you should flush all the brakes on all four corners. Add fluid BEFORE it runs out on the reservoir. Keep flushing and adding till you see all clear fluid coming out. Good luck dude.
Yea, the problem is that I did them on Sunday.... and didn't do that. So Its all new fluid but I'm not sure if its just the lines flexing/ actually rear brakes are working/ or bubble in the line. I did from front left, rear right, front right rear left. then had a helper at the end to do the pump pump hold thing. I shoudl see if I can get a buddy to help me out this weekend and just go through like a cup of fluid on each corner to make sure its all out. The brakes are prett solid near the bottom but it still feels like I can bottom the pedal out.
