Took me 3 hours to figure out my swing brake and it was one hose clamp

Had a Liebherr on a site in Fort Worth last Tuesday and the swing brake kept dragging just enough to eat into my rotation speed. I was sure it was a sensor or a pressure issue, spent 2 hours swapping filters and bleeding lines. Then my old foreman walked up, looked at the return hose, and pointed at a loose clamp barely visible behind the cab mount. Snugged it down with a 3/8 ratchet and everything ran perfect. Felt like an idiot but it made me respect the simple stuff before the fancy diagnostics. Anyone else burned a whole morning on a connection that was just loose?
