I'm trying to clean up calipers cause they're old and rusty. Prime/paint/clear coat them black. Wanted to see if I could speed things up if I use an abrasive wheel attached to a power drill.

Would this attachment >>>
Be too abrasive? Or should I just stick to 2k grit sanding paper? Or what kind of sanding wheels would work best?

 

Get a scotchbrite pad and Simple green, put in some work. 2k sandpaper is too fine, sanding wheel is overkill.

 

or flex hone....

 

I always use steel wire wheel on a drill when I paint calipers

 

oh i missed the caliper part, thought he was just cleaning the rotors... disregard my post... use what i listed to help bed in new pads

 

You over thinking this. The calipers are cast iron. You cannot damage them with sandpaper on a rotary tool.

 

So sanding wheel is the most effective way to go?

 

See post #2.

 

Thanks for all the replies.

 

Just making sure we are talking about the non Brembo steel calipers, big different in what to use between aluminum and steel calipers

 

yes sir, non brembos for DE
