SMI's™ Vacuum-Assisted Braking System makes towing a vehicle safer and easier with state of the art braking products. There are many braking systems available today, but as you navigate through our site we are sure you will see the difference SMI makes.
SMI is the only dual-sensing, vacuum-based system. By using the car's own power brakes, pedal pressure is reduced to only 10 pounds in normal stopping. We are also the ONLY Vacuum-Assisted system that maintains the level of vacuum in the system to provide consistent braking from your towed vehicle.
Our Vacuum-Assisted Braking Systems are more efficient, easier to install, and costs less than other braking systems!
