Sound Comes From Clutch

I have a 2004 model 1.4 hdi sw vehicle. About 1 month before the vehicle, when I pull my foot off the clutch in low gears, it sounds like a vibrating phone sound on the table that lasts for 3-4 seconds. They said the print pad set is interrupted, I changed it, but the sound is still coming. Thanks for your help in advance. & Nbsp;
