I have a 2011 F-250 four wheel drive. A while back I noticed that once in a while there was some resistance after putting it in drive, sort of like a caliper that didn’t want to release. A little push on the gas pedal releases the tension and everything seems fine. Sometimes it does this, other times it does not. I suspected a sticking caliper and had both on the front replaced since it for sure seemed like the issue was coming from the front. I also had both brake lines replaced on the front. Everything was good for about a day and then it did it again. There is not hot brake smell of any kind and it stops straight. My mechanic is stumped as well. The only other thing to do is to replace both back calipers. Anyone else ever experience this issue? It is a 6.2 gasser.

Miles? Flush the brakes completely. It is possible youe ebrake cable is sticking.

A year or two after launching a buddy's boat in salt water, I had the same issue. In my case it was the back calipers hanging up. I also had a rebuilt caliper (front this time) start sticking after less than a year.

I honestly don’t know about the hill assist. How could I tell if I have it? I have only had the truck about 3 months.

Try to repress the irrational "It's different, so I automatically don't like it," reaction and give it a chance.

Lynn The built in hill assist not the hill descent switch, button or whatever is on the dash.

You may even have hill assist on your truck. my 2012 has it. There is no manual control for it. It is built in and supposedly engineered to hold the vehicle from rolling backward if you stop on a hill and release the foot brake.

Lets not put the OP in another tizzy.

Hill descent is for serious off road conditions at low speed, I have no clue if you are turning it on or if it is defective.

From your owners manual page 278:

Enabling hill descent control and setting the descent speed:

1. Press and release the hill descent button located on the instrument panel. A light in the cluster will illuminate and chime will sound when this feature is activated.

Instead of replacing the calipers, why not inspect the slide pins for corrosion? You can clean & lubricate them to correct a sticky caliper condition. They should easily slide in and out of their bore.

Go one step further.

Use a powered wire wheel and get those slide pine SHINY CLEAN ! Then take a drill bit one size smaller that the slide pin hole and run it up and down the bore. You actually DO want a small amount of play between the pin and the bore. That is why you apply a generous amount of the special disc brake lube.

If the OPs truck was newer, I would suspect something to do with the electric parking brake.

I carry a hand held infrared thermometer with me. Just go around the truck pointing at the calipers/rotors to see if the temps are all within close range of each other. Fool proof method to see if you have one sticking and which one it is as well to see if one is NOT grabbing as it should.

I have had issue with aged flex lines in several trucks causing sticking. No drain back.

I just found out that it does have the hill assist so maybe that is what is going on?? For you guys that have this feature, does it feel like something breaks free when you hit the gas pedal? The previous owner put a level kit on this truck, which I hate, and I'm wondering if dropping the back end a little with the kit causes the hill assist to engage more often than needed.....

I have a 2012 F250 that does the same thing. It is the hill assist thinking you stopped on a hill or maybe you did stop on a slight incline.

Relax, you will get used to it. I don't think you will change a thing by throwing all the stuff at it as suggested by some posts.

Mine has been doing that since new.

A second thought here. If it bothers you you might consider looking in the owners manual and see if it has a fuse. maybe pull it and disable the system, but that may cause a light on the dash. Just a thought.

I also suspect your mechanic needs to bone up a little bit on how that beast works.
