What is the deal with rear brakes on 2016 F350s?

On my 2009 F350 DRW the brake pads lasted pretty much forever, I checked them multiple times and if I recall I was still on the original pads when I traded in the truck in 2016. On my 2016 F350 DRW it seems the damned pads are made out of used Ritz crackers or something and by 30K they are toast. Even more strange is that the rears seem to wear extra fast and are grinding on the rotors before you know it despite not towing or hauling heavy very often so unloaded the front brakes should be doing most of the work.

What is the current recommendation for pads that actually last a reasonable amount of time? It seems the Ford ones while they seem to perform fine just have terrible service life. Also any tips on replacing the rear rotors as they seem to be chewed up a bit more than I want to let go. Somewhere in my last move I misplaced my service manual DVD which is rather a pain.

Thanks,

Pete C.

I would check the calipers for sticking the rear brakes should last twice as long as the front.

If they're sticking it's something with the abs or master cylinder as both left and right rear wear pretty evenly just way faster than they should.

I replaced pads and rotors on the rear yesterday, all OEM parts, but this time the "Super Duty" pads which claim better wear life. I didn't find anything interesting while changing things, all normal except the diff was a bit low. The front brakes had wear, but not that much, still plenty of depth on the center groove so nothing changed there.

I dug a bit to find when I last did the brakes, unfortunately my maint. log book isn't in as good shape as it was on the previous truck. At any rate I last did the brakes (pads only) in mid November so right at about 6 month and around 10,000 miles ago which is a pretty absurd time and mileage for the any quality brake pads to go from new to backing plate on any vehicle, much less rear brakes on a pickup truck that spends most of it's time unloaded and operates in pretty flat terrain. The truck does see rather a lot of mud, however disk brakes are "self cleaning" and the front brakes are showing no such issues. The front pads are perhaps down 20-25% in that same time frame which would be 40-50k service life which is a lot more reasonable. I will also note that this is not the first occurrence of this, the truck did the same thing in the first 30K since brand new (got new pads and rear rotors at the dealer) and is only at about 65K now on a third set of rear pads and second set of rear rotors.

WTF is wrong with this truck?

I'm getting over 100,000 miles and going strong. On my old truck, it never needed a brake job with 115,000 miles.

Super Duty trucks have extra large rotors and pads. Volvo wagon with 180,000 miles one set of pads, original rotor.

I pump the brakes when stopping and anticipate ahead. Slow down gradually.. Be gentle with your brakes. Don't hit the brakes hard at the last 20 feet before every stop....

The truck I have now has 40,000+ miles.. Brakes look brand new.

When braking hard which you need too sometimes, don't sit on a hot spot. Move forward a few inches.

Don't run through a mud puddle with hot brakes. You can easily warp the rotors. If that happens, you'll get a shimmy when braking.

My 2009 F350 DRW brakes lasted 100K+ with no issues, little wear every time I checked. This 2016 has largely the same brakes, slight change in the caliper slides which I think is better than the old, but that's the only real difference I note. I'm not getting uneven wear between the left and right sides, and within each side the inner pad is just slightly less worn than the outer, good balance overall. I'm also not getting any braking shimmy or warped rotors, the only apparent issue is excessive wear on the rear pads. The fronts seem to be doing ok when they should be wearing a lot faster than the rears. Even there the fronts aren't doing as well as they did on the 2009 truck that was otherwise identical to the 2016. Despite the difference between the 6.4 and 6.7 engines, even the axle weights are the same between the old and new truck as reported by the local truck scale.

The rear brakes are toast again after about six weeks. Truly absurd!

So this past time I did the rear brakes complete with new rotors, checked everything carefully, greased slide pins, replaced a torn pin boot, etc. and all was good. Yes the truck is in the mud regularly with my 1/2 mile mud driveway due to the excessive rain we've had the past few months and the calipers and rotors get packed with mud, but the fronts are in the same mud and are not wearing excessively. The rain may finally be letting up so I can fix my driveway again and not have the mud as a potential issue, but I'm really thinking the problem may be elsewhere. The wear continues to be even between left and right, just excessive so stuck slide pins aren't really a suspect. Only 65k on the truck so the hoses and fluid should all be fine. I'll be replacing the rear pads again this weekend, and hopefully the truck will see less mud so I'll be able to tell how big a factor that is. Thoughts? Anyone else having similar issues?

Something is obviously wrong. I guess that’s a ‘duh’. Back disc brakes are odd. Wonder if the calipers are releasing. When you changed them did the rotors seem ‘free’? With the rear off the ground you may want to start the truck without touching the brake pedal see if the rear wheels are free and truck running. You should have the parking pin play. Then I would hit the pedal and see if they release.

The brakes all around seem to be a bit tight or at least tighter than I'd like, a good solid spin by hand continues perhaps half a revolution. Of course this is the fronts as well and they aren't being eaten.

No, no, no. This is not right, there's something wrong here.

Not the same year of course, but these are 10-year-old calipers, 5-year-old pads and slides. To check the rear you have to pull the drive axle out of the hubs, we used to do that all the time to check free play. But this is what we would look for on every test vehicle unless the design was such that pad to rotor clearance was not designed in, and that was a Ford design spec.

"OE" pads only come in one flavor. If those were Motorcraft designated, they are not "OE" as in installed on the assembly line. They may be sold through the dealer parts system, but not OE. Same with the rotors.

That's what I would expect as well. I'll do more testing tomorrow, fully clean all mud, seat new pads, drive it around on dry ground a bit and then jack up and see if the drag is still excessive. Thanks.
