• Sand the rotors a bit and clean with isopropyl before and after sanding, or you'll just transfer shit from rotors to pads to rotors. I find it easiest to do with the wheel on the bike and spin it with sandpaper on the rotor and try not to cut your fingers off.

  • Yeah, I did that and sanded the pads but it started getting noisy again so now I'm going to try sanding+iso the discs but then using new pads.

  • Don't know if its been mentioned, but what combo rotors/callipers are you using? Some mixes are noisier than others. Mixing sram/shimano etc. Can you switch over or borrow some other brand rotors to test?
