Title says it all – I've got a Trek Fuel EX 9.8 GX AXS Gen 6 with the electronic shifting and SRAM Code R brakes. The bike is currently in the shop due to horrible braking.
The red cylinders appear to be spare parts for the brake system, but I don't recall seeing anything red when I was bleeding them a few days ago.
The black brackets have me scratching my head as well. Are they "problem solvers" for switching shifters and brake flavors with the AXS shifter?

The second photo are the brake barbs and olives. They are at the ends of the brake lines to form a seal within the calipers/levers. You’ll only see them if you remove the calipers from the lines.
The pieces in the first picture look like adapters to direct mount a shifter onto one of your brake levers.
I don’t have an answer to your question but it’s interesting to hear about the horrible braking.
I just got the same bike last month but haven’t had it on the trails yet due to weather. What I’ve noticed test riding around the neighborhood is that the brakes seem to have a ton of lever travel prior to any actual resistance and braking action. I took it back to the shop and they said “well, that’s how SRAM brakes are.”
I’m going to give it a couple rides to be sure but I have a feeling I’m going to be getting new brakes for it, which is disappointing after spending that much on a bike.
Bought the same bike 2 weeks ago, had a baggie of misc parts too. Was told they’re just spare pieces.
Brakes need a bleed and then you need to bed them in properly. Have to do that on all new bikes/new brakes or they won’t work. I have SRAM brakes on most of my bikes and they work fine. (Couple of level ultimates, couple of reds, old G2 RSC, a DB8)
