nope all clear, just when applying the brakes!Sounds like tyre rubber on plastic, anything touching the tyre?
If the pads are not wearing evenly check the caliper is moving freely on the slider pins and / or the disc is not pitted on one side.As @Grim Reaper and @T6-Tom says above my outside pads looked fine when i visually check them, however once the wheel was off the inside pads were on the limit, worth checking this sooner rather than later. For some reason they don’t seem to wear evenly
