Hi Obe, I think freezing discs in liquid Nitrogen or Helium although effectivly hardening them (which will make them last longer) may reduce the friction ? Its the wearing of the disc as well as the pad that gives the abrasive pads like DS3000 & Black Hawk incredible (though messy

) stopping power.
Steve tried some on a Honda a while ago and said he felt like the discs were made of glass.
I personally havn't tried it, I know its a popular treatment for many things from gun barrels to trombones on your side of the pond.
BTW Syphon the reservoir almost to the bottom, refill with 5.1, then bleed through.
Best Regards Roland GTT
