Suspension not filling up...??? Tag pressure not going up???

[Pete Masterson]

Just in case you hadn't thought about it, but when was the last time the air-dryer was serviced. The recommended service interval is 2 years* (perhaps a longer interval is OK for an RV) as thedesiccantdoes lose effectiveness over time.

And, as suggested, only a small bit of water can cause problems throughout the system.

Thank You everybody for your suggestions......

A combination of filling the suspension a few times after a short

around the block drive did the trick!!!!!!

However is this a sign of something on its way to a failure???

or... is it simply a sign of older parts that every once in awhile

need a little kick start to get going???

the bird did 'rest' for 6 months since it's last venture....

but she is up and ready to go now...

again thank you all for your suggestions...

Keep in mind that the Front/Rear are brakes, not air bags. Those

should peak around 120psi.

In mine, the sequence is that the brakes air first, to about 75-

90lbs, then the air bags, then the auxiliary items, then the brakes

fill the rest of the way. If yours is the same, it sounds like

something is leaking badly during the air bag fill.
