Is this proper lube for caliper slide pins?

[mclasser]

Will be doing a brake job this weekend. Is this brake lube correct for caliper slide pins? It appears to be silicone-based, which is what's needed for slide pins. The reviews I read seem good and AAP stocks it. What do you guys think?

 

[Bgallagher]

yup! I use the NAPA version of this. Works great. I use it on the caliper pins and the sides of the pads.

Any auto parts store will have a lube specifically for this. There are multiple brands.

Some even offer it in small single application packets.

Yes and it works well.
Can also be used on other rubber and plastic parts.

Permatex makes a green brake lube that's really good stuff.

Just make sure it is the highest quality stuff you can find. I use Wurth, I get it from the Acura dealership.

If the slider pins seize from a bit of neglect it usually means time for a brake job as the damage is usually bad.

If you use quality silicone grease in the slider pins, you can go 2 years between applications if someone forgets to service them.

That's an excellent brake lube that has been around forever and lots of people still claim excellent results with it.

I tried several of the new fangeled brake lubes and have returned to using either Sil Glyde or a real silicone brake lube.

Both The Critic and I like to remind people that the "Sil" in Sil Glyde might refer to silica more than silicone. The MSDS (the old, useful ones) show silicone to be a VERY minor component of Sil Glyde.

ANOTHER brake caliper lube thread!?!

Nah, just kidding. Yes, Sil-glyde has a very good reputation and works well. No it is not silicone based, and actually has a rather low silicone content. I have used sil-glyde many times with good results.

That said, it does not seem, to me, to last as long as Motorcraft XG-3A silicone brake caliper grease. And neither hold up very well on exposed pad ears (currently trying jet-lube mp-50 moly paste on my truck for that).

I have used both nothing as well as any kind of grease I had on hand (wheel bearing, chassis, white lithium, etc.) None ever resulted in any issues whatsoever. On my 89 Accord I didn't even pull the pins to lube them for the first 10-12 years I owned the car. I would call this decision non-critical.

Yes, this is my favorite. I use it at work daily.

I see two MSDS's for Sil-Glyde. One says almost nothing. This one says 1-5% Polydimethylsiloxane (silicone), but it also says 5-15% Silicon Dioxide, Amorphous, which is likely a way of getting around listing the actual polymer composite that is created from the SiO2.

Together that's a fair amount of silicone lubricant, 6-20%.

I've been using it for a while and it does a good job.

I tried it a couple times and went back to Sil Glyde. Permatex green dries out fast.

 

[Falken]

Hate to be a Wurth shill but their silicone grease is bulletproof and never dries out.

If someone was to neglect their sliders for 5 YEARS I'd put my money on it that they wouldn't seize if the boots didn't tear.

Really. Get some. Works great on door seals too:

I bought a tube of Sil-Glyde years ago it works great, stays put and does not swell the rubber boots. I tried the Ceramic stuff (Permatex Purple) did not last, dried out. Pickup some Molycote M77 for the pad backplates its the same type that Akebono provides with a new set of pads.
