Description Instructions
 
The Smi Stay In Play Duo is one of the most unique braking systems on the market today. There is currently no other system that features an out of the way, soft pedal proportional braking design that fits every towed vehicle on the market. Another one of a kind feature is it's dual-signal activation eliminating the chance of the system activating when you do not want it to. Activation requires deceleration and the application of the motorhomes brakes to instantly and proportionally apply the towed vehicles brakes. The Duo system energizes the towed vehicle's power brakes without the engine running, so you have a soft brake pedal. The DUO replenishes the vacuum in the car's power brake system. By replenishing vacuum, gentle smooth pressure is applied to the towed vehicle's brakes. With the power brakes active, only 10 - 12 pounds of pressure is required to provide a gentle smooth stop. This system comes complete with everything you need for installation including a breakaway system and step by step installation DVD.
  • Hidden installation under the hood of the tow car.
  • Air cylinder only apply 10 pounds of force
  • Automatically applies proportionate and progressive brake effort.
  • Panic stop braking feature
  • DUO is always ready to tow.
  • Two signals are required to activate the system
  • Operating unit installs under the hood and out of the way
  • Fits every tow vehicle
  • 5 year warranty

Stay IN Play Duo Braking System


Additional Product Information
The SMI Stay in Play DUO utilizes air pressure and vacuum to give you the fastest most powerful self contained supplemental brake ever. Duo uses the power and speed of air pressure to activate your towed vehicle brake pedal while creating vacuum for the power brake system. These two features combine to create the only progressive and proportionate vacuum assisted system with total control. Duo requires BOTH deceleration AND coach brake lights to apply the towed vehicle brakes. By combining two separate signals the need for complicated electronics is eliminated, which provides you a more reliable long lasting system. In addition, DUO is the pioneer in user friendly operation; "Just Turn it on...and Tow." This simple technology was first introduced in 2003. Tried and true, DUO does not have to be taken in and out for normal operation of the towed vehicle. Unhook the car and drive off, thats all. No box, no wires, in fact, no physical connection to the motorhome at all.

The Stay-IN-Play DUO system energizes the towed vehicle’s power brakes without the engine running, so you have a soft brake pedal. Once engaged, DUO replenishes the vacuum in the car's power brake system. By replenishing vacuum, gentle smooth pressure is applied to the towed vehicle’s brakes. With the power brakes active, only 10 - 12 pounds of pressure is required to provide a gentle smooth stop.

Activation of the towed vehicle's brakes require BOTH deceleration and the brake lights from the motorhome. Once BOTH signals are present, DUO gently applies the brakes. There is no complicated gain or sensitivity to achieve the proportionate balance of brake effort, it is all automatic. Automatically, once engaged, DUO will apply progressive brake effort in the towed vehicle. Because DUO uses both brake lights from the coach and deceleration, there is absolutely no delay. This becomes critical in a panic stop. Systems that use only deceleration must "think" first, is this a step grade, is this a large bump, or is this stopping? Time translates to feet while towing and in a panic stop, inches are important. No self contained system applies brakes faster than the DUO.

Coach Notification is another important aspect of any supplemental brake system. Some claim to have it, but really do not; while others do not really tell you about the position of the brake pedal in the towed vehicle. Without question, the most important information while towing is the status of the braking system in the towed vehicle. "Are the brakes applied?" That is the question. When researching brake systems, ask the question, "Do you have coach notification FROM THE TOWED VEHICLES BRAKE PEDAL SWITCH?" Many will claim to have a signal but do not, and others will have a signal from some other source. The only reliable and complete signal must originate from the towed-vehicle's brake switch. If the light is on, the brakes are on, period. What you do not want is a problem while you are towing. Knowing the position of the brake pedal gives you that peace of mind.

Simple on/off towing, the gentleness of vacuum, the speed and power of air pressure, dual signal activation, and reliable coach notification all combine to provide the most powerful easy to use system available today

This system was suggested by April 30, 2015
Reviewer: Pete V.  
This system was suggested by my friend, who has a shop and is installing it for me. He has the same system on his toad except his is air operated.
RVupgrades took my call and answered all my questions with expert advice. Placed order over phone and was shipped fast!!!!!!!
Excellent service, best price i could find. I did check pricing for about a week and this SMI DUO braking system doesn't seem to go on sale really.
I will buy from them again, super fast service.
Thanks RVupgrades.

The Stay-IN-Play Duo Braking System October 15, 2014
Reviewer: Larry E.  
The Stay-IN-Play Duo braking system was delivered quickly and at the lowest cost I found on the internet. I installed the system per instructions in a Ford Ranger and it works as advertised. I would buy the same product again will consider buying from RVupgrades in the future for my RV needs.

Stay-IN-Play with 2014 Ford Focus February 14, 2014
Reviewer: Dean M.  
A great product!  A little tricky for the installation in the Focus, but worth the effort.  Flip a switch and tow it away.  First tow was yesterday and everything seemed to work as advertised.
