Left over parts on a new build...what are these?
These are two parts that came with my bike for a new build that I have no idea what it belongs to. Can anyone tell me what either of these two things are?
The pin has a hole through the center of it also. I am assuming this fell out of my Shimano SLX brakes or it just came with the new frame in general, but I can't think of what it is used for. My brakes came pre-bled and ready to go and I am not sure if they fell out of the box on arrival with that as spare for something, or something else entirely different. It was one of those I looked down on the floor and saw it there and no idea where it came from.
Thanks

The part on the far left appears to be a unit of currency, equivalent to 1/4 of an American Dollar.

Reminds me of the movie "Doc Hollywood".

Brass part looks to be part of a hydo brake olive. The other looks to be a pin that holds the brakes pads in place.

So, I think the brass part is the compression coupling, and goes on the outside of the tube.
The hollow screw thingy would go on the inside of the tube, also part of the compression joint. It appears to have hose barbs as part of it.
It could be that Shimano sent you extra parts, in case you would need to cut a hose shorter, you have all the parts to cut and reattach. Or, if a hose gets damaged.

The are an "Olive and Connector Insert" for the end of a hydraulic brake hose.
The olive slips over the brake hose and the insert is pushed into the end of the brake hose. The olive, hose and insert are compressed when the fitting is tightened, preventing hydraulic fluid from leaking past the end of the hose.
See item number 2 at https://si.shimano.com/pdfs/ev/EV-BR-RS805-3852C.pdf. Be aware that there are different part numbers for different brake and hose models but the one in the PDF is similar to what is pictured and function is the same.
The insert shown above is a little chewed up from me trying to remove it with pliers. The barbs dig into the inside of the hose and they don't come out.
I'm going to question @Bike Jedi as to why the part is left over. If you built the bike yourself and didn't install it then you need to take it apart and do so. If the LBS didn't install it then shame on them. Either way, you will know pretty quickly why they are needed when you try to stop, the brakes don't work and fluid leaks everywhere. Give the levers a hard squeeze before you ride.

Pre-bled brakes generally need to have the hose shortened to fit whatever frame you put them on. Shimano includes an extra hose barb and compression ring, so you can cut the hose to the proper length. If they happened to be the right length, just keep the parts in case you need them later.

I know, right? Lately, I've been keeping an eye out at the thrift stores for an ideal plastic container (Rubbermaid, Tupperware, something like that), to consolidate at least some of the smaller spare parts. I've got them scattered around in old bike stem boxes, shoe boxes, a junk drawer, a shelf on my bike rack, the garage work area, etc.

Thank you. That's what I was after. I was using the other parts as reference for that thing. Hopefully nobody comes in and derails the thread trying to label the parts when I was after what that shiny thing on the left is. Thanks for clearing it up!

I sincerely doubt I get the smart cutie in the end. But then again, I did love that movie as a kid.
Perhaps subconsciously, I am always hoping to be Doc Hollywood. I know that I am always looking for that perfect little town. Doesn't seem to be real at all though. Life is quite the disappointment. Maybe a bike trip around the world will cheer me up.

I did build literally everything "but" the brakes. They came cocked and loaded from the bike shop. Had a tough time not having experience with the front adapter and the weird mounting, but a week later and two different mounts, the front brakes were mounted successfully yesterday. I thought that was probably what that ring was for, and it might just be an extra. I sincerely doubt the shop forgot to put that into the build. It was in a package with 2 bolts that looked like they go to a brake adapter, so it makes sense. I don't have a wheel set to throw up on the bike yet so I don't want to test them without rotors in there. I feel pretty confident the shop did them correctly, but nothing surprises me today.
OK...so that's what they are. It has to be extra's. That's pretty cool the LBS included them as extra's in shipping. They really went the extra mile! I bought XLS brakes, with the intent to change the cotter pin in the caliber to the screw in the XT, and you have the same exact caliber and brakes as the XT, minus an adjustment screw up by the lever. I stuck with U.S. supplier who wasn't the cheapest dealer on Ebay because I wanted faster shipping and it paid off. The folks at the bike shop actually changed the cotter pin and pre-installed them without advertising they were doing that. Those screws are like $12 bucks extra and I thought it was really cool that they installed them for you and don't even tell you. If folks don't know that trick, they are actually upgrading them for them to the XT caliber and not even advertising this fact. That makes a very cool bike shop!

Thanks for enlightening me on the matter. Have a great night!

I just picked one up from Harbor Freight for the really small stuff. 24 small clear boxes with snap lids that store into a larger box.
I was going to post a link to it but their web site appears to be down right now.
I believe it was $4.99
