Answer
Hi, this sound like there is air still in the system, rebleed the brakes, start with the driver side, pump the beakes 3 or 4 times,you will need some one to help you, on this, after pumping up the brake hold the peadel down, now loosing the bleed valve to let the air out, after the air is out, still hold the peadel down,until the valve is closed, do the same thing at the other wheel.
