I just changed the front brake pads on my R6. The old pads were well within serviceable thickness, but I figured with a TD coming up I wanted known good pads. The old pads were Toyos, I have no idea how old they were, but they were really hard/slick feeling compared to the EBC pads I put on. Is this normal? Do brake pads get slick with age or were these probably just always that texture? The new pads stop much better, and don't squeak.
