Is it normal for disc brakes to start squealing after prolonged use, eg in the middle of descending Ventoux? I've got RS785 with shimano pads and Hope floating rotors.
Prolonged use will heat the rotors and 'glaze' the surface of the (resin) pad. Sand the pad surface to remove the glazed material and it should be fine again. Next time don't drag the brakes as much!
