I have to RR my rear brake valve. I have already ordered the kit and will get that done shortly. It removing the valve, I noticed that the large air line (1 inch I.D) connects to the valve with a 1 inch to 1/2 inch adapter body. I am having a difficult time finding a brake line supplier with an adapter body that large.

Anyone know of a  supplier that carries air line end fittings so large?

Thanks in advance!

Grant, to help me in my air system education, are you speaking of the relay valve? If so, what symptoms what the valve exhibiting? I'm getting a late start in understanding the functions of all components of the air & brake systems - just replaced my rear actuators last week - and would like to know all I can as I go forward looking at everything.

Thanks!

Chuck, the vavle sits just to the left of the passenger side leveling valve. The tag on the vavle says brake valve with a pressure of 85 psi. The valve was leaking around the gasket. In tear down, the gasket was old, dry and cracked.

I am only thinking that this valve supplies the rear brakes. I have not had a chance to look at the repair manual yet. My brakes were working fine. I just wanted to stop the leak down.

Hi;
    You maight also try Motion Industries.  They should
    be in the phone book.  I am replacing the fuel lines
    in the engine compartment and they had the right
    stuff. Look under industrial supply in the phone book.
                             
                                       Good luck,  Merle.
