As various people have pointed out in past posts there was quite a lot of white crumbly oxidation between the disc and wheel casting, particularly on the back wheel.
The new tyres come tomorrow ( Michelin Pilot Street Radials - £115 the pair fitted ) and I am wondering whether I can put copper grease on the wheel / disc mating face to prevent future corrosion, or is this not clever as the disc does get hot.
What do you guys think ?
