2018 Ford escape SEL, did the job but brake fluid was still low. I'm not a mechanic or know anything about cars but I prefer to just YouTube stuff because I'm not able to afford actually mechanic work.

Long story short I changed the caliper, brake, and rotor on my car but afterwards I got the message saying my brake fluid was low after filling the reservoir. I pumped the brakes while in maintenance mode (again I have no idea you weren't supposed to do that if that's the case) and it said that I was still low on brake fluid and when I checked the reservoir yeah there's not a lot of fluid left, however there's no leaks in any of my lines

I was able to get the car out maintenance mode, pumped the brakes and still have the issue

What should I do next?

I tried looking for answers but I guess no one had any
