Video Transcript for Hayes Brake Controller HA100400C Review

Speaker 1: Today we're taking a look at the Hayes air-actuated trailer brake controller. The brake controller activates your trailer brakes in proportion to your vehicle's braking action. It activates immediately so there's no pausing, like with time-delayed brake controllers. The air-activated controller ties in to your vehicle's air brakes to sense the amount of pressure that you apply to the brakes, so thus, you don't automatically adjust the trailer's braking based on how you depress the brake pedal in your tow vehicle. The rate of brake application can be increased or decreased by turning the controller handle. Also, right here, there's a red LED indicator on the front of the unit that shows when the trailer's brakes are applied, and the light will glow brighter as trailer output increases.

The unit also features hazard flasher immunity that prevents pulsing of the brakes when flashers are activated. It does have the slide bar manual override. It's a nice, compact controller. Has a black textured finish to it, metal construction. It also comes with the mounting bracket and hardware to get it mounted, so it would basically just sit like this, and then you can mount it in a convenient location with the included hardware.The product is made in the USA.

It's designed for tow vehicles with air brakes and trailers with up to four axles or eight brake assemblies. This is designed for use with electric brakes or electric over-hydraulic trailer brakes. When it comes to wiring, the white wire is the ground, black wire is the main power wire, and then the red wire goes to the brake light switch, and the blue wire is positive power to the trailer brakes.A few measurements to go over with you real quick. Overall length from this point here to this point here measures about 8 1/2 inches. Overall width, side to side, is about three inches, and the overall thickness is about one inch.

Then when it comes to the air input port thread size, we're looking at 1/8 inch MPT.That's gonna do it for today's look at the Hayes air-actuated trailer brake controller.

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?


  • 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 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.

  • 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...

  • 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.

  • 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 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...

  • 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...

  • 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.

  • Brake Controller Recommendation for Vehicle with Air Over Hydraulic Brakes
  • Easiest solution to activate electric trailer brakes is an electric brake controller. Even though you have a different style of vehicle brake system than most vehicles an electric brake controller doesn't "care" as long as you have a 12 volt system and can find a signal wire that only carries 12 volts when the brakes are applied this would be the easiest solution by far. For a brake controller I would recommend the Prodigy P3 Brake Controller part # 90195. This is our best selling brake...

  • 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.
