Hissing sound

[JTPatriot]

Just wondering if anybody else has noticed a hissing sound after applying your brakes. If sitting still and you release the brakes then reapply them do you hear a hissing sound? I have noticed that on mine lately that I can not remember it doing before. It may just be one of those things that I just noticed but wanted to check in and see if others have it.

LOL! No, not that I know of. Checked the build sheet and did not see it listed.

Where I live, we check for snakes. You may have ticked one off........... if it rattles, jump the heck out of there - fast.

But seriously, have you tried with hood open, another person applying brakes while you listen on the outside and try to determine approximate location it's coming from?
In the cab it's hard to know exactly as sounds get transmitted and mixed in with other sounds and it can be decieving as far as where it's coming from.
