Video Transcript for Roadmaster Tow Bar Braking Systems RM-9100-50 Review
Speaker 1: Today we're going to take a look at the Roadmaster Brakemaster replacement air cylinder. Now, this air cylinder is compatible with Brakemaster supplemental braking systems, part number RM-9060, RM-9100, and RM-9160. All three of those systems we do sell on our website.This air cylinder uses the air pressure from your motor home to depress the tow vehicle's brake pedal. Basically, you connect the air cylinder before towing, and then you disconnect it when you reach your destination. It connects and disconnects from the tow vehicle in under a minute without any tool, adjustments or setting. Basically, this clamp right up here, you attach this to the brake pedal on your vehicle, secure it to the floor right back here with this pin and clip, or to the seat adapter, whichever you use, and then you quick connect your air hose right here, and you're all set to go.
It will apply your brakes when you apply the brakes in your motor home.This part is made in the USA. But that should do it for the review on the Roadmaster Brakemaster replacement air cylinder.

Item includes everything in photo - pedal clamp, air release valve, tubing, and adjustable post with locknuts and locking pin, as well as cylinder. Mine came without a label or serial number - the one it replaced lasted 20 years and still works (with one air release valve replacement 5 years ago).
