Guide pin grease

[Moshikobr]

Hey,
I want to grease the guide pins in the caliper and wondering if generic silicon grease for rubber up to 200 degrees should be enough for this job
Thanks

No, I’d go with a grease that is specific to brake applications. That will ensure the rubber doesn’t swell up or crack due to incompatible grease. I’ve used both CRC and Permatex and they worked great.

I use 3M silicone paste. They do make purple "slide pin" grease, so you can look for that as well.

Can you get Sil-Glyde in your area?

Can't find this stuff anywhere.
Here is the TF data sheet on it and eBay is wanting $139 for it.

Anyone have a proper source for this 3M product?
Amazon doesn't carry it.
May have to find an alternative.

I believe this product was discontinued. I fell down a rabbit hole looking for an alternative. Closest I could find is possibly Molykote 111 if you’re seeking a general use silicone “paste”. Temperature range is close to 3M product, supposedly safe for many materials.

Thank you sir for that information.
Good to know there's an alternative as I'm a 3M fan.

Super o-lube should be good for this?

That SUUUUUUUCKS. Because it was absolutely AWESOME. Best damned silicone paste I ever used.

I never used it but I’m sure it was worth the hype. 3M makes some fantastic stuff. I’m guessing their pivot away from it could’ve been due to it containing PTFE or something. Their data sheets state they didn’t knowingly add PFAS/PFOA but I’m guessing there’s something in the proprietary cocktail they don’t want to make anymore. Such a headache when a good product disappears! Happens too often for comfort in manufacturing.

Maybe? I like how 3M Silicone Paste specifically called out its use for brake systems as it likely had compounds to reduce friction and prevent it from gumming up. Advertises itself as a jack of all trades. Molykote 111 doesn’t go that far, but I was finding some references like Jaguar requiring only that silicone for caliper slide pins.

Not sure if the Super O-lube pictured would be good for brakes as well. It looks like a knock-off of Parker super o-lube with no discernible manufacturer. I’d try to find a reputable big company for safety’s sake.

Im still fairly comfortable recommending a product specifically for brakes if it’s only brakes we’re worried about. That 3M product would’ve swayed me though if I could get my hands on it. Lots of stuff I could’ve used that on! I did new brake pads and rotors on my Titan and as I tow a camper on small mountain passes, I wanted a reputable brake grease for the pins. Found lots of love for the black CRC synthetic caliper grease online so I went for it.

Here’s some good similar discussion here https://bobistheoilguy.com/forums/t...-greases-for-caliper-slide-pins.345435/page-5

Molykote is what's called for for the pad clips, though I couldn't get it so I used the same Sil-Glyde. At least I swapped to ceramic pads so I should no longer have the caking up of corrosive brake dust gumming things up.
