Larry Burkett Posted June 29, 2020 Report Share Posted June 29, 2020 I am having a problem with the brake actuator i believe. We have a 2006 NUWA Champagne with electric over hydraulic disc brakes. When I hook up to the trailer and plug in the cord to the truck everything is fine, but when i push the brake peddle, you hear the actuator start buzzing and it does not stop even when you shut off the batteries. i have to disconnect the batteries for it to stop. Hook the batteries up and no buzzing. I can tell it is putting some brake pressure on as it pulls harder than before. Any ideas would be appreciated.

Larry Burkett Posted June 30, 2020 Author Report Share Posted June 30, 2020 Yes, i replaced the breakaway switch a couple weeks ago because it was loose. Quote Link to comment Share on other sites More sharing options...

Did the buzzing start after you replaced? If so we can narrow it down to a faulty unit purchased or a mistake in installation. Quote Link to comment Share on other sites More sharing options...

rickeieio Posted June 30, 2020 Report Share Posted June 30, 2020 Shooting from the hip here, but is almost sounds as if there's a relay somewhere in the circuit that's not releasing when you let off the pedal.

Larry Burkett Posted July 1, 2020 Author Report Share Posted July 1, 2020 i'm thinking of that, but we have pulled with this truck since we got it in August 2019. Quote Link to comment Share on other sites More sharing options...
rickeieio Posted July 4, 2020 Report Share Posted July 4, 2020 Just a random thought...... Try plugging in your electric connection, apply the brake, then unplug the cord. If the pump still runs, something is back feeding the pump. I'd start by checking EVERY terminal in the plug, both male and female. Use a DVM set to ohms and see if there's a connection where there shouldn't be. A single strand of wire in a plug can do weird things.

Larry Burkett Posted July 5, 2020 Author Report Share Posted July 5, 2020 I will do that tomorrow, but yes it keeps running after the cord is unplugged. Fluid was low in the reservoir, so i topped that off til it stopped taking more fluid, and it was over 6oz. Quote Link to comment Share on other sites More sharing options...
Larry Burkett Posted July 24, 2020 Author Report Share Posted July 24, 2020 Well, after taking it to a shop to have it looked at to figure out the problem, the mechanic said lets call Dexter to see if they had any ideas. we talked to the tech there and they said there is a computer board inside the actuator , and it was bad. You can't buy that, you have to buy a new actuator, so $700.00 and an hours work , everything is working again. Quote Link to comment Share on other sites More sharing options...
