its the air chamnber at the brake

The hose is attached to the air chamber can I just pull it out

the air chamber with and without a spring parking brake are
relativly inexpensive, under $100 each. a rubber diaphragm in the
chamber is the wear part.

folks neglect to test the park brake diaphragm and 'parkbrake hold
off lines' for leaks. To Test: Build pressure, chock tires, release
park brake, rebuild pressure (20 seconds) then shut the bus down and
listen for leaks. if the leak down time is quicker than leakdown
with park brake on, you have an issue.

here is a good trouble shooting guide for air brakes

When you replace hoses, many of the ends are reusable. rubber hoses
fail inside and out. whenever application possible, plastic is an
upgrade. Plastic air line is tough stuff.

Remember to block up the frame before poking around under a bus that
is held up by air bags.

It may be a little while. I am caring for my granddaughter today. I will look at mine and see if I can help. I have never looked at mine because I haven't had any problems. Tell me specifically where to look.
Most hoses can be manufactured by NAPA.
Block the bus up before taking air hoses off or it could be a mute point.

I wish I could post a picture of it
the hose to me seems to not be a hose that has allot of pressure as the
hoses are only pushed on to a 3/8" metal tube no clams no nothing
they are on the back of the air chamber and run up over the top of it
and in at another hose
not sure where that goes
the hose in the back of the air chamber seems to be in there pretty
good
I appreciate all the info

I think I know what you are referring to. I don't know what it does but will see if I can find it in my bluebox. Mine has a 90 degree rubber fitting with a metal hose inside running toward the front of the bus on the left side. The right side does not have the metal pipe just the rubber, so I may be missing a part, but have not had any problems. I does not appear to be high pressure and may be some sort of vent or exhaust, don't know. I will see if I can figure it out. The rubber grommet looks manufacturer specific.

Jamie, I looked through my Rockwell International books and cannot find a photo of the air chamber, so I cannot determine what that hose does. Probably and exhaust of some sort and the hose is to prevent water from getting into the chamber(pure speculation). Since my rubber grommet is also rotted I will continue to search because I would like to correct mine also. The books say my brakes are Rockwell International Corporation Cam-Master.
