Break Sound from front tyres of Ola S1 Pro Gen 2

This sound is coming from the front disk pads and disc brake. I have already installed Break pads, but it’s still coming from the front. It might be from the new pads or it has contained oil in it.
Better to give at EC so that they can resolve
If you need it by your self then follow my steps
1.) Washing brush
2.) cloth
3.) shampoo (or) surf
Shampp combined on top of brush then evenly rub the break rim for 2-5 minutes them it’s done water wash it and wipe it with towel
