Wanting to lube the brake pistons next time I service the brakes. Can you recommend what grease I should be using?

thx

When you order the Brembo rebuild kits, they send the grease as part of the kits. The little packages carry the brand name Brembo on one side, and on the other they say Kluber Lubrication, grease for seals assembly (in english and german) and have the number 04.2954.10. It looks like a silicone grease, but I do not know for sure.

You can get kits, if you haven't already sourced them from somewhere, from Paragon Products in Texas - that is where I get mine.

I rebuild my calipers in my 986S race car every year - frankly, they don't need them, but I do it for preventative/piece of mind reasons anyway.

When I rebuild, I do not grease the pistons - only the sealing ring that sits in the seat in the caliper.

I think it is OK to put a thin coat on the piston, but I do not do it because of dust build up. On my car, the boots melt and dust gets all stuck to the piston if it has been greased, so I quit greasing them. No problems at all with no grease on the pistons. (I do change the sealing rings eventhough I re-use the pistons unless they are damaged, which has never been the case - still using the original pistons.)

Hope that helps.
