The ratio of weight to the stopping ability of each brake contributes to the stopping of a towing rig. A trailer with brakes on all axles has enough braking ability to have capacity to spare when fully applied, thus helping the tow vehicle stop in a shorter distance while towing.
The same principle applies to trains; a trio of locomotives is VERY difficult to stop, compared to the same trio with a train of say 30 passenger cars.
My SOB has 2000# axles with (small) brakes only on the front. Applying the controller alone does a respectable job of slowing down the Suburban, even from interstate speed! Of course, they'll fade on you if you use them exclusively like that, but just to show their capacity. Tandem or triple 3500#axles with 11+ inch or disc brakes on all wheels have a lot of stopping capacity, provided they are working correctly.
I was disheartened to read the results about Suburbans, but I can tell you right now that it is better than my Volvo. I bought the Burb right after wagging a 31' Streamline/Volvo combi all over the 101 Freeway
after swerving because somebody cut in front of me and slammed on the brakes
, necessitating an emergency swerve; it was either that, or hit the guy for sure and take it from there
. Now Suburbans aren't good TVs, great! (LOL)
It seems I love the mountains and deserts more than my friends do. I sure miss them!
