Dethmers Manufacturing Company Smi Delta Force. The benefit to the driver is that the coach sends braking contours to the actuator at highway speeds. This allows the brake controller to respond quickly to changing road conditions. The Smi system utilizes proportional technology which gives you the same brake feel at any speed. The controller is designed to be installed on a flex ball pivoting actuator just like our Dethmers brake controllers. This allows for easy installation and removal. One simple process activates the wireless capability. No wires or connectors required. Because the wireless communication system is based on the vehicles electrical system a single mounting bracket is used to support the brake control system and braking system components. No other system on the market today comes close to the performance or convenience of the Smi system. Features Dual-signal proportional control (MSI) which gives the driver the same brake feel at any speed. This allows the driver to brake smoothly at any speed. The forced braking action gives the driver the same brake feel without the added pedal travel needed at higher speeds. The force needed to brake safely to avoid runaway vehicles is also built into the controller. Features Flexball actuator mount 75percent smaller than competitor models.
