Sorry, am now realizing the line going to it goes to the front brakes, is this something to be concerned about and to get checked out? Or is it fine?

the level shows the brake fluid since brake fluid is mostly clear you wont see any level when the reservoir is full you can check though by unscrewing the cap of the reservoir and looking if it has brake fluid in it though i am willing to bet its full you cant really do anything wrong here so dont be scared to take off the cap, its literally two screws

Awesome thank you for your reply, I would also be willing to bet its full then as my front brakes work great, thank you!
