Instructor Hi there, flat-towers. Today, we're gonna be taking a look at Roadmasters replacement pressure relief valve for the BrakeMaster and the Even Brake systems. We're gonna be showing it off today by replacing it on a damaged Even Brake. Regardless of which system you have the installation is going to be similar. Have you ever set up your Even Brake when you go to flat tow and you hit the test button and it doesn't actually apply the pedal, it just exhausts the air out. That's actually a very common problem on the Even Brake.
We do have replacement parts available here at etrailer so you can fix this. You're not alone at home. This is again, very common. And we're gonna show you how to fix it. The problem is the pressure relief valve located right here.
This is our replacement. It does look a little bit different but it is a direct replacement for that part. And the way that you can check to verify that this is the issue, you do wanna be careful, but if you hook this up and hit the test button like you we're checking out in your car, just do it out here. It normally will exhaust the air just like you saw a minute ago. But if you put your finger over the open hole here you can cover up where the air is exhausting from and it'll actually extend the pedal.
If it does, then you know that the relief valve here is the culprit, it's leaking out of the valve. Your thumb was just a stopper that temporarily made it work. So to get this removed we're gonna remove the two screws that we're located towards the front of the unit there. The ones here in the middle hold our pump and assembly on, these ones should stay with our bottom plate. And then we've got a couple here in the back.
We're gonna use a 5/32 Allen key to remove these. We also went ahead and unscrewed the handle. If you want to take the unit completely off the lid here you'll have to take these C clips off this and then you can slide the arm off here. It actually had the whole thing out but you don't need to take it all the way out. We just need to slide it out enough to access the valve here. So now that we've got access to our valve, for me to remove it, so we'll go ahead and remove the hose, just press it on the outer ring and then that'll just slide out of there And then we can thread off the entire unit. We may need to take the quick release valve out first before unthreading it, 'cause it kind of looks like when we go to unthread this it's gonna hit our cover here when we try to take that out. So we're just gonna go, cause we're gonna have to transfer this over to the new part anyway so we might as well just take it out now. We're just gonna use an adjustable wrench. It's gonna be easiest if you use an adjustable because this piece down here will just work better if you can just use a wrench that you can custom fit to its particular size. In a lot of cases, once you get it started you can unthread it the rest of the way by hand. Now we can unscrew the whole assembly here. And this is pretty similar, once you get it started you can usually take it the rest of the way off by hand. Really gonna put some thread sealant on the threads to make sure we don't have any air leaks. And then we're going to thread the bottom one in down here labeled A, right onto the actuator and then put more sealant on the quick-release end. And then we're gonna thread that in on there as well. We're gonna then just plug our air line back in. I always like to give it a tug to make sure that the quick release did grab and then we can reassemble our unit. Now that we've got our new valve in place and our box back together and reinstalled in the vehicle, we've gone ahead and plugged it all in, it pressurized and now we're gonna go ahead and hit the test button and verify proper operation. And we can see it applies our pedal and it releases, so it looks like everything's working properly. It is gonna do this two to three times. And if everything works successfully the light that was near the test will go green. If it goes red, then you'll need to readjust and set it back into place, as it found an error in its calibration. That's usually has to do with the adjustment in where your seat is. But since we're all green, we're ready to go. And it's also not uncommon for you to hear it to start back up and repressurize itself after the test. And that completes our look at a Roadmasters replacement pressure relief valve for the Even Brake and the BrakeMaster..

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.

Quality replacement at a reasonable price. Shipped and received quickly. I recommend e-trailer for anything RV.
Comments
Still going strong.
Michael - 09/30/2022by: Nick F08/29/2017
Replacement part for the pneumatic cylinder on the in-car braking system (Brakemaster 9060). Easy to fit, took about 5 minutes.
Comments
Still works perfectly, the actual valve is a molded rubber that fits inside the aluminum housing. It had simply pershed over time.
Nick F - 08/29/2018by: Edward 12/21/2020
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.
Comments
Never did get it working right.

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.

Richard - 11/19/2022by: Wayne07/18/2019
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 etrailer.com in the past. Their customer service and support is top notch.
by: Lisa 07/30/2022
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.
by: Timothy 02/28/2023
Item was delivered ahead of promised date and worked as expected.

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.

- How to Install the Replacement Quick Exhaust Valve RM-450601-50I spoke with my contact at Roadmaster about helping you get the part # RM-450601-50 installed properly. Here was their response: Simply orient the Quick Exhaust Valve just like in the pictures, with the acorn top as the inlet and the bottom side port as the out port in to the air cylinder. Also, the reason you can't take the valve apart and replace it with a new diaphragm is because it is purchased with it installed and parts are not available to do so.
