Brake caliper sliding pin grease

[shortyb]

So, I'm preparing to replace rear brake pads on the GLI and realize I don't have any silicone grease for the pins. I know that a quick trip to the big box auto parts stores could score me a few packets of Sil-Glyde, but wondered about other/better silicone greases. After searching, it seems that Mission Automotive silicone marine grease is very well respected and recommended. But where the heck do you get it now? Only place I could find was on eBay for big $$$. Found some CRC silicone grease (ceramic fortified 100% silicone) safe on EPDM and Nitrile rubber and all plastics, clear to slightly translucent like Sil-Glyde that looked promising. Set it back on the shelf for now and decided to post this in an effort to locate some Mission grease. Any ideas? Is Mission Automotive still in business?

Oh, wow! First 3M silicone grease disappeared and now Mission?

A Google search suggests that maybe there is an ongoing silicone shortage: https://www.spendedge.com/white-pap...ement-intelligence-thought-leadership-series/ Maybe? It is very difficult to fact check.

When I looked, every response was Sil-Glide....so I got Sil-Glide.

May end up getting some more. No problems with it, but intrigued with the Mission product. However, 8oz. @ $40 it will go in my estate inventory as there should be about 7.5oz left when I go .

Sil Glyde is what I used to use 20 years ago, but it's probably one of the worst "silicone type" greases at the store. There's a reason silicone is not mentioned anywhere on the tube. It's not silicone. The "Sil" in the name effectively tricks everyone.

I use Motorcraft silicone grease or CRC Silaramic.

I too had very good results with AGS SIL-Glyde, never felt I needed anything better. Is it an emergency brake job? If not, then just get the grease before doing it, make sure you have all the tools before you start as well. Some pads ship with grease packets, e.g. PowerStop and Bosch.

Sil glyde makes a ceramic that’s safe for all rubber/plastic and priced well. I used it last spring on the whole brake job and nothing negative to report.

Correct. Sil Glyde is castor oil grease with maybe a smidgen of silicone (maybe).

Looks like Amazon has some Chinese sourced silicone grease. Maybe the Super Lube brand of silicone grease is a #2 grease that might work??

The Ford XG3A silicone grease is still available.

I’m not sure I’d use a ceramic fortified silicone grease on slider pins. Just pure silicone or maybe m-77 which iirc is silicone with moly.

Super lube silicone has ptfe in it which I wouldn’t be concerned with in this application besides heat exposure.

If it is made for caliper pins why not? Worried that the additive will interact with the rubber?
I had good luck with CRC silaramic.

All that is required is silicone grease with no additional additives like ceramics or moly. This one will do the job and will many more like the stuff from 3M. A very thin coat is all that is needed.

Is sil-glyde the best.. no does it work fine.. sure.

Sometimes the lubes with "extras" turn gritty, or interact(swell) with the rubber on the guide pin.

I’m a fan of silaramic too. Just not a fan of too much solids in the pin recesses and gaps.

Super lube has a silicone-only grade 2 grease also:https://www.super-lube.com/Content/...hnical_Data_Sheet_O-Ring_Silicone__Grease.pdf

One would have to get over the idea that the label does not include "brakes". Is there a difference in a silicone grease that states dieelectric vs. brakes, vs. o-rings?

14 oz for $20 : https://www.amazon.com/Super-Lube-9...1-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&th=1

Does it harden and build up crud?

In South Carolina we just spit on the pins and the back of the pads....

Kidding...kind of.

I use Sil-GLyde. Never had an issue, but not a big deal in the South.

I have mission silicone grease, but it looks discontinued on amazon. I'd use what Trav posted its good to 570F.

 

[TiGeo]

Motorcraft caliper grease is what I've been using for years.

I was going to say, in SC you can use pretty much whatever. No salt, no problem.
