I have a 2006 Silverado but I just put new break pads and my left caliper won’t stop leaking

 

I thatleak from the hose connection?

 

If you disconnected the brake line doing the work that banjo bolt has a crush washer that needs to be replaced. They're a one time use. Or if you bled the brakes maybe that bleeder screw is not sealing properly anymore. Just judging from where I set the wet in that picture.
