Today I changed all of the brake pads and flushed the brake system using Motul RBF 600. I had Akebono pads and replaced them with more Akebono pads.

To bleed, I used the pressure method when I would pressurize the reservoir to about 15psi and then crack open the bleeder valves at the calipers and let the fluid come out slowly. I used a turkey baster to remove as much fluid as possible from the reservoir first.

While bleeding, the reservoir never emptied, the lowest it got was about 1/3 full. Fluid was always exiting the bleeder valves. Never saw any air bubbles coming out. I put nearly 1L of fluid through the system until it came out clean on all corners.

When the front right caliper was bleeding under pressure I decided to get in the car and pump the brakes 2-3 times to speed up the process... probably not a great idea. But I figured since the system was under pressure that it would be okay. After doing this I continued bleeding this corner using the pressure method and never saw air come out, so I don't think any got in.

I'm thinking the new pads just aren't as grabby and need some time to break in. I only put a few miles on them so far.

If more miles doesn't help then I will likely try to re-bleed and see if I can use INPA to activate the ABS module to help clear bubbles out of it.

I find that new pads and a bleed often take a little time to fully bed in and will feel soft at first.
If you're sure you didn't introduce air into the system, give it a few days to see of the pedal firms up, if not, I would re-bleed.

Those power bleeders often send air into the system. Air bubbels could be seen into the plastic hose that pushes the fluid. Sevirity depends on the bottle possition. Watch this video. Start at 19 minute mark:

New pads on old rotors? They will need time to bed in. Also air could have been sucked back in caliper when you pumped the brakes
