Brakes Locking Up!!!

Truck was lifted 3 weeks ago specs in Sig. Everything has been fine but then yesterday I could feel a slight resistance when I let off the gas. Today I started feeling it again and by the time I got to the shop the pedal was all the way to the top and very hard. When I let off the brake the truck wouldn't move without gas and all 4 corners were smoking! Any idea of what could be wrong here?

It's a 2016 with 15k miles and it was all 4!

Yeah all 4 were smoking and the truck was pushing 20psi just to get it to 40mph! Luckily I didn't have to go far once it got to that point. Seemed to start after I hit a pretty good bump yesterday in a construction area. If they cool down it will drive normal again until they heat up again.

They bled the brakes really good and it still does it... Going to have the ABS controller re flashed and see what that says.

They think its the Master... He called the dealer and they said they should be able to warranty it but all 4 calipers are cooked as well.
