Noises when brake d max

I have a problem when you step on the brake pedal, there is a chillido on the front wheels, I have already changed the brake pads, I have cleaned the discs. The chillido appears when some km has already been traveled and only when the pedal tread softly. If someone has the same problem and I solve it, I could tell me what I have to do to correct the problem. Thank you.

Friend If the pills are alternative it is unclear that you take away the noise, it is not any mechanical problem is only that the pills are very hard, or it contains many lumps of different components, it will be removed alone and then it appears like this it is and it is not much that you can do unless you put original pills that are softer, luck

Hello friend, it is as the Kikemec colleague says, change the pills for the originals and rectify the records, greetings.
