2004 Toyota 4runner brake issue

Hi everyone! So I have a 2004 4runner SR5 4wd. I switched my oem rotors and pads all around to Centric rotors and Akebono ASP pads. As soon as I swapped them and took it off the lift and turned the car on, the pedal felt like it had no bite. I had the system flushed, tried using tech stream to reblead entire system. I am kind of lost of why the brakes just don't feel touchy like they did before changing and why it takes a lot more pedal movement to have to brake. There is no leaks in the system. I have a really hard time believing the master cylinder went bad because it was find literally prior to swapping the rotors and pads. Could one of my calipers piston be stuck? Anyone have any experience with aftermarket pads and rotors for 4runners? My new brake setup has around 3k miles on it, rotor still looks brand new with the new lines on it. Should I do a 60-10 mph hard braking break in like 10-20 times? This car gets driven on highway for 65 miles round trip and the brakes feel scary to have to press the pedal so low.
