Caliper Painting Gone Wrong

So I decided to paint my calipers yesterday. After I reinstalled them I attempted to bleed my brakes. Both the rear brake bleeder valves were frozen shut, so I decided to just bleed the front calipers. After I finished bleeding the system, I tried to test my brakes and they were extremely soft! Any ideas on how to fix this?

You must still have air in the system. Try spraying WD40 and hammering around the bleeder valve and tightening it a little to try and dislodge it. In an extreme case, you might consider putting a torch to it but keep that as a last resort.

Because red paint decreases stopping distances by at least half. True fact.

Well I bled the brakes 3 more times, didn't see any air bubbles coming out. The brake pedal is a little stiffer but still waaayyy to soft. Any other ideas?

You have to bleed the back brakes, no way around it.

I replaced the brake bleeder valve in the back brakes so all of them were bled properly.

You have to bleed back brakes first then front. If they still feel spongy you still have air.

Specifically, back right first, then back left. Start the farthest from the master and work your way towards it.
