I promise I tried searching for this but there's like a million+ threads and I can't figure out which one is applicable, so apologies in advance if I'm asking a question that's been answered multiple times.
Sitting at an extended red-light, I noticed my secondary air gauge was going down little by little. I would say maybe at the 3 minute mark, it dropped below the threshold and kicked on the compressor. At the next extended red-light, I put the truck in neutral and it maintained 120 psi, but when holding the brakes, it started to leak-down (not rapidly, but enough for it to drop down a bit, as a steady decrease)
After I got home and turned the truck off, I hit (and held) the brakes and heard a slight hiss coming from the air-intake-stack. My question is, I'm not sure if this is all normal and I just happen to notice it being at a red-light for so long, or if this is something to be concerned (minorly or majorly) about.
Also to note, my secondary tank is the better tank that holds pressure 24+ hours. It does not leak (a lot) while sitting, but seems to be only when holding the brakes. I'm thinking it might a dirty check-valve / one-way-valve, but just looking for a place to start troubleshooting if anyone has any ideas. Thanks in advance,
