• Grazed in what way? It can be contaminated by the oil, sometime sintered take a while to bed in (as in they do howl the first time unlike organic), and rotor may have wear on them even when cleaned.

  • unsure how to describe glazing, they're shiny and smooth looking, you can make out a very rough reflection in the glazed section of them. A little bit like the picture below. I've roughed them up with drywall sanding mesh to get rid of any contaminants etc., but they just glaze over again.
    If the rotors are super worn are they likely to be the cause of it?

    They've been fitted for the best part of a year now, the front brake barely stops the bike, even when I'm squeezing as hard as possible.

  • I once thought my pads were at fault, replaced and same problems. I then checked the rotors with a calliper as they looked fine and they were utterly worn destroyed.

    The upper pad in that picture looks unevenly worn, so possibly the calliper isn’t well aligned.
