What’s this in the brake fluid reservoir?

I was looking at fluids before my trip, but it looks like there’s something that doesn’t belong in there. Is this normal?

 

Are you talking about that screen or crossed plastic piece? If so its normal

 

It’s underneath the screen. Looks like little pieces of plastic between the plastic cross part. I don’t want to mess with it since not sure if I could get myself in a hole I wouldn’t be able to get myself out of

 

The screen is torn, and that’s why it looked weird.
What I thought was debris, was a piece of plastic that’s inside the reservoir.

 

Yank that F'er out. You can live without the damaged screen. Just keep crap other than DOT 3/4 brake fluid out of it.
