I recently changed both rear drum brake cylinders and brakes themselves as well as bled the brake lines, but it seems the brake is soft on the first press, but it still is effective i just need to push it in more. A second press is much more firm. Is it possible I need to bleed the brakes again? What could be wrong?
Yes.

Did you adjust the shoes?
Yeah at first they were actually way too lose so I tightened them to be pretty tight so I still feel i can definitely reliably stop it’s just the first press feels soft about half way to the floor, but then feels normal and stops ok.
Is this the most likely issue for this? Thanks for the reply.
Yes.

Bleed the brakes, all of them, front and rear.
If not that, you might suspect the brake master cylinder, and/or the power brake booster (??)
It sounds like you still have air in the system. If there’s an independent mechanic you know and trust, ask him if he has the equipment to pressure bleed the system, and then ask him to do it.
