Proportional Braking

Blue Ox Patriot Proportional Braking

A vast improvement over "on/off," time-delayed braking systems, which brake at a single, pre-set level, the Blue Ox Patriot has a proportional design for precise, responsive braking. The Patriot applies your towed car's brakes with an intensity that matches your RV's braking action. The built-in inertia sensor detects when and how your rig slows down, and it then engages the actuator arm to press your car's brake pedal with an intensity that matches that slowing action. If you slam on the RV's brakes in an emergency situation, your towed car's brakes will respond with the same intensity. If you press the RV's brakes just enough to slow down a bit, your towed car will decelerate in the same way. The result is improved control, better stopping, and less wear on both your vehicle's and RV's brakes.


Easily Switch Between Towed Cars

The beauty of a portable braking system, compared to a unit that installs permanently, is that you can easily switch it between towed vehicles . It's also a great alternative if you own a newer vehicle that you don't feel comfortable modifying. As long as you have a second vehicle breakaway kit (BRK2505 - sold separately), the Patriot can be easily transferred and quickly set up in another car, giving you the freedom to switch up which vehicle comes with you on your next camping trip.


In-Cab Controller with Easy-to-Read Display

Blue Ox Patriot In-Cab Controller

The included controller has an easy-to-read LED display that plugs right into your motorhome's 12V outlet. The monitor slides into the included rubber stand, which can rest anywhere on your dashboard, or it can be mounted with the included hook-and-loop strip.


This unit lets you monitor your braking system while you're driving your motorhome, so you'll always be aware that the Patriot is working and functioning properly. Not only does the controller let you know when the unit is activated, but it will also alert you if the unit inadvertently shifts while you're on the road. This could result in too much pressure being applied to your car's brake pedal, which is why a warning will be sent to the controller so you can pull over and make the necessary adjustments.


As another safety feature, if your towed vehicle ever becomes detached from your motorhome, the screen on the controller will alert you by turning red.


Braking Power Settings

By adjusting the brake sensitivity using the in-cab controller, you can control the force at which your towed vehicle's brakes are applied when the system senses deceleration. The settings range from 1 to 10. The higher the setting, the more force will be applied to your towed vehicle's brakes. For smaller vehicles , you can get by just fine on a lower setting. Larger vehicles , or vehicles with less responsive brakes, will require a higher setting. You can also adjust the force purely to match your personal preference.


The controller also includes a manual override button that automatically activates your towed vehicle's brakes. In addition to serving as a safety measure in an emergency braking situation, the manual override can also help correct sway and fishtailing with your towed vehicle .


Quick and Easy Setup

Blue Ox Patriot Setup

The setup for the Patriot is very straightforward. The braking system will fit nicely on the driver's-side floorboard of your towed car and plug into your 12V accessory outlet for power. To position the unit, first move your seat back as far as it will go and set the system in place.


Blue Ox Patriot Brake Clamp

Then clamp the bracket on the arm securely around your brake pedal and twist the knob to lock it on. If your vehicle's floorboard is uneven, the included feet can be attached to the bottom of the braking system and adjusted to create a level surface for the Patriot to operate. Move the front of the driver's seat forward until it's resting gently against the back of the unit. If there's too much pressure on the back of the unit, the lights will turn blue and red during the setup process, letting you know that the driver's seat should be moved back slightly. The back of the unit is adjustable as well, allowing you to raise or lower the butt pad to fit snugly against the front of the driver's seat.


Once the unit is in place, setup is simple. Push the "power" button, and the unit will begin blinking blue and green lights, signifying that it's ready to be set up. Then push the "setup" button, which will let the unit run through a quick testing process. When the power light turns a solid green, the Patriot is ready to go.

See what our Experts say about this Blue Ox Tow Bar Braking Systems

  • Is Supplemental Braking Really Needed When flat Towing a 2017 Jeep Cherokee
    By law most states now require supplemental braking in the vehicle being flat towed. The easiest system to set up and use is the Blue Ox Patriot # BLU37TR, that applies the vehicle brakes in proportion to how much the tow vehicle is braking. This is the safest way to stop and it reduces wear and tear on both vehicles. Some models of the 2017 Jeep Cherokee may use Mortorq® fasteners. If your vehicle has these types of fasteners, you will need a PFMTS2E bit to remove them which can be ordered...

  • Best Supplemental Braking System for a 2016 Jeep Cherokee Trailhawk
    It sounds like you are looking for a supplemental braking system that will allow the RV to activate the vehicle's brakes while in tow. If this is the case then a brake controller will not work for this purpose. You will instead need to install a supplemental braking system like the Blue Ox Patriot Portable Braking System part # BLU37TR. The Blue Ox Patriot is an excellent option for you that will be very easy to use/setup and will not require heavy modifications to the vehicle like most...

  • Blue Ox Patriot Braking Strength & Sensitivity Adjustments for 2015 Jeep Wrangler
    The Blue Ox Patriot Portable Braking System - Proportional # BLU37TR has adjustable control settings based on your preferences. I've attached an installation video that shows how you can adjust the force of your braking as well as the sensitivity on your remote controller. There is not a specific setting based on vehicle being towed, so I recommend you test out your braking and make adjustments in an empty parking lot.

  • Why Cant Brake Controller Be Used for Flat Towing Vehicle
    The type of braking needed when flat towing a vehicle is different from a brake controller for a trailer. Vehicle brakes are not activated with an electrical circuit and instead are hydraulic pressure. That means a brake controller that uses varying voltage like the Activator cannot be used. The easiest system to set up and use is the Blue Ox Patriot # BLU37TR, that applies the vehicle brakes in proportion to how much the tow vehicle is braking. This is the safest way to stop and it reduces...

  • Does the Blue Ox Patriot Supplemental Braking System Have Breakaway System
    Actually the Blue Ox Patriot # BLU37TR that you referenced comes with a breakaway system and does not require an additional one to be installed/used. I noticed you have a 2013 Honda CR-V. I attached an install video that shows the Patriot being installed in a 2014 CR-V that is similar to yours.

    I have a great solution for you that won't require you to mess with any air lines and will install very easily. The easiest system to set up and use is the Blue Ox Patriot # BLU37TR, that applies the vehicle brakes in proportion to how much the tow vehicle is braking. This is the safest way to stop and it reduces wear and tear on both vehicles. I attached an install video that shows how it would install in a similar vehicle plus a help article on tow bar braking options as well.

  • How Does the Blue Ox Patriot Braking System Now When to Apply Brakes
    The Blue Ox Patriot part # BLU37TR has an inertia sensor built into it so that when it senses you are slowing your tow vehicle down it will apply the correct amount of braking power to towed vehicle. The remote is there to allow you to fine tune the aggressiveness of the braking and/or manually apply the brakes of the towed vehicle if needed, but for normal braking once you get the unit set up you would not need to mess with the remote.

  • Does the Blue Ox Patriot Press Hard Enough to Activate Brakes of Vehicle Turned Off
    The Blue Ox Patriot # BLU37TR operates the brakes of your 2015 Jeep Wrangler Unlimited Sahara just fine. This product applies enough force to the brake pedal that the brakes of your Jeep will apply adequately. The brakes of a vehicle still work when the engine is off, without the vacuum assist feature the brake pedal does get harder but if you press hard enough the brakes will still apply. The Patriot presses hard enough to still apply the brakes. The couple times you can still get the...

  • Would the Blue Ox Patriot Brake System Transmit 45 feet
    I spoke to my contact at Blue Ox and she informed me that 45 feet would not be too far for the Patriot part # BLU37TR to transmit and the fact that the skin of your RV is metal would not be a problem either. I tried to get an exact range that the system has and she said that there isn't an exact figure, but that you should have no problems.

  • Recommended Supplemental Braking System for a Towed Vehicle that is Reliable and Easy to Install
    For ease of install and reliability the Blue Ox Patriot part # BLU37TR is the one I recommend. You should note that the only thing wireless about this system is the signal that gets sent back to the tow vehicle to let you know it's operating and if you want to tweak the gain of the unit. Blue Ox states that you don't have to install the wireless remote if you don't want to and it will still work fine. So basically you wouldn't be leaving the operation of your towed vehicles brakes up to...

    The easiest system to set up and use is the Blue Ox Patriot # BLU37TR, that applies the vehicle brakes in proportion to how much the tow vehicle is braking. You can adjust this to be as sensitive as you need for the braking of your towed vehicle.

This also has a manual override lever on it to allow you to apply braking...

  • Will the Blue Ox Supplemental Braking Kit Fit a 2012 Toyota Tacoma with Axle Disconnect
    The Blue Ox Patriot part # BLU37TR would be a great solution that would install easy and work well on your 2012 Toyota Tacoma. The rear brakes of your truck will still work with the rear axle disconnect engaged so that wouldn't be an issue at all either. Blue Ox tested this unit in your truck and was able to determine that it would work well.

  • Supplemental Braking System Recommendation for a 2008 Jeep Wrangler
    Inexpensive and supplemental braking systems aren't usually two phrases said in the same sentence. The best and most ideal solution is going to be the Blue Ox Patriot part # BLU37TR as it is easy to install/remove and works very well. The Blue Ox Auto Stop is relatively inexpensive but our installers here don't like it at all and have told us they would never recommend them. I attached an install video for the Wrangler for you to check out as well.

  • Recommended Supplemental Braking System Recommendation for Land Rover Discovery II
    The AutoStop braking systems can be used on several vehicles as long as they are using the correct corresponding tow bar. That being said, our installers here are not big fans of the AutoStops at all. I can't recommend them for you as I don't think it will work very well for you. The common complaint is that it's difficult to install and doesn't offer much braking performance. The easiest system to set up and use is the Blue Ox Patriot # BLU37TR, that applies the vehicle brakes in proportion...

  • Supplemental Braking System Recommendation for 2006 Saturn Vue being Flat Towed
    For supplemental braking for a vehicle being flat towed I tend to avoid recommending the Blue Ox AutoStop as our installers don't care for how difficult the install is or the braking performance. The easiest system to set up and use is the Blue Ox Patriot # BLU37TR, that applies the vehicle brakes in proportion to how much the tow vehicle is braking. This is the safest way to stop and it reduces wear and tear on both vehicles.

  • Supplemental Braking System Recommendation for Flat Towing in Mountains
    For supplemental braking in the mountains I would not recommend the Blue Ox AutoStop. Our installers don't like the braking performance of these kits and they are pretty difficult to install. Because of that I would not feel good recommending them for you especially since you'll be in the mountains where braking is incredibly important for safety. The easiest system to set up and use is the Blue Ox Patriot, # BLU37TR, that applies the vehicle brakes in proportion to how much the tow vehicle...

  • How Is The Blue Ox Patriot Braking System Activated From The Motorhome?
    The Blue Ox Patriot Portable Braking System - Proportional # BLU37TR includes an in-coach RF controller that plugs into a 12V outlet in the cab of the motorhome. This unit allows you to have the manual braking override of other brake controllers, and also allows you to capture any trouble codes. This unit has internal sensors similar to an accelerometer that senses the braking action of the motorhome and sends a signal to the brake system in the towed vehicle. Since it is a proportional...

  • Can Blue Ox AutoStop Supplemental Braking System be Used with Excali-Bar Tow Bar
    The Blue Ox AutoStop Supplemental Braking System # BX8893 referenced in your question is designed for use only with the Blue Ox Alpha or Aladdin motor-home mounted tow bars. You will not be able to use this system with your Excali-Bar Tow Bar. For a braking system, I instead recommend looking at the Blue Ox Patriot # BLU37TR. This is a very nice proportional system that will activate the brakes on your towed vehicle at the same time and with the same intensity that you apply to them in...

  • Why Does Blue Ox Patriot Braking System have Gain Knob On Remote
    The gain knob of the Blue Ox Patriot # BLU37TR allows you to basically dial in how aggressive/sensitive you want the accelerometer to be. If you dial it in with high gain the unit will apply the brakes harder when detecting braking, lower and it will be a softer application. The bumps in the road are basically moving the Patriot quick enough that it basically is thinking that you are applying the brakes. In the mountains the system should still work great. You would want to keep the remote...

  • Can Brake Controller be Used as Supplemental Braking for a Vehicle Being Flat Towed
    Trailer brake controllers cannot work as supplemental braking to apply the brakes of a vehicle being flat towed. You'll have to go with an actual supplemental braking unit.

This is the safest way to stop and it reduces wear and tear on both vehicles.

  • Where to Mount Breakaway Switch of Blue Ox Patriot Braking System on 2017 Jeep Cherokee Trailhawk
    Here is what Blue Ox lists for mounting the breakaway switch of the Patriot part # BLU37TR that you referenced: With the pin facing the motor home, secure the breakaway switch onto the front of the towed vehicle in a sturdy location. This should be a convenient location which can be easily reached, and if possible, on the driver side. Note: The breakaway switch must be mounted directly on the towed vehicle and not to be installed on the tow bar or bracket. The surface must be strong enough...
