"Well, there's your problem..." one might say.

My friend and I opened my brakes and found reason for that crakling noise which I keep hearing from time to time and also we noticed the mother of all brake system problems...
The noise came from the 5mm stone that was stuck between caliber and outer ring of the disc. That small stone was crawling against the rusted disc edge and sometimes when it got stucked real bad, it made just an awful BANG noise when it eventually got free. We took it out and there goes all the weird back noises.
Then while we were dusting and cleaning those calipers, we noticed that there was some uneven wearing (or how do you say that in english...) on sliding area... It has two levels and deeper one was clean and no so weared area was filled with rust and other stuff that was stuck on there during past winter maybe... We both made same conclusion that this prevents the brake pads clear of from disc and when it do happens it might cause a metallic "snap" sound from the brakes...
Also, the pads from that side was oddly shaped, so we decided that I really need new calipers anyway now...
I made some quick query to our local shops and it seems that my only choise for 1.4 Polo actually is VW's OEM parts... Which is too bad, because I really wanted calipers which I can paint white...

eeh... I know.

But it looks nice, because I have white rims also.
Atleast, I think it looks nice.
