That's internet urban legend stuff.
I have read literature from both Ram and Ford that describe how when combined weight rating rises, so must the trucks service brakes because it's part of the overall braking performance of the entire load.
Scott, you do realize that GCWR is based on rear gear and HP/Torque not brake size.
Don't know about the 2004, but the rear brake shoes for a 2001 Ram 2500 is the same as the 3500 DRW.
I'm sorry but according to Dodge/Ram, that is not the only factor in how they calculate it. They do indeed factor in braking and also, cooling and frame build, which had to be updated before they could rate them at 30K. I know that between very similar models, like some 3/4 & 1T are the same but that's just because the parts span a range of ratings and then there's standardized parts as well.
Don't get me wrong, I'm not saying they have different brake shoes for every little weight change, the brakes clearly span a range of capacities.
The bottom line is these manufacturers say the trucks brakes are there to be part of the overall combination braking force.
