Pedal feel is fine. My brake reservoir was down about 2 oz, and I'm wondering where it went. It does not seem to be leaking anywhere visible.

Easy check, pull MC from BB, be careful with the steel lines, shine a flashlight into bottom of booster with mirror, or attempt to turkey baste any fluid out.

If you have some, usually that means a rebuild of the MC, or just replace, check costs. Be sure large O ring is seated properly, (alright, replace it!) bolt back together, start engine, let vacuum build again.

No need to bleed anything. You have not disturbed any fluid pressure, just air.

Using a vacuum evacuation tool, mighty vac, will help determine many ills.
