I wrote an article for Ultimate Hummers Mag in their last edition on big brake upgrades.
There is a good bit of info in that article.
I used AP Racing, 6 piston calipers, two price 14" rotors, etc. I could not go with Brembo because they do not fit an 18" rim--you need to have a 20" rim for the Brembos to fit. Brembo is working with Weld Wheels to get a caliper to fit an 18 inch wheel--who knows if and when that will happen.
The AP brakes give a real firm pedal and also have decreased heat generated after multiple 40MPH to 20MPH stops--origional brakes were about 530 degrees F where the APs are less than 330 degrees F. This means less pedal fade and good brakes for a much longer time when towing or during frequent braking.
My 60 MPH to zero stopping distance did not improve and since I do not tow or make frequent stops, the brake upgrade did not answer the mail. I want to stop faster even with big wheels and tires.
I am working with the AP tech folks now to improve the 60MPH to zero. Pads on big brakes are critical and there are tons out there. I am working with them to find the proper compound to stop faster without sacrificing pad and rotor wear.
The are so many factors in chosing the right brake upgrade, it is important to do a lot of homework first.
I can send you some info on all the factors if you or anyone else sends me a PM--it is too much to post here.
