Hi FZ1obp,
In your second picture it looks like there is red Locktite (Not sure what number the red Loctite is) on the screws you got out, but I understood that you should never use lock thread compound on any fixings that go into alloy threads, I'm not saying you did it, but it looks like someone did, a little bit of silicon grease or copper-slip is the best bet with steel fixings into alloy. just saying trying to be helpful :thumbup
Mixed metals can (over time) cause a corrosion issue, and copper grease can reduce the impact because the copper corrodes first, but thread locking compound has no impact as it has no metal. The purpose of using silicon grease or copper grease is so you can undo bolts easily (and to reduce corrosion), while thread lock is for when you really, really don't want them coming lose. The bolts holding my brakes in place require threadlock, not grease.
