I’m worried cause this looks like E-brake hardware. I don’t think it came out my tools and stuff. I’m thinking maybe I pushed the caliper into something when I put it on, but this never happened before. Also I’m thinking maybe weak parts from rust. Right now I don’t know because my fluid is empty and why I assume and hope my park light is on. So I haven’t drove it yet after putting this new caliper on.

Can you identify these parts please and tell me if I’m safe to drive… Thank You
