Bremszylinderpaste.....i have that too...
But volvo ptfe silicon grease (or any generic silicon grease on your market) would be better than that bremszylinderpaste!
I do "brakejob" on about yearly basis...and I can recall that previous to the silicone grease when I was using that ATE one...whenever I dissasembled brakes (pins) there were none of it on pins after a year....when now there is almost the same amount of silicongrease as I put it in at the last insoection!
