Car jerks when letting off brake

We are heading on our maiden voyage!

I have a 2012 Toyota Sequioa pulling a 2017 Bullet 247BHSWE. I of course have a brake controller installed, but I'm struggling with getting it properly adjusted. The car is jerking a lot when I let off the breaks. This is particularly annoying in town. If I lower the gain, I can get rid of the jerking, but at that low the trailer breaks don't feel like they're doing much. If I just use the paddle it doesn't slow us down very well. I've tried adjusting the sync, which seemed to help, but only modestly.

Should I expect it to be smooth when releasing the break, or just get used to the jerking?
  • What controller?

    Lots of us started out with timer type controllers and switched to the pricier progressive controllers to eliminate jerking.
  • If this is a new trailer and it has always done it, the axle(s) may be installed backwards. They can be very grabby going backwards.
    It's happened before on the forum.

    What brake controller? If it's time based then no wonder it jerks but a properly adjusted inertia based controller such as a Tekonsha P2 or P3 shouldn't.
