The other day I had to write up one of the trucks I normally use. Im off the next few days so I didn’t have a chance to see our mechanic. I’m curious as to what happened. As I was driving down the road it kept pissing air and took for forever to “exhale”. Both gauges dropped straight to 150 psi. I looked over the air lines and replaced some frayed rubber gladhand seals. I tried to build air, it went straight to 150 psi and never exhaled.
