Nope! Don’t in BMW.I'm on the fence about lube on the guide pins. BMW says to not use any because it attracts dirt. I have used a small amount of Sil-Glyde and none at all and did not find it to make any difference.
Battle of silicone greases for caliper slide pins
- Thread starter NattyBoh
- Start date
I don't have a handy time machine and the Bimmer is gone.
The factory stuff goes bad in no time, silicone grease appears not to. I was fortunate to get 2 years without sticking caliper pins on a NEW car. Once the grease was replaced with silicone grease and the damaged parts replaced, I wouldn't need to touch them anymore. I could fill half my workweek redoing brakes when I first started.

Thanks for the recommendation - just ordered some for my next brake maintenance. I ran out of my Permatex stuff.
Mission, i like it better now than sil glyde. I had some sil-glyde get gummy with age.
Well, this seems appropriate:

Sil-Glyde for me. Use it on the pad backing, ears and pins. It lasts and works well. The only time I use something different is if the pads come with something because then I feel bad for not using what is provided.
Speaking of PTFE I've been using this CRC brake lube for years with no issues.
I've used the Raybestos DBL-2T for 20+ years on pins and slide rails, never had a problem so no reason to switch.
As pointed out before in this thread Plastilube is not rubber safe, you shouldn't be using it on pins.
PTFE is safe for rubber, I would think twice before using anything with ceramic particles or moly however.
Plastilube is mineral oil based (CAS 64742-01-4) per its datasheets and explicitly says on the tube never to apply it to rubber parts.
EPDM is not junk, and it's very common in brake systems, other manufactures are not going to stop using it just for ATE's sake.

Sil-Glyde works good.
Ive used that synthetic black brake grease and that works good...think it’s CRC
Honestly the 3M silicone grease works great...used that in a fleet for 7 years, and it never let us down. Can’t say the same for Permatex Green or Purple. Both have dried out on caliper pins for us. And they hosted a seminar for us once, showed us how to install it on the back of pads, caliper brackets and caliper pins. These people had us convinced it was made by Santa Claus and the Easter bunny in a joint venture to save mankind. And then half our brake jobs came back with stuck caliper pins and pads, six months later. No more fancy purple or green grease for us. **** you Santa! And you too bunny!! SHAME!!!

The 3M stuff is great and I used it until I tried the Mission stuff, same product different brand and less expensive. These are a great all round product, dielectric, safe for all body and brake rubber seals, it replaces quite a few cans.

Interesting how for the VW code TecDoc only lists the Febi and a SWAG code that I couldn't find. The Fuchs Renolit also doesn't seem to be available.
I guess this Febi is the safe bet, but there's also the option of getting Textar Hydratec or ATE "brake cylinder paste": https://www.ate-info.de/en/details/produkte/ate-bremszylinder-paste-180-ml_spanisch.
Plastilube is not for pins, it's just anti-squealing surface-lubricating grease: https://www.ate-info.de/en/details/produkte/ate-plastilube-75-ml
I got a tube of Wurth Silicone Lubricating Compound like 15 years ago. The tube actually says it's good for two years lol.
I use it on all sorts of things, not just caliper slide pins. It's great on o-rings, any sort of rubber dust boots, basically anything rubber. It's quite tacky so I often use it to hold the gaskets.
Never caused any swelling or dried up. I'm happy with it.
Having said that, when this one finally runs out, I will probably get something else, as Wurth products don't seam readily available here. 3M silicone paste looks very similar, so I may get that.
