AUII disc replacement?

[OzJavelin]

I've just changed the front discs on my AUII ute - set of new RDA standard rotor and new pads. Drives fine, stops fine, but I've noticed on one of the rotors a dark mark running the outer half of the disc all the way around. I spoke with someone yesterday and they said it was probably the anti-rust "oil" used on the disc. I did spend some time cleaning the disc with thinners before installing them, but obviously I couldn't get in the disc fins and whatnot.

Do I need to worry about this dark patch, or will it just eventually wear off? (I can't seem to rub it off with thinners or anything?)

keep an eye on it. should the braking of the car diminish in quality, i could be a hot spot on the rotor. Dont quote me on this though. Without any pics its hard to give an opinion.

But I recommend just keeping a close eye on it.

Yeah .. I'm a bit worried it could be a hot spot, but it showed up after the first drive (about 5km of 80km/h with slow, progressive stops). I haven't done any hard stopping yet ..

.. also it runs around the whole edge of the rotor (about 1" down, all the way around).

I'll see if I can get photos ..

Just a quick question Rod, did you bed the pads in at all, or just drove on them once fitted?
