Does anyone know what kind of grease Audi uses on their caliper pins? I know I can just get silicone paste grease, but would like to know what they actually use.

VW and Audi do not grease their caliper guide pins at all.

That's interesting. Dry lube?

I don't agree, based on my experience with VAG products. From where do you get this information?

I use ATE brand brake lube on the slider pins and on the lip of piston seal to prevent sticking as I wind back the parking brake adjuster.

If it is the same as BMW then there is no lube at all, dry pins in the rubber sheath. At least on my old BMW per the MM.

That's what I'm wondering now. Doesn't make sense for rubber parts.

Like many of those lubes, it is a little ambiguous whether it is intended to be used on caliper slide pins or not. At least that's the way I read it.

You are always better off following what the maintenance manual for your vehicle says rather than what it may or may not say on a tube of lubricant. I never like working on any vehicle without the FSM for this and other reasons.

What is the design of the pins and boots? My Asian vehicles which specify a pin lubricant in the FSM are the short type that only protect the exposed portion of the pin that extends out from the pad carrier. The portion of the pin that is within the carrier bore is going into a bare metal socket. On the BMW however, it is a full-length boot where it extends the entire length of the carrier bore (but interestingly the exposed portion of the pin has no boot protection). If you did grease this type of pin then the grease would be exposed to the environment unlike the design on my Asian cars. BMW compensates by giving the pins a heavy plating (looks like chrome or nickel) as opposed to the relatively light plating on the other ones.

What does rust on the BMW is the carrier bore hole in contact with the outside of the boot. That tends to compress the diameter of the hole and over time can cause the pins to stick. You need to make sure you pull the boots out of the carrier and clean up the carrier bore so it isn't reduced in diameter because of rust.

The above images are for my old cars, I don't know if it is the same for newer ones.

Yeah, I really need to buy/find a service manual. It's designed kind of like the Asian car boots.

Those are the same type of boots VW/Audi uses, like the BMW ones.

If one purchased Tyrolsport metal guide bushings, they need to be greased annually per their instructions, especially the older ones that don't have a dust seal in the back.

Interesting as my E30 318i had what you classify as "Asian" boots for its calipers...

I need to look at the monster calipers on my 135i...

I have always lubed the brake pins on my VW/Audi cars...green grease works and I confirmed with the manufacturer it is safe with rubber or plastic parts..seems to work just fine.

In the Bentley for my Audi Cabriolet it indicates:

4 - Brake pad carrier with guide pins and protective cap
Replacement part supplied assembled with sufficient grease on guide pins

Install repair kit if protective caps are damaged

Use grease included with kit to grease guide pins

And I have to apologize, I was confused about where the pin boots are on my BMW. I kept saying they are located in the pad carrier, but it is actually in the caliper. After I wrote that I started doubting it and sure enough I had it wrong. The principle is the same however.
