    Hi, can some Audi tech or someone in the know tell me if grease G052 150 A2 is the correct grease for the caliper slide pins. Audi will only sell me the repair kit for each side and won't tell me what the actual grease is. Can anyone help?

    Looks like there are 2 options....either G000650 (Solid Lubricating Paste) or the one you mentioned, G052150A2 (Lithium Lubricating Grease)



    I can have a look on ElsaWin when I get home tonight to see which one should be used for what purposes.....however, for the price ($40 - $50 from what I have seen, can't find UK prices), I would rather get a tub of 3M Clear Silicon Paste for the caliper slider pins!

    I wanted to stick with the genuine stuff and already have a supply of this grease. Just wanted to confirm.

    Terrible idea! If the grease used in the copper grease is petroleum based it will destroy the rubber boots that the slider pins go through. Silicon paste works well and is totally safe. Also, I have looked on ElsaWin and there is no mention of using any grease on the guide pins. They do mention the part number mentioned by the OP, but only for lubricating the piston & piston seals when rebuilding the calipers. That's all.

    I've always used LM grease as it's capable of taking the high temperatures the brakes can generate, and over the last 20 years I've never had a problem with damage or perishing of the rubber boots. I would use a little bit of grease as water can get in and cause the pin's to seize with corrosion, and smear of grease on the pin will help stop that. Castrol LM Grease

    I still wouldn't use copper grease. When the grease gets washed out over time the copper remaining can gall up the inserts for the slider pins and make things worse than if nothing is there. The LM grease mentioned above won't do that.

    Also, if the LM grease isn't damaging the rubber then it has to be a synthetic rubber, but without knowing for a fact before hand I would have still avoided the use of petroleum based grease as they can and will destroy natural rubber. Hence I keep suggesting silicon. It won't gall up the inserts and is 100% safe on all kinds of rubber. Not to mention...have you ever tried getting silicon off your hands...water does nothing to it! So it can't be washed out easily either.

    ever tried washing copper grease off your hands. ??
    i also have been using it for years as i find it works better than anything else at keeping those little old slider pins sliding. if water is getting in though, it needs a new seal.

    Copper grease. On everything! Many brake pad kits come with a little sachet of it.
