Most Popular Proportional System for Chevrolet Sonic

I mounted this in a 2014 Chevy Spark. Finding a spot for the main control unit was interesting, but I found a video for a 2017 Spark that I could use. I did have to drill an extra hole in the mounting flange and car. I haven't taken it on a trip as of this time, but a tow around the block indicated it was working. One note, watch about placing the LED indicator behind the tinted part of the toad window. It makes it harder to see from the camper camera.

Ordering was easy. Delivered very promptly. Actually cheaper then what the manufacturer sells it for. Live near manufacturer and having them install all my flat towing components this month. Great service Etrailer!!

Very happy I received it, normal great service from etrailer but had a shipping issue, (shipper's fault). I will always go through etrailer first for anything RV related. I will be back!

I wouldn't use anything else! Once this system is installed it's literally plug-and-play. Nothing to move or install into the car, each time you tow. Just plug it into the coach's air break system and you're done. Install video from etrailer made it even easier to complete. You do need a bit of mechanical guidance/assistance as you're connecting to both your vehicles and coaches breaking system but it has worked flawlessly for over 11,000 miles and in some pretty intense traffic.

If you have air brakes and tow u need AF 1 I self installed and it works great nothing to remove from drivers side from brake pedal just normal hook up plug in air hose ( blue) and connect brake away cable and go only issue I had with install is my toad (Chevy Colorado) requires battery disconnect well I had my disconnect hooked to the negative post well that didn’t work , the brake system needs power to function so 1phone call to Demco! fixed it hook up batt disconnect to positive and it now works

The install on my Ford Maverick is clean and functional, so this is more of a customer service review... excellent customer service! During the 4-day towing set-up install, the forecast was for freezing temps and my rig was not winterized. I called in mid panic and the motorhome was moved indoors. A few months after using the tow set-up, a minor problem developed. I called and the CSR apologized and said, I can see how that might be frustrating, and a replacement cable (slightly longer) was sent free of charge.

Second set on second Jeep, Brake system works great, a bit of an install with the air lines and placement of the small tank in the crowded engine compartment BUT once it is in the setting of the brake peddle arm is easy!

I am a proficient DIYer (and was an auto mechanic many years ago). The installation took a lot of time - perhaps 8-10 hours for the brake controller. The most special tool needed was a rotary cutter (e.g., a Dremel tool). A cordless impact driver was also very helpful, especially with the self tapping screws. Getting the pully in the perfect position under the brake pedal took some trial-and-error to get perfect. Also, the included bolts for the brake pedal bracket where too short to accommodate the width of the brake lever - easily remedied with slightly longer standard bolts. Be very mindful of what is on the other side of the sheet metal you are planning to drill into. The brake supplemental vacuum system was a bit of a challenge, as the instructions are very vague regarding how to mount, and the space I had to work with was surprisingly tight. I ended up creating a mount on the inside front fender, and bolting the pump to that. Also, tapping into the vacuum lines took a couple of tries to get a leak-free connection. Think ahead about this, and be prepared to get a few small parts like hose clamps or right-angle hose connectors. This would be a potential consideration for any vacuum boost added on any vacuum power-assist application with any controller. I mounted the Brakebuddy main unit under the rear seat - that was a perfect location, and much better than the often suggested location under the driver's seat. I was very pleased with the installation result. I paired this with a Nighthawk tow bar. Be warned that the tow bar's included cable will not be compatible with the Stealth, as the Brakebuddy uses a proprietary connection at the towed vehicle. The upside of this proprietary connector is that all connections are build in, including the brake away cable and the battery charging line. (I modified the Nighthawk by replacing the included cable with a 4-pin cable to power the lighting system on the bar. This is just for extra safety and cool looks - I could have just not used the tow bar's included cable). With 1,200 miles of towing behind us, I can say I am very pleased with the performance. I rarely notice any difference in braking effort or effectiveness - which is a big advantage for a proportional system. My favorite feature is the ease and speed of connecting or disconnecting the towed vehicle. I'd give this a 4.5 stars out of five if I could, because I did need to add a few parts and make a couple trips to the hardware store to complete the installation. However, the excellent performance and ease of use once installed more than makes up for the inconvenience during initial installation. Special appreciation to the people at eTrailer, especially Nicole T, who provided support and guidance from pre-sales to installation. Also, I called Brakebuddy's support line with a concern, and they immediately picked up the line, addressed my question, and offered to immediately ship any parts if needed.

I choose the Brake Buddy Stealth for my 2021 Jeep Wrangler because I wanted a “stay in place” brake system and felt it would be a clean looking installation. I finished the toad side of the installation today and thought I’d leave some notes on what turned out to be a bigger project than I’d anticipated. Again, this is my experience on the 2021 Jeep Wrangler 2-door. Your experience on other vehicles may vary. I started this install after installing a Demco Tabless Base Plate. Right out of the blocks, there’s really no convenient location to mount the cable connector to the Demco baseplate. I chose to mount it to under side of the bumper on the driver’s side. To provide clearance and a route for the wires, I had to cut a notch into the plastic air dam. I used one of the already screw screw holes and used self tapping screws in the other three locations. For added strength I epoxied the connector to the bumper as well. Since the bumper would be unremovable if the connector were hardwired, I added a waterproof connector. The kit is stingy with wire lengths, so I substituted my own wire. The Stealth unit itself i mounted beneath the driver’s seat. Don’t be fooled into believing there is clearance when testing with the driver’s seat positioned for rear seat access. Once the seat is returned to normal operation it lowers a bit and the box keeps the seat from being move forehand aft. I solved the problem by installing 5/8” thick nylon washers under the rear end of the seat slides. I also cut away a bit of the carpet under the front, inboard corner of the box. You will need to remove the driver’s seat in order to attach the front screws of the box. Be sure to disconnect and isolate the neutral battery terminals to prevent inadvertent air bag discharge. After removing the interior trim from the A-pillar, the door sill, and the driver side foot well, The wiring and cable tucked nicely away along with the OEM wiring and wiring for my taillights. I mounted the pulley horizontally behind the brake pedal. Installing the vacuum pump was my biggest worry and challenge. Instructions are to zip tie it “somewhere”. That seemed pretty casual for a safety system. I chose, instead, to fabricate an aluminum bracket that attaches to the lip of the engine compartment and to the wheel well (this latter attachment point is necessary to keep the pump from vibrating). Finally, the kit comes with 3/8” fittings to tap into the brake booster vacuum lines. The Jeep, however, uses 8mm nylon tubing. Brake Buddy, via etrailer.com, stated that the tubing would stretch and all would be good. Again, this felt casual for a safety system. Instead, I purchased an 8mm check valve and a 8-6-8mm barbed tee through Another online retailer to do the job right. I had to heat the Jeep tubing to fit even the 8mm tee, so the is no way the larger 3/8” fittings would have worked. See photo of my finished vacuum line installation. Bottom line, it was a POA install, but looks great. Hopefully it will stop the Jeep when towing. I’ll find out soon. :D

Had a problem with the connection to the unit but called etrailer and they sent me a new one after sending the other back to them. The hole process very painless and the the staff at etrailer was great to work with. Thank you etrailer for your great response.

I am still scratching my head on the placement of the Main Unit. The floorboard area of the 2024 Jeep Wrangler is very small. The 2 levels of the rear of the unit are such that I can't seem to get the right height to stabilize the unit. The seat can be brought slightly forward but does not contact or even come close to the Handle when raised. With the plunger all the way in, there is hardly one half (1/4") inch of clearance before beginning to press the brake pedal. I can't find anyone else that has installed this unit. HELP please.

It took me a couple days to get this installed,I'm not as flexible as I was so that didn't help. However I followed the instruction steps and got it done.Had to adjust the sensitivity a few times until it was the way I wanted.System works good and I get a alarm when brakes are activated. This gives you peace of mind knowing your brakes are not applied when they shouldn't be. Very Happy with it,just have to flip a switch when towing.

Installed 6/17/23 on a 2023 Equinox LT (AWD). Installation was pretty straight-forward. I mostly followed etrailer's videos. Note that the pneumatic cylinder needs to be mounted fairly high on the brake pedal arm so you have a 'square' profile to clamp onto. This vehicle has an electronic brake booster rather than pneumatic, so follow Demco's instructions regarding this variation. The wireless coachlink works great. I couldn't be happier with this system.

Kit fits great! Hooked up a 2004 Workhorse to a 2002 Jeep Liberty. It might be preferable to be handy with some advanced mechanical skills and tools to install this efficiently. Directions are great but you do need to figure out your own locations for certain items like the break-away reservoir, compressor, routing lines and wires out of harms way, but not bad at all. Parts are great, everything there but added a couple different wiring splices of my own.

Your customer service leaves nothing lacking, and this follow-up from you is so out of character for the many web sites I have purchased from over the years. I am impressed by you and your company. I bought the tow bar and the brake system for my Equinox, and installed them my self (I am 70 years old) - and with your provided instructions and video, I had no problems (even though I was surprised by the number of parts and detail that went into the assemblies). Both systems have worked very well, with no problems. I am completely satisfied with them, and have told my friends and traveling acquaintances about your company. Thanks for your follow-up!

Overall a great system, there are some intricacies to the install as it pertains to old instructions with LED light in the TOAD vs. CoachLink Wireless and also the 3 wire reed switch vs. the newer 2 wire one. But using the provided written instructions along with YouTube videos you can figure it out. My other challenge was my Jeep is a 392 model and thus the battery and fuse box are in swapped locations, as well as a different VAC line layout, but again you can figure it out…just takes some time to study and trace the routing. My only real complaint was ordering, I was quoted the wrong system for my RV (Stay and Play) vs. AF1 since I DO have air brakes. etrailer was helpful in getting the return process but wants to charge me the shipping and possibly restock fee, I am working with them on this and hope to get a good resolution.

The Air Force One Braking system just arrived. I opened the box and looked it all over. No damage to anything thanks to good packing. A friend of mine has this same braking system and he loves it. Can't give a product review because it's not installed yet but I can honestly say Dianna A in customer service helped me get my order correct.
