Good to know. I'll do a better flush of the entire system when I have time. I got stainless braided hoses for the front, where you referring to something different than that?
Also I want to say thank you for taking the time to address all the information in this thread with real data.
GA9130 HH is on the pads and the more I have driven it the better it has gotten. I only drive the truck a couple days a week. It was definitely a worthwhile upgrade. Not that the OEM brakes for 2014 were terrible, but this feels like a nice improvement. I look forward to finding out how it does pulling my 25' - 4 place PWC trailer this summer. It's got surge brakes on it, but I think this will be an improvement.
