Perfect fit and just in time for our trip!

by: Pat M 06/13/2020 One Year Later

These were exactly the parts we needed! We tried to find them everywhere and this is the only place we could find. They gave us quick service and we were so glad to have our pneumatic brake fully functional again.

Fantastic!

by: Richard 07/23/2023

great to make a new line so you can make it to the size you need, these do the trick, the roadmaster brakemaster is simple, yes you have to connect each time you hook up, but by design less chance of a failure and NO vacuum lines to cut, this system is a winner.. i have own this and AF1 set up, i much prefer this, once i discount nothing for my toes to hit it out of the way and a more solid connect with less chance of a failure when using by design.. the big pro is very simple to install and if you have multi of toad the second kit is much cheaper to do.

The product is great as is all Roadmaster products.

However, the shipping cost and time to deliver is terrible. The item was shipped on 12/1/2015 and arrived on 12/11/2015. For the price I paid for shipping they could have shipped the product via USPS Priority Mail and it would have been here in 2-4 days!

The need to review their shipping policies!

This worked great!! Just placed a Roadmaster Brakemaster on my 2017 Ford Edge and need to make a small extension to protrude out of my bumper. Worked like a charm. Wanted to hook connectors in this kit straight together but had to use a small amount of hose. Now I can safely and quickly tow my car behind my RV.

by: Jerry 09/16/2021

It was exactly what I needed and expected. It was shipped in a timely manner. I also bought a brakemaster air brake kit from etrailer. I have been well pleased with doing business with you folks, and look forward to doing more.

Additional Air Line Needed for the Roadmaster Brakemaster Braking System
The air line assembly for the Roadmaster BrakeMaster, # RM-921004, is 76 inches long. This cord is only 12 inches shorter than the 88 inch cord # RM-921004-88. I spoke with my contact at Roadmaster and he told me that these are the only two preassembled lengths that they offer.
