Question on front end fixes

I am doing some repairs on my 1000 and replaced the front right brake caliper and brake line. I got them on no problem but all the fluid was drained from the master cylinder, and after I filled it with fluid the brakes don’t seem to work at all. The brake pedal has no resistance and hits the firewall when pressing it. I can’t even get the brake light to light up when I press the brake pedal, so it seems like brake fluid isn’t even reaching the switch where the front brake lines connect to the cylinder. Do I need to fill the caliper with brake fluid before connecting the line? Should I bleed the brake from the bottom up? This is my first time doing this job on a RZR, so please let me know anything I should do to get the brakes working properly.

Im also replacing the front right hub and disc. I have new wheel studs that need to be press-fitted in the hub, can this be done at home using a vice? Or do I need a real press?
