Automatic Braking Action

The Brake Buddy Classic 3 has a built-in inertia sensor that detects when your rig slows down. Once the system recognizes that you're braking, it will engage the actuator arm to press your towed car's brake pedal with an intensity chosen by you.


The main unit of the Brake Buddy Classic 3 is designed to activate only when deceleration is actually taking place. It is built with advanced terrain-sensing technology that keeps the unit from activating when you go over bumps in the road. As a result, your towed car's brakes won't engage unless you intend for them to engage.


Braking Power Settings

Classic Control Panel

The braking power settings determine how intensely the Brake Buddy Classic 3 applies your towed car's brakes. When you're first setting up the Brake Buddy, choose the braking power setting that's recommended for your vehicle type, as seen on the chart below.


Vehicle TypeRecommended Setting
Cars and Compact SUVsLow
Mid-size Crossovers, Mid-size Pickups and Small SUVsMed
Full-size SUVs and PickupsHi


The setting should be enough to cause your towed car to give a slight tug at your RV during a braking event. Braking power doesn't normally need to be reset unless you're changing to a different towed car.


Note: For hybrids or other cars with power-assist brakes, switch the braking mode to Hybrid mode.


Wireless Alert System Monitors Braking Action

Classic Receiver

Included with the Brake Buddy Classic 3 is a wireless receiver that will alert you of braking activity from the Brake Buddy actuator unit. This receiver inserts into the 12-volt outlet in your RV's cab.


Classic Transmitter

A separate transmitter plugs into the actuator box to send signals to the receiver.


When the Brake Buddy unit activates the towed car's brakes, the receiver will illuminate. If the towed car breaks away from your RV, the receiver will produce an audible signal.


Powering the Brake Buddy

Instead of connecting to a 12V accessory outlet, the Brake Buddy Classic 3 draws power directly from your towed car's battery. To do this, the included wiring harness connects to your car's battery. Install the harness by routing the wire end through your car's firewall and into your engine compartment. Connect the harness to your battery with the included battery wire and ring terminal.


Mount the connector that's on the opposite end of the harness in a convenient, out-of-the-way location beneath your car's dash.


Easy-Pull Harness

To connect the actuator unit to this connector, use the included Easy-Pull harness. This harness plugs into the connector below your dash, then into the braking system. When connected, the harness carries both power and breakaway functions in a single cord. And the large grip ring and wide handle make it easy to hold while connecting and disconnecting the actuator, all without ripping connectors or pulling on wires.


If you're concerned about your car's battery going dead as you tow, don't worry. The Brake Buddy Classic 3 includes a 15-amp charger that pulls power from your RV to keep your car's battery charged while the Brake Buddy is connected.


Fast Setup and Universal Design

Not every car is built the same. Some have brake pedals with unusual shapes. Some have uneven floorboards or mats. These differences can make it difficult to set up a portable braking system in your towed car. But the Brake Buddy Classic 3 is able to fit in almost any car on the market.


Quick-Lock Clevis

The Brake Buddy's actuator arm comes with an adjustable Quick-Lock clevis, which securely wraps around your towed car's brake pedal, regardless of the pedal's size or shape.


The clevis also comes with a quick-locking lever. Once you adjust the jaws of the clevis to fit your brake pedal, turn the lever to tighten the clevis in place. And when you're done towing, disconnecting the clevis is a snap. Just turn the lever to release the clevis jaws, and remove the clevis from your brake pedal. It's that simple.


Risers Off Kilter

Uneven floorboards can cause a portable braking system to sit at an angle in your towed car. This affects the leverage of the actuating arm, which can result in ineffective braking. Each of the TruFit risers on the Brake Buddy Classic 3 actuator unit can be individually adjusted, raising or lowering each corner of the actuator unit, so that the system sits level in your car. As a result, the actuator arm is able to press straight against the brake pedal to ensure that your brakes are properly depressed every time.


TruFit Risers with Wrench

To adjust the height of the risers, twist them counterclockwise, either by hand or with the included riser wrench. Pull each riser out to match the height you need, then twist the riser clockwise to secure it at that height.


One-Touch Auto Start

Classic AutoStart

The Brake Buddy Classic 3 will automatically check your brakes every time you start it up to confirm that your vehicle is ready to tow. After setting up the unit in your towed car, press the Auto Start button on the unit's control panel. The arm of the unit will push and release the brake pedal several times, removing vacuum pressure from the brakes to prevent overbraking. The unit will also check for any connection errors.

2017 Jeep Wrangler

I purchased this BB Classic 3 in October 2020 after my old BB Classic that I purchased in 2008 failed to hold pressure for the piston. I bought this for my 2017 Jeep Wrangler but due to (1) the depth and unevenness of the driver's floor board, (2) the seat adjustment bar prevents BB Classic 3 from pushing against the seat and (3) the adjustable legs are not long enough to reach the seat and brake pedal properly, the BB Classic 3 fails the auto start test every time due to not being able to level. I talked to Hopkins MFG techs several times trying to resolve the issue (wiring checks, power cord checks, etc.) but to no avail. This situation makes the BB Classic 3 dangerous to have in service because not being level it will think something is wrong and keeps the brake applied (piston will not retract after applying the brake). So after talking to other Jeep Wrangler owners I determined that a platform was needed for the floor board on which the BB Classic 3 could rest. I constructed a platform that was approximately 3" off the floor board and rested on the floor board under the seat and on risers toward the brake pedal. This platform is level on the floor board both length-wise and width-wise. After placing the BB Classic 3 on the platform with clevis and power cord installed and legs in the lowest position, I tested the auto start and had 8 successful tests in a row!!! Also the brake away test was successful too. I still need to make a short drive test while in tow behind the motorhome. Hopkins really needs to advise customers that the Classic 3 will not work properly as is on a 2017 Jeep Wrangler due to the configuration of the driver's side floor board.


Comments
I appreciate the innovative solution to allow the Brake Buddy to work for your 2017 Jeep Wrangler. I spoke with Hopkins who did advise that it is ok for the Brake Buddy to rest against the base of the rails under the front seat.

The connection from the brake buddy to the car connection at first was great. Then, after a few times, it just got very sensitive and in some cases would not make the connection. Even when it had a good connection at first, the sensitivity was just not there. You had to literally jerk down on the brakes of the RV to get it to engage. It just never worked properly.


Comments
The loose cable that runs from the brake buddy to the vehicle is a common issue and the manufacturer is aware of it. Thankfully, it is under warranty and the replacement tends to stay a bit better. I will send a note over to customer service to have them relay the warranty notice over for you.
-- Etrailer Expert Sierra K - 10/28/2021


by:

I was required to return the brake buddy to manufacturer for repair recently because of failure to function. Shipping and repair were handled quickly. I have not tested the unit after repair yet.




by:

Purchased a year ago.
The instructions
were a little tricky to understand but we eventually got it worked out. Running the power through the firewall was difficult on the 2013 CRV.
The reason for a 4 instead of 5 is that the cable end that goes in to the Brake Buddy doesn't always keep a good connection (it has to be loosely connected to maintain power, rather than pushed all the way in) and so finding the sweet spot and hoping it will stay there while driving for hours is a little nerve wracking at times.




by:

Works well. Easy wire and set up. 4 stars as it is a little cumbersome to set up every time I use it. Company has been easy to work with any questions. I would recommend.




by:

The unit worked as it should. The original brake pedal clamp was an awful design and near impossible to clamp, after a complaint to the manufacturer they sent me the new design clamp and a new power cable. The unit seems big for what it does but funtions well.


Comments
With Braking systems, they are build to fit a variety of different types of brake pedals. Which means, they will fit most, but not all brake pedals.

Great product, had a problem with it and brake buddy overnighted a new one, great service.


Comments
3rd long trip, farthest Ive ever gone and it still works. Has had a problem on the each of my previous trips. Service is very good but really you shouldnt have to send back almost evertime you use it.

by:

I had an issue with the pedal attachment and product support staff sent me a new fixture; no charge that fixed the problem.




by:

A bit tedious setting up the first time. But after that reinstalling is pretty easy. Gives my wife and I peace of mind while traveling.




by:

It is a great unit. Very easy to install and instructions are detailed. I have used in on 2002 Honda Civic and just moved it to our 2013 Jeep Wrangler.




by:

I use the Brake Buddy quite often, is quite easy to hook up and gives me piece of mind that there is extra braking coming from my towed vehicle.




by:

Worked great first day. Second day plugs would not make good contact in both brake buddy and the dash mount. Potential for a catastrophic failure was to great, so I unplugged machine. Will be sending back.


Comments
This cord is covered under warranty. Customer Service will contact you.
-- Etrailer Expert Sierra K - 10/21/2021


by:

The Brake Buddy works well




by:

Cord for connection seems to come loose very easy,I have not tested on the road yet to see if it works while traveling, any help with securing


Comments
I recommend making sure that the Brake Buddy is siting evenly on the floor board. If the Brake Buddy is sitting at an angle it can affect the leverage of the actuating arm which leads to ineffective braking. Each of the TruFit risers on the Brake Buddy Classic 3 actuator unit can be individually adjusted, raising or lowering each corner of the actuator unit, so that the system sits level in your car. When you activate the Brake Buddy it will automatically check your brakes every time you start it up to confirm that your vehicle is ready to tow.The unit will also check for any connection errors.

Product seems to be good out of the box but haven't used it yet. A significant issue is that the installation instructions are incomplete and some connectors were not included in the packaging. Of particular note is that once you install the Dash Mount and drill a home in the firewall to put the wiring through, there are no instructions about how to connect them. I had to go to the eTrailer website where a found a video of an installation on a Jeep. The narrator did a good job of explaining the connections. Thank God for YouTube.




by:

Order arrive on time just as ordered. All my questions were answered. Alex you did a great job. Thanks




by:

Love the Brake Buddy works much better than the older models. Easy to install and quick to set up. The charging feature does away with the dead battery issue on the CRV. Bailey at etrailer was super and helpful.




by:

Great product for flat towing.




by:

Great product and great customer service from ETrailer




by:

I was in a pinch for time as I had a week before I planned to hit the road and my old brake buddy was not working properly. Roger assured me that he could get the new classic 3 to me in 4 days and he did. Haven't installed the harness yet but I am sure that I can do that in about an hour. I like the upgrades from my old model and I am looking forward to a safer trip. Thank you for the quick service

The brake buddy works very well and was easy to install. The only minor complaint I have is Pitt is the a little difficult to clamp to the brake pedal on the 2 door jeep wrangle due to space.




by:
2008 Jeep Wrangler

It was fairly simple to install ,,, once I got the ground corrected. I have yet to use it in an actual flat tow... but its simple to get in and out once its hooked up




by:
2015 Chevrolet Spark

Brake buddy customer service and help was outstanding.


Comments
Unfortunately, the colors vary in each vehicle so the wire colors in the instructions may not always be correct. The best way to know the functions of the wires is to use a circuit tester like Item # PTW2993. I have not heard the pedal size issue before so I am wondering if Brake Buddy has a solution or adapter for that.

2000 Jeep Wrangler

This item appeared to be a return, but all seems in order .... so far. I am impressed with the whole e-trailer experience. The reviews, the self help videos, the technical support (Kyle S.) and the all comprehensive customer support. Every aspect exceeded my expectation. I am an etrailer customer and supporter.




by:

Too much trouble hooking up. My old one was easy, just plug in to the 12v plug and it was ready to go.

    Great question! The Brake Buddy Classic 3 # HM39494 is a more basic system than the Brake Buddy Select 3 # HM39524 as the Classic just uses preset braking (which applies the brakes at a preset intensity when the inertia sensor detects deceleration) while Select lets you choose between proportional and full-braking action (activates towed vehicle brakes at max power regardless of RV brake pedal intensity) when you’re towing a vehicle.

This is a proportional braking system that senses how hard you apply the vehicle brakes and applies them in a proportional amount on the tow vehicle.
