Flat towing with confidence starts with the right supplemental braking system. It’s not only about safety. It’s also required by law and gives you peace of mind on every trip. RVi Series flat tow brake systems are built for dependable, worry-free performance. Whether you’re new to RV life or a longtime traveler, this FAQ will walk you through everything you need to know about RVibrake and flat tow braking solutions.

1.) How does RVibrake 3 know when to brake, since it is not connected to the motorhome?

RVibrake3 is an inertia-activated system designed to detect brakings. This allows RVibrake3 to take the weight of the towed vehicle off your motorhome every time it activates.  

2.) What if I set up RVibrake 3 incorrectly in my towed vehicle?

Not a problem. RVibrake3's Audio Assistant will alarm immediately in case of Brake Lock being detected.

3.) Will RVibrake 3 ride the brakes down steep grades?

No. RVibrake 3 applies the brakes in the towed vehicle only when you apply the brakes in the motorcoach. RVibrake3's advanced software adjusts for slope, whether you’re going uphill or down. Downshifting or using exhaust brakes will not engage RVibrake 3.

4.) Will RVibrake 3 wear down my car battery?

No, it will not. Depending on your towed vehicle's make and model, you may tow for 1-2 days without having to worry about the battery in the towed vehicle. There are two things that can affect your towed battery:  

• If you have a vehicle that requires putting your key in the accessory position with a high amp draw, we make a product called the Towed Battery Charger Plus that will keep your battery topped off.
• Life of the battery can also affect performance.

5.) My towed vehicle engine is not running. Will RVibrake 3 still have the power to operate the brakes without vacuum assist?

Yes. RVibrake 3 is specifically designed to push with enough force to overcome the absence of vacuum assist.
