Tow your fifth-wheel trailer with your air-brake-equipped semi or truck. This air-actuated trailer brake controller senses the amount of pressure you apply to your vehicle's air brakes and applies the trailer brakes proportionally.

Specs:
With a conventional electric brake controller, hauling a fifth-wheel trailer with a semi or truck that has exhaust brakes can be a challenge. Whenever you're going down a long downgrade and you engage your exhaust brakes, the brake controller could turn on too. If that happens, all the way down that long hill, the trailer brakes will stay engaged and potentially overheat. This will wear down your brakes a lot faster. You'll have the same problem if you put your hazard lights on, with the brakes pulsing with each blink. You could really dig into your wiring and do some splicing to fix this problem. Or you could get the Hayes air-actuated brake controller and have smooth, flawless braking with a controller made for air brakes.
The Hayes air-actuated brake controller gives you proportional braking for the best towing experience. Proportional braking means that your trailer brakes mimic your tow vehicle's brakes. If you slam on the brakes in your vehicle, your trailer brakes will activate with the same intensity; if you brake lightly, your trailer brakes lightly too. The trailer's braking is in proportion to your vehicle's braking. This saves wear and tear on the tires and the brakes on both your vehicle and trailer.
This air-activated controller ties into your vehicle's air brakes to sense exactly how much pressure you are applying to the brakes. It then sends a signal to the trailer to apply the brakes with a matching amount of force. The result is uniform braking across your towing setup. No push-pull action just smooth, proportional braking every time.

ON A 2018 FRIEGHTLINER CASCADIA WITH A 45 FOOT GOOSE NECK
Well, my first attempt to put an electric brake controller on my 2018 Frieghtliner cascadia was complete failur. I used an agility brake controller first when it was complete it kept flashing 10 when the brakes were applied, do your self a favor and waist of money don’t try to install one of the brake controller you get at advance or O’riellys they wont work on a 2018 but will work on 2006 Frieghtliner but here’s the thing i suggest going to extra mile and buying this hay’s air brake over electric and over electric over hydronic which’s is what im using with my 2018 Frieghtliner after dragging this trailer around for at 6 months not relaxing the brakes wasn’t working on the trailer.
Fast forward to Monday 10-10-22 i called and ordered this air brake over electric part number 100400c had the mechanic do install for me ooooooooooooh sweet sweet music to hear that break away brake system fire up and apply the brakes for the first time in a 6 months was bliss.
Ordered 10-10-22 received 10-14-22 package was damaged and wet BUT WAS NO FUALT OF ETRAILER’S damaged in transit by usps, all parts was still in box went to install it.
On my install we hooked all wires accordingly like the instructions says to son the air connection part we cut a corner, on the install the instruction says to use a dual check valve to install the air line we only counted to the mail supply air line tested for air when applying the brakes got the correct line put a t connecter inline connected the 1.4 inch air hose ran through body hole connected to the hays controller tested the brakes and then the music started playing.
BOTTOM LINE IS YOU CANT GO WRONG IF YOUR TOW UNIT IS AIR EQUIPPED AND YOUR TRAILER IS ELECTRIC OR ELECTRIC OVER HYDRAULIC
We have electric to hydraulic trailer brakes and struggled with the top of line proportional electric brake controllers. With Hayes air to electric the trailer brake controller application is consistent and very effective. I have the Hayes in two of my Freightliner M2-112s and love them.
Do not buy this controller! It is an absolute joke.
Per e-scammers product description the light is supposed to change as you adjust the power. Below is the response from Hayes:
Hi Justin,
The light is just an on/off indicator light. It does not change intensity with the output.
The nob only reduces the maximum output by about 3 to 4 volts when turned all the way in the other direction.

When you adjust the knob there is no positive feeling of adjustment, it just feels like the knob itself is threading off. When I first installed it worked well until it burned up the brakes on my big Tex trailer.
Know when you purchase this etrailer will take your hard earned money. When you have a problem they will not give you the time of day and refer you to Hayes. Hayes is no help as shown above.
This is false advertising by etrailer and is not right. I strongly advise you think twice before installing this on such a huge investment.

Justin - 08/29/2023This part will be a game changer for us!!
Thank you etrailer!!
I bought this item and it turned out broken. I emailed etrailer and they rejected request to return broken item and redirected me to manufacturer. Do not buy anything from them because this is a Scam!
Katrina B - 03/08/2023It's the simplest way to add electric brakes to an all air vehicle.
Needed a brake controller for my RV hauler conversion. Worked great and very easy to install. Received quickly and staff was very helpful!
the order showed up today and have someone starting to install it nice to find one that works off air pressure
Definitely a great product! Easy installation and great instructions! I use my semi to pull my camper occasionally and this box works great for the electric brakes on the camper from the air brakes on my truck.
Works perfectly exactly what I needed for an old school pre electronic all mechanical k100 aerodyne. Thanks
Part is exactly as described and my customer is happy! Very fast service.
easy installation
This is an excellent way to provide proportional brake energy to trailers with electric brakes.
Well designed, reasonably priced.
Installed in 2002 Peterbilt 320 with air brake system, for use on electric over/hydraulic trailer brakes system. It works great!
Pate. - 02/18/2021 Pate. - 02/18/2021Good quality actuator.
Works great. Customer service was above and boyond helpful. 100% excellent. Thanks for a great product!!!!
the information provided with the is stall is very veg they could have told you where
to get a check valve they could have showed you in detail how and where to hook
into the air valve , what lines to hook into , or offed a video on how to install
for what it cost it is a rip off, you need to let hays know this for future sales
Mike L - 04/09/2019Fast delivery but would have been nice if it came with everything needed to install. But looking forward to installing and seeing how it works
Very nice unit. Have not installed yet. I will say it would have been nice if the sight gave you options for those Cesery‘s you could use…. Check valve, colored wire ect. I will review after install.
Great service
Installed and tested but not yet used. The controller is of very high design and build quality. For the air connection, all I had to do was tee into the air line that goes to the brake light switch which already has a double check valve in place.
I have not hooked up the unit yet. I have an overland osprey diesel pusher(dp). The coach has an exhaust brake. When the exhaust brake engages the brake lights automatically come on. Using a conventional electric brake controller like the Prodigy
P2 would engage the trailer brakes when ever the exhaust brake engages, causing the trailer brakes to burn up on long down grades. I know this can be fixed by adding a diode in the wiring, but that involves tracing a lot of wires until I found the right one. this unit doesn't need to connect to the brake lights. it only needs the air pressure being applied to the brakes to engage the trailer brakes. It really is a sweet unit for a DP with air brakes.
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.
Hard to adjust and you can't test the trailer brakes with it. Never fells like the trailer is getting power to activate the trailer brakes even though there's 12 volts going to the brake wire
Purchased this for a Class 8 truck with air brakes. It was easy to mount and to install. Wiring it up was a snap, but I was surprised that I ordered 2 and did not receive instructions with either. Had to go online to get a schematic and operating/mounting instructions. Wasn't a big deal as etrailer had it on the product description, but if you're old school like me you expect to receive instructions with the product.
