Troubleshooting Roadmaster Even Brake that Sputters at End of Air Tank Filling  

Question:

I have an EvenBrake 9400 and although it is working, it sputters at the end of filling the tank. I figure it will fail eventually and was wondering if this symptom could be caused by a bad Air Cylinder. I have attached a small video showing the issue watch until the end And do you have a video for how to replace this part? Let me know. Thanks!

Hey Rich, typically if the Roadmaster Even Brake Portable Supplemental Braking System # RM-9400 is having a leakage issue it's either the Air Cylinder # RM-452109-10 or the exhaust valve # RM-450601-50, with the exhaust valve usually being the number one culprit.

I recommend checking the exhaust valve with some soapy water and seeing if you get any bubbles. The video you mentioned did not make it through.

Thanks Jameson, I appreciate the quick reply. I will look at the exhaust valve. Is there a way to send the video? It is about 8mb. Thanks Rich
