Roadmaster InvisiBrake vs other braking system
I am in the market to get my toad hooked up to my RV. I am looking at the Roadmaster InvisiBrake system, but I have heard that it engages when using the exhaust brake. Their website addresses this, but I am not sure I like the 15 seconds they mention. Anyone have experience with this or would like to recommend a better system?
FAQ on Roadmaster InvisiBrake website.
"My motorhome has an exhaust brake. Will it cause InvisiBrake to self-activate?
Only if the exhaust brake makes your brake lights turn on. In this event, InvisiBrake protects the towed vehicle by automatically releasing after 15 seconds of continuous braking. InvisiBrake will work normally with your next braking activity."
My first thought is 15 sec. is a long time, but then considering coming down a mountain or other long inclune and15 sec. is really not that long.
Thanks in advance.

I thought , I had info on all brake systems, can't find anything on Invisibrake  , and because of the activation of brake lights with the exhaust brake ( my coach has this feature ) , I was looking at Roadmaster's Brake Master , air activated system.
If the Invisibrake , control takes a feed from the brake lights and your coach activates the brake lights with the exhaust brake , the installation of a diode , so that only a feed from the brake light switch goes to the controller, can eliminate the 15 secs of braking at exhaust brake activation.

Just back from the Roadmaster web site. Because of where the Invisibrake controller picks up it's activation signal , installing a diode where I had thought of ; for other systems ; will not work, on this one.

The RVi system is self contained so it doesn't care if your brake lights are on or not.

That had been my ; best of the electronic ; choice.
Auxiliary Braking System, RV Towing, How to Tow a Car, RV Brake Parts & The Brakebuddy | RVi Brake
I think the OP was after a system that didn't require anything be moved to drive the toad.
But the rvibrake wins on, first time , install time.JMHO
OUCH, price increase.. in the big tent at Quartzite in Feb, they were less than 1k.

I use the RoadMaster BrakeMaster 9160, it is activated by the air brakes on your coach and is truely portional braking. It only activates when you press the coach brakes, and it's easy to install and remove, less than 1 minute. I've had mine for 4 years, the only other unit I would consider is the M&G unit, but they didn't make one for either of my last 2 toads.

If your exhaust brake activates your brake lights, yes, you deal with the 15 second braking. If the exhaust brake doesn't activate the third (upper) brake light, which only comes on with the service brake, have the installer tap into that brake light. I have the InvisiBrake on my Vectra, and had I known I would have had them wire it that way. I do like the ability to adjust the compressor to increase or decrease the braking pressure.
