Video Transcript for Review of Roadmaster Tow Bar Braking Systems - Replacement Exhaust Valve - RM-450601-50

Hello, everybody. This is Jeff at Today we're gonna take a look at this replacement Quick Exhaust Valve for the Roadmaster BrakeMaster, or the Even Brake Supplemental Braking System. Now, this part here will replace a quick exhaust valve on the Roadmaster Supplemental Braking Systems. Basically, this exhaust valve will install into the end of your air cylinder that is inside of your towed vehicle, and connects to your brake pedal to apply the brakes. Just to show you what we're talking about, if you look at that insert picture, it'll show you that air cylinder.

And at the very bottom, you'll see how this installs into it. This end right here is what'll screw into the air cylinder. On this end right over here, this is where your air pressure line comes. It will install to supply the necessary air pressure to apply the brakes. And on this other side right here is the exhaust valve.

It's an opening to release any excess air pressure that might build up in your system. Now, this is designed to work with the BrakeMaster 9000 models, part number RM-9060, RM-9100, and RM-9160. And it will also work with the Even Brake model, part number RM-9400. All those systems we do sell separate on our website. And this includes one replacement exhaust valve.

But that should do it for the review on the replacement Quick Exhaust Valve for your Roadmaster BrakeMaster, or the Even Brake Supplemental Braking System.

Replaces 1 quick exhaust valve for Roadmaster BrakeMaster or Even Brake supplemental braking systems.


Have not installed this yet but the info provided by etrailer is very detailed and should be pretty easy.As always shipping was very fast. Thanks.


Replacement part for the pneumatic cylinder on the in-car braking system (Brakemaster 9060). Easy to fit, took about 5 minutes.

Still works perfectly, the actual valve is a molded rubber that fits inside the aluminum housing. It had simply pershed over time.


Works like it is supposed to here in Sydney Australia


My 2006 Roadmaster Even Brake had worked flawlessly for us until the current month-long trip we are on. Suddenly it started dumping all of its air whenever we pushed test and failed to move the brake pedal. I called Roadmaster to find if anyone could service this older unit. They said they no longer supported these older models but to their credit Roadmaster did offer a substantial price reduction to trade it for a new model. Pretty good customer service for a product purchased 15 years ago!

Somehow, I was lucky enough to find the etrailer replacement valve on a [online] search and decided to try this low-priced solution first before spending over $[xxx] on a new one. Boy am I glad I did! The valve shipped quickly (less than a week) to a forward stop on our Motorhome trip. I followed the clear instructions in etrailer's video and in about 10 minutes, with rudimentary tools, my even brake was reassembled and functioning like new! Great product, service, and price.


Excellent product! Did look exactly like the original but it fit and works perfectly.
Original piece is on the right it the first picture and installed in the second.
Although I had figured out what was wrong before finding your how to video it confirmed my diagnosis. Wish I had searched first.


After finding the right location to install the valve it was an easy install. AND, it worked perfectly. Won't know for sure just how good until I get my car behind my motor home again in the spring.

Never did get it working right.


Fits well and works well





Haven’t actually used it yet. Will be using it in a couple of days. Excellent customer service, and got it when I needed it and it fits perfectly on my Brakemaster.
I have purchased from in the past. Their customer service and support is top notch.


Quality replacement at a reasonable price. Shipped and received quickly. I recommend e-trailer for anything RV.



Still going strong.


Great fast service and it was exactly the right part. I will gladly give it 5 Stars


Website was useful for diagnosing the Even Brake problem.
The video demonstrating how to install the park was very helpful.
The part arrived within a few days of placing the order.
Overall a very good experience, except for the price. But it was better than paying the manufacturer $500 plus shipping to recondition the entire Even Brake unit.


Items received quickly and was able to install them in about 15 minutes.



The replacement valve continues to perform as designed after a year of use.


Item was delivered ahead of promised date and worked as expected.


Repeat etrailer customer: vast inventory, competitive pricing, easy ordering process, and rapid shipping & handling.... couldn't ask for any better service!


The replacement exhaust valve was exactly what I needed after reviewing the video it was clear what was wrong with my even brake the video also showed the repair which was very easy to follow and do


The part repaired my system. There was loud whooshing sound and the brake would apply. The bladder inside the part had failed. This was a direct fit, easy to install, and has worked perfectly.


Fast delivery, the right part for my tow car brakes. It solved the air leak I had. Thanks


Exact part I needed. Fast service also.


Works well


Right part ordered on 12/26 received on 12/31 how to install part video took all of 30 minutes to repair.


Easy install and so.bed the problem.


Exactly what I needed for a fix.

Dana J.


Unit is still going strong.


Terrible Service...! From the day I ordered to the day it was shipped.
I ordered it online on the 4th of July and it was shipped on the 12th of July.
Then it took another 4 days to arrive...


I have not used it yet but got here very fast as said it would will give more up date when I put it to service


good product, great service and fast shipping! I just hope the back ordered items come in soon.
