SMI's™ Vacuum-Assisted Braking System makes towing a vehicle safer and easier with state of the art braking products. When it comes to technological break throughs, SMI leads the pack.
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.
SMI Vacuum-Assisted Braking Systems are more efficient, easier to install, and costs less than other braking systems!
