Started removing the valve covers on my 560SL tonight to replace the cam oiler plastic bits and do the chain guides. Ran into a question on the driver's side valve cover. See attached photos. It looks like both the hard line for the brake booster shown in the first photo and the two lines that appear to connect to the AC line (shown in the second photo) have to come off. I suspect that there is no issue with the booster line since my guess is that it is a vacuum line only and will not cause me to have to bleed the brake system. However, what about the two lines connecting to the AC line? What are they and do they have to come off? Will that open up my AC system and cause me to lose all my R12?

Thanks.
