Brakes are a function of the GAWRs. If the truck has 5k front and a 7k rear the truck has 12k of braking performance. Same with a trailer with two 6k axle = 12k lb of braking. The GAWRs on the truck is the truck manufactures rating which doesn't reflect the axle makers max ratings.
NHTSA says this about components of the GAWR:
"Gross Axle Weight Rating is the rated load-carrying capacity of an individual axle and wheel assembly. (It represents the load that may be steadily sustained by the components in the system; i.e., tires, rims, hubs, bearing, axles, brakes, suspension, sub frame, etc. with the GAWR limited by the components with the lowest working rating".
And from;
RMA
• GAWR: Gross Axle Weight Rating (for each axle) -
The maximum weight rating that the components
(tires, rims/wheels, brakes, springs, and axle) of
each axle are designed to support. This is
determined by the lowest design capacity of any
component. In other words, if the wheels have the
lowest design capacity of any component on that
axle, installing tires with a higher load capacity
does not increase the GAWR. By regulation, the
tire load rating times the number of tires on that
axle must equal or exceed the GAWR for that axle.
I doubt the OP is over the DRW trucks 8xxx ?? RAWR/4 tires as its carrying all the load
