                                    I want to tahnk everyone for great support and tips to solve my air brakes problem1= !

Today I finally figured how to do it and its working great ! tanks are full of air and no leaks!

What I did carefully read all teh responds in alst two days and before start wrenching i made 2 calls to well know truck mechanics out of LA area.
Both of them say to stay away from using any torches on the brake foot cylinders , they said the by heating up the brass you will hit the aluminum treads and they have see them melt, twisted and deform, they never used flame on the the air brake foot cylinder body. That made me thinking since I penetrated with teflon type solvent over night and tried one more time with easy out and read nad story how easy the can break!

I was worry about removing entire unit , but made my mind and did it!

I figured I will have way better angle and more room to work on it.

I used zippties to mark all teh tubes fittings, removed mounting bolts and pulled entire E-7 Style Foot Valve body , is made by Velvac

I than placed in the vice and used power drill with diamond barrel shape bit, started in the center to grind away the brass left overs.
I did that with two sizes of bit and after getting good size holw , still left planty wall of brass with treads on it.
Next i used size bigger than before Easy Outs and small wrench and took some tourqe to loosen but it went loose! haha! victory!

Next I used my new discovered Newell's compresor and pumped all the left over shavings trough out all teh holes of the cylinder.

Put new 90 degree standard style brass fitting . both of the mechanics sugested , they have worked on air brakes sytems for 20 years and said thsi type hose fitting and brass male fitting is far the best most solid and they never see any leaks from it.
Its more permanent fitting but again, if workd whye would I ever care if is push pull or otherwise as long as it works!

In my sytem I had 3 push pull style and the last one faild here and leak out air , I wonder if my air brakes suffer too! We just started to travel so I can tell, but our compressor was kicking in every 30 m inutes , now is way over hrs between the cycles.

You will see in the photos how solide is this angle braqss fitting.

After attching all hoses I started 110v compressor and build up al the air in teh lines, dasport gaouge shows 90psi in parking mode. Mechanic mention to make sure stays 110-130 psi while driving.

My wife came back from the store and was happy to see our brakes fixed.
It was great lesson for me not to mess with any parts whan stying in remote area , but same time I have learned much about the function of the air brake sytem and thet can be fixed.

Thank you all again for taking tim and tips and sugestions, it would be very hard to do anything with out so much input on thsi forum.
