcraft) were the same for all lines of the Expedition / Navigator.
Seems like with added performance, upgraded brakes would be warranted. Doesn’t seem to be the case with these trucks. I do drive it like the 6,000# truck this it is, but wasn’t sure if more spirited driving with the OEM spec brakes would end up the same warped result.
Thanks for the feedback Action. Just wanted to make sure I wasn’t missing something.
Long long time ago in a place far away, I worked for the company in the old Parts and Service Division.
At the time I was mostly engaged in the Service end of things with dealership service departments.
I had a situation where brakes and braking material were the subject of a customer situation. The situation was resolved and OE brake pieces were used. The price for OEM friction material was rather eye opening.
At a later point a field engineer had contacted me (by phone) about something. Later in the conversation he asked me about the above situation since he assisted, and I had not gotten back to him. After reporting the outcome, I made an offhanded comment about the price of our brake material. (Since I paid for the repair which was just beyond the warranty period) He latched on to that comment, apparently because he had a go around with someone back in Dearborn. After a minute or so, I kind of stopped listening. The point of his long winded piece was Ford over built most braking systems and friction material was extra over built. Mostly because of a couple of law suits. He also said in the call that his family vehicles (he always drove a Company car) got non-Ford brake friction material because the higher cost was over the top and not worth the added cost. The exception might have been racing, but stock calipers and rotors were not the best for racing.
Now that was a long time ago. And there is nothing so constant as change in the auto industry, so have no idea what is being done now. And some of the difference above was Ford branded, not Motorcraft. But Motorcraft was not immune from the over the top design. Needless to say, while I buy a lot of Motorcraft parts for my fleet. Braking parts are not purchased at a Motorcraft source. And certainly not as a Ford part either. Although nearly all of my rides are too old to be serviced with certain Motorcraft parts.
I know my Navi had ceramic brake pads when I bought it. So that is what I used when it came time to replace.
No sounds and stops well. Plus I tow a 7400 pound boat and trailer from time to time.
The trailer has drum brakes on all 4 wheels and I know it is back there. Just don't have any issues with towing or stopping.
And I am very easy on all of my rides. Never really drive aggressively.
I think the same is true for F 150 Truck. All of the brakes are the same. (This is a guess) Step into a F 250 and those are larger brakes.
Mine boat is an older Wellcraft 2600 SE. With trailer I think it is about 30 feet. Maybe a lil more.
8 1/2 wide the limit on the road without a permit. And a single 5.7l MerCruiser.
In many (perhaps, most) cases, what people think is "warped rotors" are not really warped rotors, but just brake pad material transfer onto the rotor, leading to vibration when braking (note that you usually don't see it on the rotor). Keeping brakes engaged with a substantial effort while the car is not moving, but rotors are very hot will do that quickly. Different pad materials are prone to that to a different degree.
My gen 4 expy was warping the factory brakes. They use cheap metals on the OEM. Put powerstop slotted and drilled brake kit on and the truck with load brakes like a race car and no more warping.
