Front brake pads changed but break peddle makes a wooshy sound ?

It is difficult to say what your problem is and you seem to have replaced the pads as normal, I think what you are saying is that you lose your pedal after pumping it up and suggests air is in your system, I remember on some Vauxhalls that when pushing back the calliper pistons you had to slacken the bleed screw to release the brake fluid or it damaged seals in the master cyl. with problems similar to yours,whether that is your problem it is hard to say but would maybe try and give your system a bleed and see how you get on, good luck.
