Is there any way to "test" the Invisabrake system to be sure it's working? Yes, the little light on the dash does come on when the brakes are applied indicating it's working. I never feel any difference in the braking when I'm towing, is it really that smooth that I can't feel any type of "surge" from my toad? Any suggestions or thoughts on this?

There are recommended pressures for most vehicles. You can watch it work by having someone hit the brakes when parked and see the pressure and brake pedal motion. Some use the breakaway to do that. I have two momentary contact switches that when both are depressed will fire the controller.

If you are getting a brake indication and the unit is correctly installed, that means that the pedal is being depressed and the brakes should be applied.

If you don't think it is applying enough braking, you can increase the amount of pedal pressure by adjusting the air pressure.

Step on the coach brakes and have someone watch the gauge on the unit and adjust the pressure up.

Thanks all for your replies. I will have someone assist me and check out the suggestions. As I mentioned, if it's working properly, it is the most synchronized system I've seen as there is absolutely no indication that it is breaking before the motorhome is. However, that might be the case as it is suing the toads brake system rather than and electrical braking system that is on most travel trailers and fifth wheels.

It can't brake before the motorhome since it uses the voltage on the motorhome's brake lights to initiate breaking. Unless your motorhome brake lights come on before it applies any braking on the chassis, which is probably possible although only for a very small time interval. Unless your motorhome brake pedal has a lot of play...

If all above efforts fail to satisfy your question, you might ask a good friend to take a ride in your toad while you take him on a ride around the island. Then you will have his opinion of how it is working.

If he is a really good friend totally above question, you might have him drive you around the island while you ride in the toad and you'll have first hand information on how it is working. This would probably be my approach.

I once wanted to ride in our travel trailer so had the DW drive while I rode, a corner came up a little faster than she expected, electric brakes came on and we made the corner just fine, WOW, never did that again

That is sort of the way I decided that Blue Ox controller didn't work. Put it on the pasenger seat and drove around. It never fired...

If you make adjustments, watch your front brakes for excessive brake dust, an indicator that you've adjusted it too much.

For systems that move the brake pedal, I think it would work to set up FaceTime (iPhone) or Skype (Android) between two cell phones. Put one in the toad, camera pointed at the pedal and secured against movement, and the second in the coach. Sort of an ad-hoc closed-circuit TV system.

If you have the recomended Roadmaster brake light and warning buzzer it shows the brakes are working. You need to read a Roadmaster manual.

This kit tells you by the red light in your Motorhome when the brake pedal is depressed and when it is not on.

The red light on your dash should possibly be part of the kit. You might want to check or adjust your pressure there again it is in the manual.

From the OP "Yes, the little light on the dash does come on when the brakes are applied indicating it's working..."

If this is true, your unit is correctly installed and the pedal is being depressed. You could up the pressure if you want, but don't overdo it.
