Kodiak Disc Brakes with 2013 Silverado 3500HD

I have a 2013 Silverado 3500HD Duramax and am picking up a new 5th wheel with the Kodiak Disc brake package. Will I need an acuator box or am I fine with the standard GM Brake Controller on the 2013 3500HD?
  • I remember someone saying they wired in an old brake magnet to put enough load on one of those oem controllers to make it work. I would tape a steel plate to it. Craig
  • It depends on the brake actuator. Kodiak is usually the brand name of the brake components at the wheels. The most common actuator is a Carlisle HydraStar. I think you will find the later versions are compatible with the EBC of the GM trucks. I replaced the actuator on out 5th wheel and tow it with a 2012 GMC with no "fooler" box. Check your actuator brand and model.

    Look down the page to the application table.
  • I want to thank you folks very much for the quick reply. Now I have to take action before Sunday when we head for Lake Okeechobee!!!
  • I took my 1 year old P3 from my 2004 truck and put it in my 2014 just in the last month. All wiring is under dash except you need to run a separate brake wire from the aftermarket controller to the 7 pin plug. If you don't already have a controller then the interface box is the way to go. Since my controller was so new and worked perfectly, I had the don't mess with success feeling.

    I contacted Tekonsha and they e-mailed me TB0008 which showed me the correct wires under the dash and the correct steps to separate the IBC to prevent codes from flashing up on the driver information display.

  • Yep, with GMs you need interface box to fake out the IBC into thinking it's talking to standard electric brakes. Had one with our '05 and now with the '11.
    You might check with your dealer of the RV MFR, some such as Redwood include the interface box as part of the Disk Brake package.
