Ed, I always the change the valve in the drivers area the push and pull application valve.the way you can tell if you have a dual system you will have 2 air gauges (front and rear)check your prices they vary a lot and Bendix is not the only manufacture,check midland/haldex and Velac start here http://www.easternmarine.com If you need photos Doyle is here and he has a dual system his Eagle has a good brake system 10" drums on the rear a 6" on the boogie and front with auto slack adjusters on each wheel good luck

Ed, Everything I bought was from eBay, from three different sources. I used the Bendix site as a reference on what I needed, usually the part numbers from them are cross-referenced or they will say what Bendix numbers they match up too.

Clifford, If Doyle is still there tell him I still need that picture (or more) of his air intake system and tall valve covers on the right side. He's got Jakes I am going to add but need to see how they ran his intake air.
I know he said he had to remove his bed to get good shots. Light a little fire under him for me :lol:
Tell him and Coffee the Brenner gang said Hi !!

Guess I have a single air system, two guages but one is main tank pressure (120) the other is brake I guess shows at (90)
30/30 cans from my local parts guy $55? Okay ?
Checking on Qr-1C valve

Thanks ED

Ed, I will tell Doyle you need the photo right now he is trying to rewire where the wiring burnt last year.is the 55.00 for each or both if it is for each thats a little on the high side but if he is local the service may be worth it.

ED, today I took my Eagle to the shop to have the brakes adj and checked, and the right side brake chamber DD3 was bad. It was leaking. The shop foreman said that a new one was around $900. He said if I replaced it with a 3030 it was only $70, well you get the pic. I recommend the 3030, it is not that hard to change (I was helping the mechanic do it.) Of course, they had a pit and that did make it easier. The mechanic also said you can't rebuild the old ones, where the spring is. You can lose your finger very easily trying to do that. One of the mechanics did (he showed me his missing finger). Someone else tried to do it, and the spring blew out and he lost half his face. That's graphic, I know, but it's just not worth taking the chance!!! The new ones are made so you can't get into where the spring is (obviously for safety reasons).
