Video Transcript for Review of Roadmaster Tow Bar Braking Systems - Replacement Breakaway Switch - RM-650898

Hello, everybody. This is Jeff at Today we're going to take a look at the replacement breakaway switch for the Roadmaster supplemental braking systems. This is for a quantity of one switch. Now this will replace the breakaway switch on your Roadmaster supplemental braking system. And basically what the breakaway switch is.

It's a safety requirement. When you're flat towing a vehicle behind your motor home it'll prevent a runaway situation. If the tow vehicle would ever come detached from the motor home. Basically, this switch is wired into your supplemental braking system and it installs to the front of the towed vehicle. And then there'll be a breakaway cable.

Now the breakaway cable is not included. We do sell that separately. If you already have one, you can use that but that cable would attach to this pin and then it installs to the motor home. So what happens is if that car ever becomes detached from the motor home, that cable will be stretched. And it pulls that pin out of the switch which will then activate the brakes on the tow vehicle to stop the runaway situation.

This is designed to work with the BrakeMaster systems, the EvenBrake systems and the InvisiBrake systems. Does include everything shown here. Includes the breakaway switch itself. The mounting bolt and a nice set of detailed instructions that'll describe how this installs and operates. But that should do it for the review on the replacement breakaway switch for the Roadmaster supplemental braking systems..

My experience with etrailer was good from the perspective of the cooperation and pleasantness. However, even though I was clear on the tow bar I had (Blue Ox) and the vehicle I was towing (2005 Dodge Dakota) when the tow package came and the shop I had installing it got to the end of the installation, it was discovered that the wrong pins were sent, i.e. they wouldn't lock in place - too short . At first we couldn't determine what the problem was, so I called etrailer back. Was told those were the correct pins. Finally called Blue Ox directly and the rep immediately told me (after I gave him the PN) that those were the wrong pins. Without me asking he offered and did send two replacement pins free of charge. They worked perfectly.


Works just as advertised

Still mounted and ready for duty if need be

This is a new switch, carefully packaged, and complete. My purchase was easy and delivery was fast. etrailer's order status link was helpful with package tracking. This is the second purchase I have made from etrailer and I will continue to be a loyal customer.

No problems whatsoever.

I had purchased and had installed the Roadmaster Brake Pro system on my '00 Nissan Frontier about 10 years ago. I recently traded that vehicle in for a '12 Frontier, but before I did that, I removed the Brake Pro and tow hitch components. I installed all of these components on my new truck, but found that the orginal breakaway switch no longer worked reliably. Roadmaster doesn't sell repair components directly to consumers, but a web search led me to etrailer. The component that they provided was easy to install as a replacement and works perfectly.


Break away switch works flawlessly, have peace of mind while towing !


What can I say it is a breakaway switch to replace the one I broke. Service was great as usual.

Fine no problems at all.

Bought this as a back-up/replacement to use for my Roadmaster Supplemental Braking System.
It came quickly and was just what I needed.


This replaces my original unit for Even Brake. Old unit mounted under front bumper corroded and shorted causing my brakes to lock up. These should be inspected regularly.


Worked and installed easily per the directions. Wired it up through a flat-4 trailer-type connector, along with power, to the Roadmaster ICX transmitter unit--makes for easy install/removal.


Fast delivery, easy to follow


Michelle was great helping me with my order. She knew exactly what I need to setup my Honda CR-V as a towed vehicle behind my motorhome. She explained all the needed parts and was very polite.

Thanks Michelle


Both orders (breakaway switch and harness) were received on the same day and ahead of the promised delivery dates. Quality product as usual. Thank You Odelia!


The item is exactly as described and was shipped promptly and received in good condition. It was packaged well so that would it would not be damaged during shipment. I would definitely use again


Product I ordered was shipped promptly however a part was missing. The pull ring on this brake away switch so had to improvise.


I have ordered many products from etrailer and their customer service is 12 on a scale of 1 to 10. I ordered my products on the weekend and they were delivered on a Wed. I also later found cheaper prices on a few of the items and submitted the info for the 110% lower price guarantee and received the refund within a few hours. These folks are just plain great!


worked perfect


I ordered this in a rush for an upcoming camping trip. It was delivered promptly and exactly as advertised. As always, etrailer comes through when it counts.


Works perfect and easy to install. Installed along with a whole Roadmaster system.


Order was so easy to place. Delivery was made prior to the delivery date stated. Great job. Very happy.


All products purchased still work as advertised. Great quality products to match the fantastic service and part availability.
