Caliper sliders - what grease?
Happy Sunday everyone and thanks in advance.
When replacing the rear calipers on my 2005 D3, what slip/grease should you use on the caliper slider pins?
I have a tube of copper grease, which the local motor factor suggested, but i wonder whether there's something better?

I recently greased all four of mine with some Aeroshell 7. General purpose grease, used for wherever. Not aggressive towards the rubber either.

i use wheel bearing grease as i find that copper grease has a tendency to dry out but only use it on the pins that have no rubber on them
for pins with rubber on the ends i use silicone grease as it stops the rubber swelling up and binding the pins in the carriersplease excuse any grammer/punctuation mistakes,i'm thick,thankyou

Red rubber grease is the best for this job other grease such as copper slip can react with the rubber causing it to swell and degrade.Andrew

We dont use any copper grease in the workshop now. We go between ceramic, rubber and LM greases My D3 Build Thread

I thought that copper grease dries out over time causing drag on the sliders? Hence uneven pad wear. I use rubber grease.Series one 1949 - in bits, chassis is strapped to the ceiling in my garage (beside the canoe)

I've never had issues with rubbers degrading or grease drying but I'll definitely take the advise and make the switch over here.

Any old grease, but defo not copper grease.
Large customer lots of vans, lots of caliper issues which was traced to the van mechs using copper grease on the sliders, stopped using copper grease and the issues went away.
At work we are no longer allowed to use copper grease on the wheel or hub fixings, we have been told it has been shown to cause corrosion!

Remember a guy on another landy site a few years ago started posting 'how to' videos and caused a stir with some of them. I couldn't decide if they were satire or not, in his caliper rebuild video he used lashings of Copper slip as assembly grease on the pistons.
Anti sieze and lubricant are not the same. Copper slip has a large amount of Copper suspended in the grease which turns into a kind of grinding paste when repeatedly moved. It will wear running surfaces out quickly. Red rubber grease is the best stuff for caliper sliders.

Clear silicone grease is the stuff the OEM's use.
Agree about copperslip being misused, we only use it on the wheel hubs, it's very rare to lubricate anything to do with the brakes - most now come with shims plated with a hard metal to allow the pads to slide without attracting the brake dust like grease does.
I've seen some brake pads with adhesive backing that some clown has lathered in copperslip, that's a special kind of stupid, that is.
Consider how much grease is on the brakes of new vehicles - none. There's no reason to deviate from that with modern (i.e. this century) materials.
