I have purchased 2 of these LG-15...to replace the JP Unit on my Mini T-1 and T-1, as well, I’m removing those magnets....

My brakes are almost like yours...worse on the T-1 then the mini....not proportional grab like crazy, when relax and re-apply they grab again. So removing these magnets and putting this controller, I hope all will be perfect.

I have another jet also with JP brake and they don’t grab at all....I need to take them apart to see the difference.
