Where did that information come from on min braking performance on light duty trucks . I have not seen that published .
Jeez..... its just common knowledge around haulers websites.
however.. paste and copy from a NHTSA website several years ago when the question was asked what components are inspected per the GAWRs. NHTSA home page (and other info I copy and paste to note pad) changes every so often and the info they post on that page, beyond a certain time, is lost in cyber space.
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".
Trailer axles are no different per Dexter;
Q&A *The Gross Axle Weight Rating (GAWR) of your running gear is determined by the lowest rated component in the assembly. The capacity of the wheel, tire, axle, brake, springs/rubber and hub are all considered.
JMO but todays large brakes on our LDT size trucks are hands down more effective than the GAWRS as evident of those 30k-36k lb mfg tow ratings vs some years back.
