I have a triple axle trailer with electric over hydraulic brake on all 6. I started having trouble 2 years ago when I drove to Havasu hooked on and left. Somehow from Havasu to Vegas all the fluid drained out and I lost a hub etc. Offshore got it fixed up and off I went. So just recently I had all the bearing replaced (Vault) etc, pads all looked good, and the pump and all the lines were bled. So this weekend I tow down to Powell and the brakes are about 30% there, and I tried to hit just the trailer brake and it does not respond at all. Before I start throwing parts at it...first idea is the pump, does anyone have any ideas? You can hear the pump running etc.
