I had to replace my F150 Pads at 23k. The ones I put on have lasted a lot longer though..

i would guess pads, mine squeaked here and there for about a month. not consistant at all and not that often either. then once day it was a horrid metal on metal contact. i was sure the pad must have fallen apart as the outside pad i could see had a lot of material left. my front left rotor was toast before i was able to get home, but it had a lot of miles on it anyway. turns out all the my pads were gone, but the outsides still looked like they would have had plenty of life left. looking back they did have 60k miles on them.

That's a pretty bad casting, Dude! What'd you pay for that rotor, maybe twenty bucks?

I've had cheap rotors last a week. They warp and gall. Chunks rip out of them, like in your photos. Metallic pads are often harder than the Chinese pot metal used in the twenty dollar rotors and they end up looking like yours. A healthy rotor should look polished and shiny. Looks like you have some garbage parts there. I've seen plenty of those before I wisened up and started paying for the good stuff.

Jack up the wheels and spin them to see what's going on. Pull a tire and take a look. If it's making noise you could have a caliper sticking or a bad pad. When you change the pads, check the hardware. Change the caliper pins if the are worn, use any clips that are supposed to be there and make sure everything moves well.

And next time buy better quality parts, they will certainly serve you better - unless you enjoy rolling around on the ground changing this crap.

Well I would expect these parts to be top notch considering they are original OEM.

Had tires rotated today and had a chance to spin the wheels off the ground. No noise. Seems to only be noticeable when braking which leads me to think the rotors/pads. Gonna upgrade to some slotted drilled while they r off

Wow, that's OEM stuff? I suppose Ford is using a metallic pad, and I've seen metallic pads treat rotors that way. I prefer to use ceramic ones for that reason, though I'm told the stopping distance is better with the metallic.

Of course check the pads, as one caliper may not be sliding and one of the pads is worn way down. Make certain the calipers can slide on their pins; one may be frozen. But I've also seen brakes behave that way that still have life in them. That's some aggressive wear on those rotors and combined with pads that have become grooved or worn, they can make noise.

I've had combinations that lasted less than 30,000 miles on my 2000.

Be careful with the slotted/drilled rotors; some use pretty cheap castings. I had great luck with DBA rotors on my Excursion. They were the only ones that didn't warp in a week, though I don't know if they make a rotor for the Expedition.

Thanks for the help! I’ll see what they look like early next week

I am selling my factory brakes from my 2017 that only had about 600 miles on them. I upgraded to EBC rotors and Yellow stuff pads.
