Air Brake Info for 05 Eagle

[Ericbsc]

The most feared words of bus conversion (while were at it) have created a dilemma for me. I cut the front of my 05 off  to stretch it forward and raise the drivers area. I also changed to a model 15 front (while i was at it). I removed the air lines at the front bulkhead where they had connectors. I also put in a new brake pedal. Here is the dilemma. I have everything working, depress brake pull out park engages. Press brake, push park in and you are ready to go. Problem is that I have one extra line at the bulkhead. It goes back to the inversion valve on the rear end, then to the emergency port on the chambers. I have a manual but it doesent seem to be plumbed like the dwg. The emergency port should engage when air falls below 45 psi. Were to hook line?

Eric, do you have the DD-3 brakes or spring brakes on your model 05 let us know I will check on a drawing for you, there is a emergency release valve in the lower passenger side corner behind the bumper and some are mounted between the frame past the wheel well on the passengers side.Paul has a diragram for the dd-3 brakes in the tech part on the Eagles web if that will help

good luck

[Ericbsc]

Yes I do have DD-3's. I do not have a valve anywhere near the bumpers or wheel wel

[luvrbus]

Eric you won't have one with DD-3 but I will check the diagrams for you Tue what model of treadle valve did you use when changing it out   
good luck

Eric, Is your air pressure gauge mechanical or electric? Single or dual needle guage?

It would be a big help to you guys if he told what size line he is looking to connect  a 1/4 for gauges or the 1/2 or 3/8 in for a relay valve of some type more than likey he changed from a E 3 to a E 6 foot valve and missed a supply port              have a great day

[Ericbsc]

Ok. Here is what I have. Threadle has three 3/8 ports and one 1/4 port around sides. Port on bottom is hooked to the 1/2 line from the back of the bus. seems to be the main air supply. The line that is open is a 3/8 line from the t-9 inversion valve( I think that is what it is called) which is mounded on a bracket on the rear end. It goes from there to the emergency port on the chambers. There is also a line into the same valve which goes to the service ports. When I take this one loose and press the pedal, I get air out of it. Therefore it is the air for the reg. brakes. The two do not seem to be connected in the valve, because as I said the other one is not connected to anything up front, and does not blow out and air when I hid the brake. The open line does however have a regulator on it under the front step. This regulator has a wire and seal on it. Hope this helps. I know it was hooked to something before. Also when I went to look at the threadle valve I remembered it was the air throttle I replaced not the brake. This means there was some kind of tee or three way this line was hooked into.

Eric,I believe that line is for the old bi fold doors some of the Trailways Eagles had the door plumbed into the parking valve with a air lock also.Did you widened you 05 to a 102   good luck

[Ericbsc]

I didn't widen it. I probably should have thinking back. That was the one (while were at it) I didn't do. I did raise the front and move it forward, new polished lower siding, new upper siding( which the foam guys screwed up) I am replacing that with t6062.Dual pane windows, new wheels & kuhmo tires, new lights, new bumpers, 3 carrier low pro roof units, I don't even remember the rest. I stripped it to the bare frame. A good learning experiance for the strong back and weak mind!!    I have pic's posted webshots.

This one is not for the doors. That line came from the front tank. This line runs to the emergency port on the brake chambers on the drive axle.

[luvrbus]

Eric, I have virgin model 05 here at the house and looking at it the valve is tied into the tank and routed back to the towing air supply but I will remove the bumper today and follow it out for you and I will check with the guys on the Eagle web that have theirs with no siding and down to frame. good luck

Eric, Nice work.  You are going to have a first class Eagle when done

I think the line that you are talking about is the line that a towtruck would hook up to for your brakes to stay off.  Should go with your tow hook behind the bumper.

[Ericbsc]

Nope. Not there either. On the stock 05 eagle there is one small last step to go up before you are on the passenger floor. Right under that step all of the air lines go back. It is under there.

[luvrbus]

Ok Eric, can you see the line and the valve from the first access cover on the deck I don't want to rip my step out if anyway possible to keep from doing that.    good luck
