rear brake disc rust?

[ant_wales]

My new rear discs seem to be building up some form of orange rust on the outer rim where the pad doesnt touch and on the very indise rim, is there any product i can get to remove this?

No, just leave it its normal.

as said, it's normal (they'll rust within a very short while of getting wet) but, if you particularly wanted to, you could wire-brush it off and paint the edge of the disc with something like Hammerite. not sure how long the finish might last though

steel rusts, live with it!
