Car jerks when letting off brake

Reese Brakeman can be several different including timed and digital.

There are currently 2 Reese Brakeman Controllers and both are timed, not inertia ... unquestionably this is the OP's issue. Remove it and invest in a Tekonsha P2 or P3 and your problem will be solved, assuming the brakes themselves are properly adjusted, which they should be on a trailer this new. If after installing a P2 or P3 you find the brakes are still grabbing at low speeds they may need to be adjusted OR as I did you may have to have a dealer tech chamfer the leading edges of each brake shoe - that will absolutely eliminate any grabbing.

I think you are going to the most difficult solution before trying the simpler more obvious solution. Just adjust the brake controller itself.

If you bothered to read what I actually wrote you would (or should) realize I did not "go to the most difficult solution before trying the simpler more obvious solution" but rather did suggest multiple steps that could be taken to resolve this issue, starting with the simplest - replace the time based controller with an inertia based. :S

As far as chamfering the brake shoes is concerned, this is a technique used by many techs that will absolutely correct chattering or grabbing when the brakes are applied when no other solution will. It's also the solution I used on my own trailer to solve this exact problem the OP is complaining about.
