Issue: Actibrake system shuts down

[hookedonclassic]

A problem that I had last year several times occurred again about two weeks ago. I am wondering if anyone with hydraulic brakes using Actibrake system has had this issue before. Here's what has happened and what has been done so far. For now the issue has been resolved with a new brake controller (P3).

I had been using a Brakesmart brake controlller with my 2006 34' with the Actibrake system. Three or four times last year, I would lose brakes on the trailer (both pedal and manual level) without notice. The trailer brakes could be restored by disconnecting the power from the TV and disconnecting the 2 coach batteries. The Actibrake would reset itself and be fine. One could go days or weeks before the issue occurred again.

Last year I had the factory check it out and they recommended replacing the brake controller with one listed on the approved Actibrake controller list if it occurred again. I didn't do that until 2 weeks ago after it happened again. This time it was after 3,000 miles towing and about 12 days of travel.

The P3 seems to work well up to this point but the jury is out to see if the Actibrake will still shut down with the P3. I've talked to Dr. Performance who sells the Actibrake and they have not had a similar situation before.

Yesterday, I had the brake pads and the rotors replaced on my TV, 2004 GMC 3/4 ton with 87,000 miles because they were shot. I don't know it that was excessive wear or not but the lack of trailer brakes may have be a factor or I may have had the gain on the trailer brakes set too low. The P3 is easy to set up and I can feel the trailer brakes take hold more so then the setting I had on the Brakesmart.

Has anyone had a similar problem with the Actibrake shutting down. I know it will do so with a leak in the line but I doubt that is the issue since it can work for days or weeks without an issue.

I'll post an update if the problem reoccurs with the P3 controller. Then I'll know that the Actibrake is the issue and not the controller.
