My 2500HD started shuddering when under very heavy loads. Not sure if this is correct but, per some break info I found online, I think on PowerStop web page, they say that if you get the rotors very hot, such as down a very steep grade, and then stop the vehicle and hold the brakes applied after stopping, some of the metal from the pads bonds with metal of the rotor. Over time, this causes "hot spots" causing the pads to grab more in some spots on the rotor.

When the pad grabs on one side and then grabs at a slightly different time on the other side as the wheels rotate you get shudder.

When I had to keep my brakes on for extended braking, the shudder got worse. Depending on how hard I pressed the peddle, it would almost jerk the steering wheel out of my hands. Bad feeling when your rig doesn't want to stop. Let brakes cool and it would stop ok but I could still feel a slight shudder.

I replaced all 4 with a set of heavy duty vented rotors and pads, followed their break in procedure, and I try not to hold the brakes on after stopping. All has been good since.

Not sure if this issue could affect a trailer brake.

Try cleaning all of your braking surfaces with a solvent made for brakes.
