thanks .... my son tried to convince me to look for a surly with disk brakes .... he is of the opinion that disk brakes are the way to go, but I wanted a long haul trucker.
I will see how the brakes work, and if they need better brakes, I will sort it. I might first try Kool stop salmon brake blocks and see if there is an improvement
I had the tekro stock brakes and it worked fine for my 180-300 pound loads. That being said the disc trucker is nice and has appeal, but it is overkill for most. I will wait until there are more hydraulic road options with thru axles.
