Chris & I discussed ::) the use of copper grease on cliper slides a little while back. ;) ;D ;D ;D :y

Personally, I coat the sliders with engine oil - though obviously only a small amount.
Never had any problems with this method.

I am sure read somewhere that it was wise to use a silicone grease,but as never stripped and rebuilt calipers before wanted to use correct stuff...when I pulled old bolts out it felt like a very thick grease so don,t think engine oil would be appropriate.

you need a non mineral based(so it doesnt eat the rubber) hi temp(so it doesnt melt) grease(so it lubricates). Usually silicon based often red for some reason. To mark it out as not normal grease i think.
Do not use copper slip, it is not, i repeat NOT, definately 100% NOT a lubricant. Especially not for brake sliders.
Would have thought Andy would have told you that. :-) (snigger)

Just out of interest when I went into local dealers today,I asked the workshop foreman what they used and what was the recommended slider bolt lubricant from Vauxhall.
He stated that they always use "copper slip grease" so I am now puzzled.
I totally understand the logic put forward by Chris which I tend to agree with over that of the dealer...but what should be ussed then ??some say engine oil/copperslip/and now some "red stuff"..Help

The caliper pistons come into contact with the brake fluid so the grease needs to be compatible with both brake fluid & the seals. I use red rubber grease, little sachets come with the seals if you buy a refurb kit but you can buy a tub of it quite cheaply. Alternatively just use brake fluid, if you have switched to silicone brake fluid use that.
The caliper sliders don't come into contact with brake fluid but they do get hot so copper grease is is good.
PS Copaslip (spelling?) is a trade name for copper grease.

copper grease is what i use, apply a thin smear to the back of the pads(stops squeel), the bit where pad meets caliper a tiny bit(you dont want it on the pad or disk). in the caliper sliders i use it, although if your not a racing driver any high temp grease should do. never had a problem, even after six years. so if it does like rubber it only does it very slowly!
