I've noticed my brake pedal seems to be soft initially then the second press its normal pressure. I figured I had air in the lines. I bleed the lines starting on passenger rear, driver rear, passenger front, and finally driver front. Took it for a drive, and same thing. Initial press it is softer than the second. So I figured I didn't bleed the lines good enough. So I did it again with same results. I don't have any lines leaking and master cylinder seems leak free. Now when I say the initial press is soft, the vehicle still breaks fine. But there is a definite hard pedal feel on the second press. Then after a few moments (10 seconds or so) without pressing pedal then the pedal goes back to its softer press. Anyone have any ideas? What I did was open the brake blender valve after hooking plastic hose up to it pitch upward to trap brake fluid on valve and air would rise up. Then pressed brake pedal 4-5 times. Looked and hose had filled with brake fluid and then I tightened bleeder valve. Then checked and refilled master cylinder. I did this process over for the other three brakes.
