discolored brake rotors.

A while back we had a member from the UK who had horribly discolored front brake rotors. We gave all kinds of advise, but I don't know if any of them worked.
This morning I stumbled across this!

Missed this one! Only $38.00+ from the manufacturer!http://www.brushresearch.com/brushes.php?c1=6

Aren't they supposed to be disc-colored?

I hope the intention is to use the tool on rotors off the bike and then thoroughly clean?

You wouldn't want that silicon carbide anywhere near your slave cylinder pistons. A 'flap wheel' in a drill might do a similar job.

As long as the disc/s are not discolored from over heating from overly agessive use or a caliper piston not retracting, this is only a product I might use when replacing the pads.

Want shiny discs?...use cintered brake pads.

Since my first 944 I have done something different...

I bought a black-oxide kit from Eastwood. First clean the rotors really, really good. Some come with a coating of cosmoline oil. If necessary, throw them in the media blast cabinet. BE CAREFUL on rotors that have built-in bearing surfaces, such as early brake rotors for some VWs and audis if you go the media-blast method.

After drying, soak the rotors in the black oxide fluid for a minute or two. Slosh it around a bit to make sure you get it in all the areas of the rotors.

Then rinse off with water. Not for too long. Air-dry the rotors.

Then soak in the sealant for a minute or two.

Rinse again, dry and install. The look is pretty cool. It's almost like bluing on a rifle, if you've ever done it. And it also stops the rest of the rotor from getting nasty surface rust.
