Hey guys, I have a 06 g35 coupe sport. I do not have a bbk on my car. Since I bought the car I have alway noticed the respose was not that great. I would have to double pump the break to get it to grip hard. If I just hit the break once and kept my foot on it ,it would feel spongy. While me and my buddy were redoing my motor I changed my pads, rotors and drained all break fluid. When I did the break fluid I mad sure all air was out of the lines.
After all this I still have the issue. I drove in a 03 350z, a 04 g35 and one other 04 g35 and there breaks didn't feel like mine do. I'm not sure where to start at this point. I have been thinking maybe 03,04 they used a different master cylinder or somthing. I don't know. I can't imagin why this would be doing this. Does anyone have any info of ideas that I can try to fix this issue? thank guys!!

What do you mean by drain all the fluid? You let all the fluid drain out and refilled it or you bled it all out?

yea just kept opening the lines till it was all out, then i filled it and bled it. Why you ask about how I did it? does it really make a difference? I'm not being smart I'm just asking. I know things can get taken the wrong way when people are typing back and forth.
