Need info on Upgrading W22 disc brakes

Did a search and could not find anything, so I must be doing something wrong!

Someone on here posted several years ago about up grading the calipers on a Workhorse W22 chassis from 66mm to 73mm calipers. He got 73mm caliper rebuilds and pads from some source in exchange for his 66mm calipers at a very low cost. Said "it stopped like a Ferrare (sic).

Can anyone steer me in the right direction for this info, as I want to do what he did to mine. I have had the WCC brake recall done in 2011. I tow my 24' Pace race car trailer which weight in at 9,400 #s, so I want more braking capability going the down side of mountains!

BTW: it is 2004 so it has the grade braking feature Allison trans.

Any help is appreciated!

Thanks

Dude youre seriously overweight if your trailer weighs close to 10k. Might want to consider a chassis with more GVCW

Has a 22,000 lb. hitch with frame rails extended, professionally installed. Reese equalizer 1,500 lb. bars and two anti-sway controls. Have towed this trailer for 16,000 miles with no issues or bad driving habits! This is not the first time I acceded the GVWR. The trailer has HD 12"X2" 4 wheel brakes. This trailer is a high end quality made trailer with Torsion Flex Dexter axles and is considered a "low profile trailer", as it is only sets 10" from the ground. The trailer has Goodyear radial tires and when I change lanes it and the motorhome handle like a sports car (MH has Michelins). No over steer or under steer! The MH has FDS Konis frt. & rear and a chassis Panard Bar. So as you can tell that I have heavily modified the chassis for the addition GVW. The only issue is I do not feel confident in the brakes on this coach in the mountains because of the additional GVW. I maintain the 2 second rule in distances and drive very conservative in congestive traffic or adverse weather conditions. I read somewhere that someone up graded to 73mm calipers/pads and it made a world of difference!
