sandblasting brake rotors

[dave.williams@chaos.lrk.ar.us (Dave Williams)]

-> Cars that sit over the winter here end up with surface rust on the
-> brake rotors.  Any reason that I should not sandblast the rotors to
-> remove it?

 It's not really necessary.  For a street car, just drive it and the
rust will come off.  For a race car, or a street car with fancy racing
pads, you might hit the rotor with a wire brush to knock off anything
soft or loose, then do a couple of gentle stops.

 BTW, brand new rotors usually come with a protective coating.  Running
them out of the box will gum up some pads; we use alcohol and paper
towels at the track to clean them.
