I used to clean my calipers out on my honda all the time in winter and used brake cleaner then regreased them with copper grease.
I was hoping they would be done on my 748s at the yearly service but they ain't been touched apart from fluid change.
I read somewhere that copper grease is bad to use because of it can damage the seals around pistons and it accelerates the corrosion of salt on the alloy calipers?
I have a big tub of graphite grease that is hi-temp and very thick will this be ok to use?
Thanks in advance
