Can anyone point me to the correct grease for caliper slide pins?
Cheers

I've always used red rubber grease, mainly because the covers are usually rubber and most other greases can react with rubber. I've no idea
whether that is the best choice though.

I normally use copper slip and have never seen any detrimental effects of the rubber, if that's was it is. I did use the silicone grease supplied
with the volvo's new calipers buy can't say I was won over. Just google - silicone brake caliper grease. Just keep it well away from the
pads or they'll be wreaked.

I’ve used CV grease on the basis it is OK with CV boot rubber so will be ok with slider pin rubber

there is a school of thought that says they should be installed 'dry' with no grease whatsoever.
the grease will just hold all the dust and dirt, and turn to a black jam.
I suspect this will work better on loose fitting pins with no rubbers at all.

^^^ I've always used rubber grease - a small tin around £10 by the looks of it now
(i'm still using a tin my dad had that his uncle gave him - its probably a least 10 years older than me and half full still  )

or you could get this stuff - for all you'll need, but they are only a few £ less for a one use size....

the pins that have the rubber boots on defiantly need greased
the other metal on metal contact area's i've tried with and without grease over the years - my current thinking is with a very small amount
of copper grease painted on the contact areas only.
(i.e. just enough to lightly coat the contact surface, but not enough for any build-up / squeeze out if that makes sense)

I used to use copper grease like many folks but a few years ago I read an article that pointed out it wasn’t actually “grease” and was quite hostile
to rubber components. The copper in it can also interfere with ABS sensors apparently so don’t use it when installing sensors. I don’t really use
copper grease anywhere now other than a light smear on glow plug threads when installing.
The article recommended “brake grease” which it turns out is mostly just silicone grease. So I now just use a tiny smear of this stuff.

I use different stuff for brake pad sliding surfaces. It’s Textar Cera Tec which I think I got at ECP

Depends on the slide pins. If they're steel pins in steel holes the copper grease or high temp grease. If the pins have a rubber sleeve on the
pin or go through rubber bushes then red rubber grease. Any mineral grease will cause the fibber to swell and I regularly have to deal with customers
sticking brakes where that's the issue either from DIY or other garages.

I just never seen any deterioration to the seals with copper grease. I actually reused some of them on the volvo when changing the calipers (it was
hit or miss if they were included) and after a bit of a clean in petrol it was pretty much impossible to tell new from old and they were 19 years old.
You can't not put anything on them as they will just bind.
