• Are the pads hanging over the outer edge of your disc? It could just be that your new disc has a slightly wider braking surface than the previous one. I've seen a few shimano setups where the entire pad is being used, but only about 80% of the disc surface.

  • The disc is the same model as before. So... unlikely.

    The pads however have changed. I upgraded to a "better" 2quid more expensive version. I'll check where the disc sits and if it clears the upper edge of the pads.
