Airk Brakes won't pressure up

[bluebirdfitz]

I went out this morning and started the coach, and the air pressure
went steadily up to 150--same as happened last year. I've been
driving the coach all day, and she seems to be running fine. Thanks
for all of the help; I certainly know a lot more about air brakes than
I did a day ago. This is a great forum.

Thanks again,
