Yeah I meant to mention, when you install new pads you have to pump the brakes afterwards until the pedal is hard to press, this builds the pressure back up for a firm brake feel, was this done.

even if not done it will happen while driving. this happens because you compress the piston all the way in and it needs to come back out alittle. this is not what he is noticeing.

likely what is happening is the pads have not set to the minor grooves in your old currently have less surface area of pad on the rotor. it will set into the rotor soon enough. find a nice quiet road and do a few MEDIUM stops from 30ish mph. but do not get them to hot as this will warp the rotors.
