brake problem

[JaycoJohn]

I'm setting up my 2006 CR-V for flat towing behind my motorhome. Installing Invisibrake supplemental braking system. Hooked up all the wiring and hardware. Tapped into the vacuum lines. Had done everything except the monitor lines. When I tried to move the car, I engaged the brake pedal, started the car as usual, but it wouldn't move. I discovered the brake pedal was fully engaged, wouldn't retract and wouldn't let the car move.

First thought was Invisibrake was engaged, but not the case (slack in the cable). Then discovered the vacuum hose had pulled out of the back of Invisibrake control unit. Plugged it back in, buy nothing changed.

I suspect something to to with vacuum lines, but rechecked installation and everything looks good.

Any help I would really appreciate!

Glad you got it working and thanks for sharing the solution!

Called Roadmaster (couldn't call until Monday) yesterday and they suggested I make sure the brake light switch was adjusted correctly. I didn't even know it was adjustable. I took it out to check wiring for monitor and inserted it back in all the way which pushed down on the brake pedal. Simply fix. One of those "feel like an idiot" situations, but easy fix anyway.

thanks for the suggestions.

Wish I could help, but if you haven't yet, I'd reach out Roadmaster

I was going to say if the car shifter won’t move, check for brake lights, then the 15a fuse under the hood. The vacuum fitting definitely needs to be in the right direction as it is a one way valve. I know my Invisibrake pulls the brake pedal part way down when activated. If it goes a long way down, there would probably be some slack in the cable. The cable is the only connection to the brake pedal so try disconnecting it and see if that changes things. Good luck.

Will now shift out of park. I forgot to plug brake light switch back in. But will still NOT move.

Now in addition to brake being depressed, vehicle won't shift out of park.
