I have various greases at my disposal but wondered which you would choose on caliper slider pins that have a rubber insert.
I've read today ceramic grease should only be used on pad ears and is not really suitable for slider pins which is news to me.
Silicone seems to be favourite.

Silicon grease is usually recommended. I bought some dialectic stuff from amazon for a recent brake upgrade for less than a tenner.

Another vote for Silicone as it is kind to the rubber seals. You can pick it up from Toolstation if (like me) you're midway through a job and realise you haven't got any.
If the previous owners' attempts are anything to go by, copper anti seize will simply turn hard and seize the sliders, so don't use that!

I bought some new sliders and luckily they came with grease but I'm sure I have silicone on the shelf.

Been using molybdenum for years. Good for brakes because it is a high temperature grease.

Mintex Ceratec stuff is really good.

Molybdenum based greases are great for bushes that are in constant motion. They're less suitable for joints that only move intermittently, because they lubricate by plating the bearing surface, and can actually bond the two bearing surfaces together if left static long enough. Caliper pins probably won't be left static for long enough for that to become a problem, but this isn't the sort of joint they're best for.

I've used it for years but just a bit unsure on it's suitability with rubber inserts. Most slider pins I've dealt with are just metal.

I was not aware of that. Every day's a school day! thumbup

Rrg will go hard and sticky way before silicone grease.

Pretty sure red rubber washes off very easily too, its generally used in assembly with rubber o rings, seals etc.
Probably a discussion that will go on forever but i will now use silicone in the future, a white silicone grease was provided with a new slider kit.
Ceratec is probably ok but i did read its not suitable where rubber is present, some sliders have a rubber insert which i think is to dampen vibrations which can swell leading to sticky operation.

Caliper slider grease aka red rubber grease. Same stuff which literally gets packaged with new sliders/rubber boots. Always used it and never had a caliper seize
