I have an air leak when you release the parking brake quite audible, set the parking brake it stops.
I found a hobbs air switch leaking out the back when brake is released ( after a bunch of work to get it out ).
Hobbs - B 76577 4 9613 is the part.
NC contact by labels.
This part appears to be adjustable. I can't find any info in the forum other than it's tied to the refrigerator lock, interlocks ON brake released
to lock the fridge.
Question, is that it's only purpose?
What is the opening/operating pressure?
There are a mess of replacement air switches with various pressures.
Just get it from Newell...?
