Hi guys,
simple one this ... I think.
I want to wire brush the mating surfaces between the disks and the wheels before I replace the wheels. Problem is I need to remove whats left of the old grease before I can get the wire brush to it. Any thoughts on what is best to clean off the old grease without giving me other problems in the future.
I'm probably thinking too much about this...sorry for the stupid question.

Any ideas guys???
I know what you mean Phil but I was getting terrible wheel wobble at speed so wanted to clean up the mating surfaces. Like you said I used an old rag due to lack of other suggestions and lack of guts to use a solvent in case it got somewhere I didn't want it and caused it's very own corrosion spot. I ruined a wire brush which is now loaded with grease but the wheel wobble has gone. I have re-greased the mating surfaces with aluminium grease.

Glad to see you've solved the problem. Being more serious than in my previous note, the main issue with using de greasing type cleaners around the hubs is really to do with the dangers of getting some onto the brakes/discs/brake pipes - which should be avoided.....
In an earlier life, I worked for Ferodo (brake and clutch mfrs) and managed to get hold of some (free -courtesy of work) higher performance pads which I immediately fitted (making the mistake of leaving some cleaner on the discs - I was much younger and more foolish then). I quickly discovered the joy of losing most of my braking on a fast downhill stetch in the middle of the Peak District......
made it through without scars....

If you're putting on new discs the hubs need to be spotless to ensure there is no excessive runout at the disc edge cauced by grit/dirt in between the hub and the disc...as I'm sure you already appreciate. Whenever I do the job I become quite meticulous as brakes aren't something to take chances on....we've all got our stories of heart-stopping moments I guess.
I buy a can of aerosol brake cleaner, which is basically solvent in a can and is designed to degrease and remove brake dust from anything you like, ie it is kind to hydraulic rubber seals if it comes into contact with them and so on. Use a toothbrush/old paintbrushes to work the stuff into everywhere to get it spotless and then use lint free, clean rags to dry it off, or compressed air if you have it.
A smear of copper grease twixt disc and hub (evenly applied...you don't want to cause that runout problem again, eh) will help the two to separate if you ever have to do the job again. Do make sure that when you wack it all together again that the disc and friction pads are totally free of any grease whatsoever. This is VITAL.
One final thought. Watch out for air impact wrenches with brand new discs, as using these can pull a disc out of true and you'll end up with the dreaded wheel wobble. Ummm, all this is based on my experience of replacing about 10 sets of discs and pads....not a great deal I know, but I hate poor brakes and replace them as a matter of course on any secondhand car I buy.
Good Luck!!
And for those of you who are wondering what relevance this has to cleaning the area between the WHEEL and the disc, I apologise. Oops, must be a bit tired. RTFQ chin up!!!! I'll leave the message up in case anyone's doing their discs soon.... soz!
