Lippert brake assistance, help please!

Thanks a lot everyone! Made it! Backing in with no light was fun but we're all setup. My star wheel has a spring around it. The guy helping me said they were self adjusting brakes. Does the spring wrapped around the star wheel make it self adjusting? This is all new to me. I should've taken pics when they were exposed.

Drove through a ton of rain so looks like pop out is leaking. That'll be my next adventure.

Thanks again! You guys are great!
