copper-grease

This week I wanted to do a shorter post, and hopefully instead stimulate more discussion via comments.  The topic is ‘copper grease’ - have you ever heard of it, much less do you use it on wheels or brakes?  It’s my experience that this is much a more a European thing than American so I’d love to hear whether this theory is correct or not!

Everyone is probably familiar with the copper washer used when fitting an oil drain plug to the sump.  It’s copper to stop the plug binding to the sump and causing problems when you try to remove it.  The same problem occurs with wheels, especially alloy wheels - with the alloy binding to the steel rotor or hub over time.  If you have ever removed wheel bolts and then found the wheel still solidly attached to the car then you’ve experienced this!

Some enthusiasts use copper grease, aka, copper slip, to prevent this - the copper based grease is thinly painted, or sprayed via aerosol onto the mating surfaces - the back inner face of the rotor and the hub flange (NOT onto the threads of the wheel bolts though, and clearly not onto the rotor braking surface!).  This prevents the alloy bonding and of course hopefully the wheel is much easier to remove in the future.  Another common usage for copper grease is to paint the backs of brake pads to stop squeal although there are several other products for this too.

So do you use copper grease?  Or any other grease when removing and replacing wheels?  Let us know!
