Hi I would like to ask if it's normal that the pads are doing some noise (not when breaking) when they are cold but after pressing few times the brake it's everything fine. It breaks well even when they are cold but the sound is annoying although it's just heard from the inside.This is the second pair of pads the original were changed just after 15000 miles. I do sometimes press hard on the brakes but not so often. The discs are showing some sign of wear and tear but I read that it's common on modern cars. The car moves freely so the piston on the wheel cylinder is working fine.
