Invisibrake quit working

[ceudaly]

My Invisibrake 8700 system has stopped working. The system is wired to separate bulbs and no diodes are used.

The symptoms are as follows:

Apply brakes in motorhome both toad brake light come on and the compressor turns on.
Pressure gauge reads about 60 psi

The brake pedal does not move and the slack in the cable is not taken up.

I don’t have a way of verifying that the pressure is actually being sent to the slave cylinder.

Any suggestions?

I have an Invisibrake and while I can't give you a specific answer I can suggest you refer to the owners manual and give Roadmaster a call and talk to them about your issue. They can probably help you.

Wish I could have been more help..
