Has any one installed a air supply line for the Towed Vehicle.

Thanks In advance.

Craig,
  I installed a Roadmaster brake on my toad, 2011 Equinox, which uses the coach air brake. See attached for installation instructions and it explains how to tie into the coach air system.
Good luck,
Rick

Hi Craig.  I use the "Brakemaster" system as well.  I found it very easy to install the air line on the drivers side tag axle brake can.  There was a spare port already on the brake can.  All I had to do was remove the plug and install an air fitting and then route the air line back to the hitch.

I had M & G install brake air supply for the toad.  Just yesterday I was rolling around under the coach and found their hook up.  It was a simple thing to do, as they just removed a fitting out of the brake can going to a rear wheel, and added a new T for the newly added air line to the rear bumper.  That new T with some hose and quick connect mounted on a bracket added to the light connection bracket, took them less than 20 minutes.

I have M & G  on my HHR since 08.  Next week they are going to remove it and I am trading it in on a set to go on the new toad I am purchasing.  They will also install the base plate, light wiring, and break away.  I like their setup as there is nothing to do inside the car.  Good thing I only live about 30 miles from "Athens".  DAN

We have an air line to our Jeep Grand using a closed female air quick disconnect at rear of motorhome and an open male connector on the Jeep.

I connected a new air line from our rear wet tank to a ball-valve in our sewer bay. From ball-valve we connect to a quick disconnect that could be used to fill our tires, and to a 12-volt electric shut-off valve which feeds the rear of our motorhome.

In our Jeep we have an air tank filled with a one-way valve. When our motorhome brakes are applied, a 12-volt valve in our Jeep opens to let air from Jeep tank flow to an air cylinder that pushed Jeep brake pedal. We have a break-away switch on the front of the Jeep, when activated, opens the Jeep's electric valve applying Jeep brakes.

We use black nylon/plastic truck air lines under motorhome, in tow-cable, and in Jeep.

Hi,

I use a 2 way 12 volt air shut off valve at the T were you come off of the brake pod, in case I loose the Toad and loosing air pressure I can just push a button under the dash to close the valve so I can get my air pressure back  (used one of the extra wires under the dash that runs to the trailer hitch)

Thanks  to Everyone for your Great Information, Going to get parts Today for the Install I am sure it will involve several trips to Town.

Got underneath the coach To see what was needed to install air supply line I do not have an extra port on the brake can any suggestions we have a 1997 U295 No Tag axel.

Thank You

You may not have an extra, but you surely have a connection.  On my can they removed the OEM connection fitting, added a "T", and then re-installed the fitting into the new "T".  The new "T" has a line now to the rear bumper.

It is simple beyond belief when I saw what they did.  I will undo it when I upgrade coaches, and do the next one myself.

One point that might be of interest, the guys at M&G told me that if the 1/4" air line used for the toad brake should break it would not affect the braking of the coach. The loss of air is so small that the compressor output can exceed the loss of air out of an open 1/4" air line so there would be no catastrophic result it the new brake line broke.

You would however know very quickly if there was a problem by the drop in air pressure when you turned the coach engine off.

But just in case a broken 1/4" air line looses too much air and affects motorhome brakes, some have installed a solenoid at the Tee that will turn off air to Toad from driver's seat.

For the air line to my toad using the Roadmaster brake cylinder that pushes on the toad brake pedal, I installed a tee at the top of a brake line that feeds one of the rear brake cans.  I think it is better to put the tee there than at the can as the line at that point does not move up and down as it does at the can.  In other words there would be no flexing of the brake line to the toad when installed that way. At least the part of the brake line installed on the coach.  Make sure you use the service brake line and not the line that operates the parking/ emergency brake.

FYI, we approached our air line to our Jeep differently. We figured that modulated air pressure is not real important, so when we activate our Jeep's brake pedal with our air cylinder, the pedal is pushed all the way even if we just slowing down our motorhome. We connect motorhome wet tank to an air tank in the Jeep. An electric 3-way 12-volt valve connects Jeep air tank to Jeep brake cylinder when motorhome brake lights are active.

We also trigger the 3-way valve when tow break-away switch is activated, which gives us break-away protection. Tow brake is never applied when using retarder. We were also more comfortable by not tapping into motorhome air brake line.
