Any help on locating an existing RV brake on my coach? I have an air line connection at the rear of my coach but unable to figure out the manufacturer and location of this system. I know it here just cant find it.

Should be able to follow a line from your rear axle.

There isn't too many air brake units. This is one,
SMI Brake
Would connect near the rear brakes for connection

It'l probably be SMI , M&G or Roadmaster. Hunt for a tank/compressor.

The ones I have seen are pretty generic just a small air coupling not special
for any particular brake system.

well I sure appreciate all of your help and responses. Again, I can see the air line but since I am in the market for a new system I was thinking about going with SMI Air Force 1. I hope this will make that install that much easier. I am towing a 2020 Chevy Trail Boss and I want to make sure I have done everything I can to protect my Investment!

If you know what a regular air hose coupler looks like, the thing you would use
to couple an air impact wrench to. My Brake Master coupler on the coach
is about half that size. I think other systems use the same coupler, even if
it is different it will be easy to change.

The connection to the air brake line is generic and not specific to the braking system. M&G, Air Force 1 or Blue Ox versions of air brake system will all be able to use your existing connection.


What I post is my 2 cents and nothing more. Please don't read anything into my post that's not there. If you disagree, that's OK.
Can't we all just get along?

You need a modulated air supply and should probably contact the chassis manufacturer for guidance.
