Works great on my Peterbuilt 330 set up with a 12' flatbed with gooseneck and 2" receiver hitches. The electric trailer brakes actually work when you expect them to. 340715

Ask the Experts about this Hayes Brake Controller
Do you have a question about this Brake Controller?


  • Can a RV with Air Brakes Have an Electric Brake Controller Installed
  • That's actually what we recommend the most for people towing trailers with electric brakes that have tow vehicles with air brakes. Installing a P2 part # 90885 will allow you to totally bypass having to interface with the air system and will work very well. Hardwiring a brake controller isn't too difficult. It basically is just a matter of running a few wires. One to the positive post of the battery, one to the ground, one to the trailer connector, and then one to the stoplight circuit. I...

  • Brake Controller in a Volvo 780 VNL Semi for Towing Trailer with Electric Brakes
  • Since your Volvo 780 semi has air brakes the part # HA100400C that you referenced would work well as it is designed to tap into your air brake system and apply a proportional amount of braking power to your trailer's brakes as it senses coming through your air brake system. If you are looking for the best option this is what I would go with as it's going to give you a way to apply the same amount of pressure as your semi brakes are applying.

  • Where Does Stoplight Circuit Get Sourced for Install of Hayes Brake Controller HA100400C
  • Actually when you wire in the Hayes Brake Controller part # HA100400C you use the vehicle's wiring and not the trailer wiring. You would need to find a stop light circuit for the red wire of the controller. Typically this is found at the brake pedal switch or in some case the wiring to the third brake light is used. I attached a help article on brake controller installs for you to check out as well.

  • Recommended Electric Over Hydraulic Trailer Brake Conversion for Dual 10K Axles
  • The Disc Brake Kit # K2R1058D13 by Kodiak is the brake set that you will need to use for your 10,000 lb Dexter Torsion axles. When it comes to hardware, like the brake line, I recommend going with the Kodiak Hydraulic Brake Line Kit # 24TA-BLKIT which will wear better than other traditional brands. These lines are very flexible so the line is easy to maneuver under the trailer. The only downfall is that you cannot cut the line due to how hard and risky it is to do yourself. All you have...

  • Brake Controller Recommendation for a 2016 Fleetwood Expedition 38k RV
  • You have a couple options. If you want a brake controller that taps into the air brakes of your RV to send a proportional amount of braking power to your trailer's electric brakes you would want the # HA100400C. Or if you didn't want to mess with tapping into the air brakes an easier install would be an electric brake controller. I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to...

  • Parts Needed to Wire Prodigy Brake Controller in Peterbilt Semi Pulling EOH Trailers
  • We do offer brake controllers such as the Hayes Air Actuated Trailer Brake Controller # HA100400C that takes in air pressure and converts it to an electrical signal for trailer brakes, but this item is not compatible with electric-over-hydraulic brakes, only electric drum brakes. For your application I suggest the Prodigy P2 # 90885 that you referenced. It has a setting for EOH brakes. You will also need an installation kit # ETBC7 to enable a hardwired installation. The challenge will...

  • Brake Controller on Tow Vehicle with Air Brakes
  • The Hayes Air Actuated Trailer Brake Controller # HA100400C is designed to be used with a tow vehicle that has air brakes. However, that doesn't make it your only option. Electric brake controllers tie into the stop light switch of the tow vehicle so it doesn't matter what type of brakes it has. For an electric brake controller I suggest the Prodigy P3 # 90195 because it's one of the most reliable and easy to use brake controllers on the market.

  • Mounting Bracket Installation on Hayes Air Actuated Trailer Brake Controller # HA100400C
  • The U-bracket included with the Hayes Air Actuated Trailer Brake Controller # HA100400C is intended to support the controller from below and attach to the bottom of the dash. It does NOT attach to the controller in the way that typical brake controllers like the Prodigy P2 # 90885 do. The installation process of the Hayes controller includes application of double-sided tape, which is then followed by the installation of the bracket. It may be necessary to slightly adjust the shape...

  • The Hayes Air Actuated Trailer Brake Controller - 1 to 4 Axles - Proportional # HA100400C mounts to the inside of your 2007 Nemar Essex at the dash just like other electric brake controllers will. It needs to be installed on the inside of the vehicle for proper function. It has a slide bar override that needs to be within reach for emergency trailer braking. The wiring connects just the same as an electric brake controller. Blue is trailer brake output, red is stop light swith, white...

  • Why Would Hayes Brake Controller # HA100400C Have Voltage on Output Circuit All the Time
  • Sounds like the red wire of the # HA100400C is connected to a circuit that has 12 volts all the time. You need to make sure it is connected to a circuit that only sees voltage when the brakes are applied.
