UPDATE: Truck is aligned, but the Firestone tech said he couldn't adjust the camber since I didn't install a camber adjustment kit when I swapped out the LCAs! What a bunch of garbage since they've been able to set the alignment with the factory hardware since I bought he truck!

The front brakes are still dragging evenly but not pulling to either side. Still trying to troubleshoot this since I find it very hard to believe that both calipers and flex lines have failed in the exact same way. Now I'm leaning toward the master cylinder based on the even dragging of the calipers.

No, I pulled them all again yesterday to check. What's funny is that they're Motorcraft pads but don't have the tabs/ears on one pad to mark the inside pad. Will check them again in the morning and maybe swap them around to rule that out.

I also ordered new flex lines as a preemptive next step since they're hard to find right now.

Interesting find: I looked up the part number for the pads the dealer gave me (AU2Z-2V001-E) on FordPartsGiant.com and they can't confirm they fit my truck; research shows they fit F150s.. Instead, they list AU2Z-2V001-F or 8L3Z-2V001-C/ 8L3Z-2V001-B as the correct fit for my truck. The pads I have do not have the tabs/ears on them to differentiate inside from outside pads. Going out on a limb and thinking this might be the actual cause of my brake dragging issues. Thoughts?

I wish I knew. I guess you could look them up at Autozone.com or Rock Auto where it shows pictures of the various choices that fit your ride. Compare what you find to what you installed.

I would also check the steel brake lineswhere they go thru the plastic keepers up here rust between them and the line have crimped them but not enough to leak. (salt should only stay on the table )
had to do rad support from salt eat away at frame mount.Son purchased a pickup turned into rust bucket, previous owner use to take it on the beach and into the ocean.

Luckily I don’t have the rust issues (originally a VA truck, now in TN) so the steel lines are clean.

Really want to track this down since this most likely started happening when I changed the brakes in July but only noticed it when I did the suspension refresh.

Just checked oemfordparts.com and the kit I got from the dealer (AU2Z-2V001-D) is listed for F-250s/350s and E250s/350s! Definitely going to get the right pads and see if that fixes the issue!

He's not wrong. They simply never adjusted (or had to adjust) camber on your truck prior to this as it was set at the factory. His statement is accurate.

Ok, thanks for the clarification. Guess I'll break down and get the camber kit at some point after I get the brake issues sorted out. I'm good on camber on the right and "on the border" on the left. Truck is still tracking straight.
