hermanmullins Report post Posted May 24, 2017 Good point Joe. Has anyone tried to stop a vehicle with power brakes from rolling when the engine is off. You almost have to stand on the brake pedal with both feet. Not being that familiar with the AF1, but I do know the M&G. When the bake on the coach is applied the same proportional pressure is applied to the Master Cylinder. It did no have to go through the Power Brake Booster to apply pressure to the Master Cylinder. Many brake system that connects to the brake pedal only satisfies one thing, "It only shows that you have a brake on your tow if ever questioned". I am sorry, any braking system that must be lifted from the trunk put in place, then adjusted and that it might run down your battery and become useless is just my idea of a good system. Sorry, Herman Share this post Link to post Share on other sites
wayne77590 Report post Posted May 25, 2017 I use AF1 and first was installed on Saturn Vue, then purchased Lincoln MKX and transferred the AF1 to the Lincoln. After 65,000 miles it is still working. Share this post Link to post Share on other sites

Sorry, Herman Yes, that was a concern of mine Herman, power brakes pretty much need the motor running to perform properly. Even though when I questioned Roadmaster about it they assured me it was fully proportional and it would apply the brakes as normal. I see now they were not being very honest with me so Roadmaster has not gained any friends in this camp. I did speak with Monty and will be going with the M&G system. I'm also counting on Roadmaster returning my money for their UNOPENED Brakemaster kit. We'll see how that goes. Share this post Link to post Share on other sites
PARRISHNM Report post Posted June 4, 2017 I have over 100,000 miles on the Roadmaster Air System and have never had a problem. I never needed to pump the brakes. We test the operation before we leave of all lights and the brake system but pumping isn't necessary. The cylinder works perfect every time unless the air hose didn't lock on the receiver.

Interesting that on page 4 of your owners manuel it says. Always release the stored vacuum in the towed vehicle’s power brake system before towing — pump the brake pedal several times. Depending on the make and model of the towed vehicle, it may be necessary to pump the brake pedal repeatedly to release the vacuum. If the vacuum is not released, the supplemental braking system will apply excessive braking force when it is activated, which will cause severe tire and/ or brake system damage to the towed vehicle.

manholt Report post Posted June 4, 2017 Yep, and that's why I don't use anything but AF-1 or M&G ! I prefer M&G because they are in Athens Texas and 3 hours from Galveston & 2 hours from the Ranch! Share this post Link to post Share on other sites
jleamont Report post Posted June 4, 2017 what is the "Roadmaster Air System"? Sounds different from the OP's Roadmasters "Brake master" system. I believe they only make the Brakemaster (OP's original question) and the "Even Brake" system. Even brake is fully proportional, but you have to deal with an air cylinder on the floor, taking it in and out. My friend has one of them. Share this post Link to post Share on other sites

Bill By the time you check the brake lights you have bled the the small amount of vacuum in the chamber and everything is ok. Share this post Link to post Share on other sites
fagnaml Report post Posted June 6, 2017 For my Jeep Wrangler I have the Roadmaster Sterling All Terrain tow bar and the Roadmaster Invisibrake supplemental brake system. My "refinery operations manager" experience didn't like the idea of tapping into my motorhome's air system for the M&G and AF-1 systems and have more connections where an air leak could occur. During the two years I've had the Invisibrake system it has worked flawlessly. Here's a link to info about the Invisibrake system --> http://roadmasterinc.com/products/braking/invisibrake/index.html Nice to converse with a fellow Damon Astoria owner!!

If you hook your air correctly you do not effect the stock air brake system. There is an air relay valve and a pressure tank which is totally independent of the rear air brake system. With this system if the brake air line going to the toad is severed it has no effect on the coach braking system. The air pressure going to the toad is fully proportional.

rossboyer Report post Posted June 19, 2017 I have an Equinox and would have that problem if I didn't pull one fuse. Later I replaced it with a switch. You can also fix the problem by adding a charge line from the coach to the towed battery. Share this post Link to post Share on other sites
bsjones11 Report post Posted August 6, 2019 Ok, so now that I am really confused help me out. I have been using a brake buddy for years. I recently purchased a 2019 Newmar and have a new tow car. The tow car is a 2015 Escape. I have the new roadmaster tow bar set up on the old Edge and will be moving it to the Escape. Many have been talking about the air force one so I started looking at them online. Now I see just as many if not more commenting on the roadmaster invisibrake system. It seems that just as many like the roadmaster as the air force one. One thing I do want is to have the ability to charge the battery while towing. Had a problem without having that before. How about some help?? Share this post Link to post Share on other sites
jleamont Report post Posted August 6, 2019 bsjones11, have you called M&G? Most systems require the charge wire to the car due to their design that is drawing power from the car. M&G doesn’t do that, it’s a simple system that is most cost effective than anything else I’ve seen. https://m-gengineering.com/compatibility-list/ Share this post Link to post Share on other sites
rossboyer Report post Posted August 7, 2019 I have removed the Air Force One from my 2011 Equinox and installed it on my new 2019 Equinox. The 2019 requires a charge line. The 2011 didn’t. I have towed the 2019 about 1,500 miles without any problems. Wiring the light system takes longer to install than the Air Force One. Share this post Link to post Share on other sites
fagnaml Report post Posted August 8, 2019 bsjones1 -- Three years ago I had the Roadmaster Invisibrake installed in my Jeep Wrangler as "process engineer" in me wasn't comfortable adding another connection to the motorhome air system that some other braking systems require. The Invisibrake system, which does provide a trickle charge to the tow vehicle battery, thus far was worked flawlessly. Share this post Link to post Share on other sites

jon48 Report post Posted January 5, 2020 I have a Tiffin DP w/ air brakes. I'm looking to buy a used Jeep Wrangler and it is already outfitted with a Roadmaster Sterling tow system & Invisibrake vehicle brake system. It is not clear to me if the Invisibrake will work w/ air brakes & what if I am using the exhaust brake? The Roadmaster web site has a lot of info on brake boosters and that does not sound like air brakes to me. I was leaning to the M&G system but since the Wrangler has the Invisibrake installed already I am wondering if it will work ok. Share this post Link to post Share on other sites
