Being as the GVWR/GAWR are heavier/ larger than before, which is what and how the brake capacity is taken from. I think one can assume the brakes should be better per say.
Reality is, to know if they are really better IMHO, you need to compare rigs with like capacities in the gawr/gvwr to know if braking is better. No use comparing 35 series trucks, if you are comparing a 10k, vs a later 11.4k vs some of the current 13k gvwr model. As yes, the newer ones will be better. Lets compare a 99 35 series 10k to a current 25 series 10k model......those might be the same, hopefully better.
