Video Transcript for RoadMaster BrakeMaster Custom Seat Adapter Review

Today we're going to be taking a look at RoadMaster's line of custom seat adapters for the BrakeMaster braking system. You'll want to use our fit guide to determine the appropriate seat adapter for your vehicle.This custom seat adapter provides an anchor point for your BrakeMaster supplemental braking system. The BrakeMaster cylinder extends, pressing your brake pedal, and it needs something else to push against. This provides an anchor point for it to push against. As every vehicle is different, RoadMaster has a complete line of custom-fit brackets to ease the installation of your BrakeMaster system.The included hardware will allow you to easily attach the bracket to the base of your seat. The anchor point here at the center of your bracket is going to give you an attachment point for your BrakeMaster system.

It'll allow it to pivot, to make it easy to get the proper adjustment for your cylinder to your brake pedal. The custom bracket remains hidden, so when not in use you won't even know it's there.Our customer Chuck M. had to say, "The RoadMaster 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. It does not get in the way when not in use.

Again, thanks for providing a great product."And that's a good point, Chuck. Compared on the plate that requires drilling into the floor, these custom adapters don't require you to modify the vehicle, and provide a nice solid anchor point.And that completes our look at RoadMaster's line of custom seat adapters for the BrakeMaster braking system.

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.


Comments
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:

2019 seat mount has square pegs which don't fit into round holes. But it works with the front of the seat up some.

Fits and works just like it should. Was sent the wrong adapter in the original shipment but a quick phone call and tis correct one was sent right away.


Comments
Still works fine. Did discover that if the seat is fully forward that the upright post ran into the bottom of the seat. Had to remove the post to move the seat all the way forward as part of the memory recalibation.

This adapter is required if you are using the Brakemaster system and it's easy to install under the driver's seat. Connecting the Brakemaster to it is a snap.

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.


Comments
I am pleased with the Roadmaster products and have had no problems during the past year.

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

Got the package on time, but the fasteners bag inside the box had broken open. As a result I only received part of the fasteners and must wait for etrailer to send me the balance. Overall I would order again fro etrailer.com as I think the delivery company is probably responsible for the rough treatment of my parcel.

This is working Great!! I would order again and reco to rders to buy this

The kit is a perfect fit and will facilitate setting up my new tow vehicle. I also purchased a fitting so that on my rear tow bar, I could tow 7 and 4 pun trailers. I found etrailer easy to work with, the web site easy to navigate and all of the individuals I spoke with on the phone for additional information were very courteous and helpful.

  • Seat Adapter Recommendation for Roadmaster Brakemaster in a 2016 Jeep Cherokee
    I checked with Roadmaster and the correct seat adapter for using a BrakeMaster in your 2016 Jeep Cherokee Trailhawk is the part # RM-88307. If your Cherokee has 4 wheel drive or the Active Drive II system, to maintain the vehicle's stable steering while being flat towed you will want to install the Mopar accessory kit 68321424AB, available from your Jeep dealer. This kit will prevent the Cherokee's steering from shaking while being flat towed.

  • Recommend Flat Towing Components for 2019 Jeep Cherokee Trailhawk
    I do have an option for you but the Demco Tabless base plate kit # DM9519340 does not have a compatible rock guard at this time. I recommend Roadmaster Crossbar-style base plate kit part # RM-521451-4 with the Roadmaster All Terrain tow bar part # RM-522. You will also need safety cables part # RM-645. For a rock guard you can use Roadmaster Guardian Rock Guard # RM-4000 which mounts on the tow bar or you can use a hitch-mount adjustable mud flap system like Rock Tamers # ERT00108 which...
