Rotors affect brake dust

[smellytofu]

I heard word that the rotors on my Astra can reduce the amount of dust that comes out of (mainly Opel sourced Holdens) stock pads. It's ridiculous that I have to clean the alloys every 3 days to keep it from etching onto the alloys.

Is this true or just a myth?

Btw, this section of the forum is really tops! You'll know whcih brand of rotors I'll buy when I need them next. :)

The nasty dust that eats into alloys is mainly from metal pads. A pad with low metal content will reduce the problem. Also high carbon euro rotors will generate more dust as they wear slighly quicker.
There is a Street pad made by Lucas that is low on dust and they work quite well. Cheap too.
ATAP are the distributors.

I dont know if anyone can help.

But on a number of cars ive seen, the mags have like a clear coat over them, for protection i guess...

Now thats ok, BUT

It looks weird like the paint has been either chipped by road stones or is it brake dust eating into it, is it that strong?

or possibly both?

all the cars ive looked at only run stock pads and are cleaned probally monthly.

Any ideas?

The coating on the wheels is a powder coat. The metal from the dust sits on this powder coat and oxidises ( rusts) and adheres to the coating.
