Can’t bleed brakes

Forgot to update, but the new master cylinder fixed the issue entirely. Didn't even have to bleed the ABS.

Glad you figured it out. I was going to take a stab at it and say (because I've seen this before) make sure your bleeder is at the top og the caliper. I've seen RH and LH calipers mixed up before.
