Hi, everyone, Steve here with etrailer.com. Today we're looking at this Roadmaster BrakeMaster Custom Seat Adapter Now, folks, this is a custom fit application. Make sure you're double-checking the fit guide here at etrailer.com. Enter things like year, make, and model where it says My Vehicle Information or My Vehicle. Ensure you're getting the right parts the first time. Now, this is made of a heavy-duty steel.
It's been black powder coated on the finish, so it's not gonna rust or corrode on you anytime soon. You're gonna get these two spacers with it, as well, along with the bolts, washers, lock washers, everything you need for installation. This has been contoured to the floor for a tight, customized fit. And it's gonna remain hidden beneath the seat when not in use. Now, this is gonna simplify the installation and also ensure proper positioning of that supplemental braking system in the towed vehicle behind the motor home.
And you literally are gonna be able to go from towing to driving in less than a minute as far as this part of that setup. The brake system can be removed quickly and easily when you have one of these custom seat brackets installed. Well, that's gonna wrap it up for our look together, folks. I'm Steven, thanks for watching.

Tracking was difficult, no notifications. Then to find out there was duties to be paid. I was not impressed.
There is no torque specs on the installation guide. Oh well I will have to figure something out.

I purchased this seat adapter for the RoadMaster air brake system for my 2014 F150. The seat adapter is required for proper positioning of the air brake cylinder. The etrailer web site was helpful in identifying the correct part number and this part was delivered to my home quickly. I have not yet installed the seat adapter but the instructions seem straight forward.

The RM-88291 seat mounting plate for the breakaway system is a must. I do not recommend using the plate that requires drilling into the floor when you can use this adapter and save time. And it does not get in the way when not in use. Again, thanks for providing a great product.

I tried two months ago complaining about the rust on my new system after one year of ownership and I live in a dry climate and I purchased the jacket (which I use) was quickly emailed by Clayton O of etrailer asking for pictures. I sent Clayton O numerous pictures.
I have emailed etrailer Clayton O since then (due to no reply) and he says nothing.
I’ve spent my hard earned money occasionally at etrailer when the need arises. One time I have disappointment, they appear to reach out, then nothing, thanks to Clayton O.

Clayton O. no longer works at etrailer.com. I can help with whatever issue you are having. Unfortunately, rust is a wear and tear issue that is not covered by warranty. Here is a help article with tips to prevent further rust:

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!

Roadmaster was real slow with the delivery of the seat adapter. But Michael kept me informed all the way through to the delivery. etrailer is 5 stars all the way from start to finish. I look forward to using them in my orders to follow.
Now for ROADMASTER products
RM-643 safety cables quality is good work fine Delivery was fast
RM-9160 brake master system Love this system instructions were easy to follow
RM-15267 toad tail light/brake wiring good instructions for install
RM-1550-1 base plate good instructions for install except you need to drill two 1/2'' holes you must measure and mark as there is no pilot hole.
The whole system works great with the 2008 Honda Pilot
RM-88189 seat adapter I have yet to install as I had to make up my own for the trip.
I will say the seat adapter bracket is made just for the Honda and Acura, they had to make custom make. Thanks to all the car towed great for my first trip of 1,100 miles

Fit was perfect when I finally got the right one, the wrong one that was shipped finally got a return authorization after several emails was sent and way to much time to get a return it has been shipped back as of yesterday. Now have to see if they credit my card back for there mistake. If so all is well if not be very careful when you talk to these folks that they get you the right part for the vehicle information you give them.

this is going to be my second car using the roadmaster brakemaster system, it lower cost and i find it work very well, no cutting vacuum line it is simple but does the job, saves about $500. over other setups, also when you decide to sell and need to remove it there is nothing cut under the hood, the set bracket is so easy to install, OK, so when you use it you do have to plug in the airline and pin to brake, take 10sec but i don't have anything to hit my foot on when driving and if you have adjustable pedals this is perfect, works and a much lower cost over other systems

I had great service from Tammy P. when I ordered this complete remote brake kit, including breakaway switch. Shipping arrived as promised and all goods in good condition.
However, when attempting installation of these brackets under 2018 Jeep Wrang Unlimited they kicked up the seat slide release under the seat and I didn't even have the 1" + spacer installed yet. I am currently working with etrailer to confirm/resolve the bracket issue. These folks are very responsive and helpful.

I spoke with Roadmaster regarding the torque spec of that bolt, I'm told it's 53 foot lbs. Hope that helps!
