The BrakeSmart controller is made by Master Brake Systems in Dallas (
www.masterbrake.com).
While everyone else in the trailer world is cowering in a corner passing off '50's technology, Master has had the courage and good sense to go forward and design and produce equipment that is sorely needed in today's heavy towing world (and I believe will be legally required at some time in the future).
The first product in this line was the Elecdraulic actuator (electric over hydraulic) that came out a few years ago with far more electronics than seemed necessary to run a screw-jack in proportion to the brake signal from the controller. I have used them since they were new (usually at 36k gross with a tridem on Kodiak discs behind my F-450 4x4 tractor), and I can tell you that the actuator is top drawer equipment (the Kodiak disc calipers... . another story).
I have waited for the BrakeSmart for a couple of years as the guys at Master have told me about its development. What it does is put a little pressure transducer (pizeo I believe) with next to no swept volume (swelling of a brake hose or line under pressure will be much more volume) to read the brake pressure you are trying to get on the tractor. An inertial unit has to pause while the pendulum takes a WAG on what you MIGHT have wanted for braking, if only the trailer brakes were in the game yet. A mechanical unit can make a more informed guess, but it is ultimately dependant upon adjusting for pedal position and can hardly be adjusted in a hurry. The BrakeSmart looks at the line, and immediately tells the brakes to apply to the level set on the controller proportional to the measured effort.
IF you have the matching Elecdraulic actuator, there is a matching transducer in the brake circuit of the trailer, so the brake proportioning adjustment on the controller merely has to give an output the calculates the ratio between the truck and trailer that you set in a fast push of the key(s). All with NO detectible delay!!!!! It is as close to driving an empty car that trailer brakes will ever get!
What else can it do? Well, to begin with, it will operate regular electric brakes, take a look at the number of axles, display the results to you, and give you an output to match the number of axles on the trailer. Got air suspension? The BrakeSmart will lower it for you to unload, and lock the brakes (if you have Master actuator) while you are at it. Got air jacks? It will run them too. Of course, it will communicate with any Master devices on the line back there and display error messages on the screen if something is wrong. It will even tell you what it is hooked to when you first plug in.
The truck ABS does not bother the controller, BUT, the actuator is designed for ABS in the trailer as soon as testing has been concluded. You can buy discs with tone rings now, and plug the ABS unit into one of the plugs on the acutator that seemed so surplus a few years back.
I do not work for Master, or sell anything for them. I operate a service business that tows all over North America, sometimes in a big panic and LOTS of it in the Rockies. This stuff is what I needed to downsize equipment out of class 8 air brake rigs and into medium trucks. I now have braking in these units far superior to what I have in our regular tractor-trailer units. I have used the BrakeSmart personally (along with Elecdraulic) for most of this year, and, guys, THIS is the future.
