    I've been using this stuff for years, mainly because I have a big tube of it. I never really looked into the silicone lubricants that much, but there have been a few references to them on this forum.

    This thread is about slider pins, not brake squeaking!
    +1 Agreed, the Permatex green stuff SHOULD NOT BE USED for caliper pins,

    I learned the hard way, it will swell up the rubber boot and make it impossible to re-install, dirt will get into the pin shaft.
    Also, the swelled rubber will cause the caliper pin to stick causing squeal and rotor wear.

    SIL GLYDE is the best for caliper pins, no rubber swelling and no turning hard under high temps

    Don't give bad advice if you don't know what you're talking about, ok?

    Funny, because the OEM grease doesn't look like any of the clear silicon pin lubes, in fact it looks a lot like permatex green, with a brownish tinge after use of course. I mean, the service manual doesn't specific a "silicon only" (in fact it says "rubber grease")

    You conveniently linked ONE bad review, from 2012 from a guy with a 1986 Subie; I doubt the rubber used in the 2015 Mazda is the same quality/composition as the rubber used in his old subie as the OP in that link mentions (with who knows how old brake parts).. Why don't you link the entire item, where it shows the overwhelming positive reviews, mostly on recent cars https://www.amazon.com/Permatex-2411...cm_rdp_product., instead of direct linking one poor review, that conveniently hides the rest.

    For most if there is swelling it's probably from over application. Meanwhile, further searching on the product shows little evidence of "it caused damage". Most of the feedback is actually very positive. If anything, you are the giving bad advice and spreading angst, and by your selective review picking it's pretty obvious. I'd bet 10 instances of "I use this all the time", "I use this on multiple vehicles", "Works great" etc for every one or less negative post regarding the product, that isn't just repeating what someone else said about the product being potentially damaging. And the negative post is probably from someone with an old ass car too (another topic often mentioned when talking about petroleum/vs silicon lube on the rubber part. If you look around Amazon (since you posted from there and they have reviews), look at the other permatex brake quiets while you are at it. These commenters pretty much are listing 2000+ cars not some 1985 car. I guarantee I stress my brakes more than the vast majority of the users in this forum so, I'll get back to you if my boot swells.

    The other factor is where people live. I have lived in Mn and Alaska most of my life. But in Minnesota especially we battle salty roads, and snowy frizzing moisture. Its an endless battle. Brake lines, suspension bolts, etc etc get so corroded that many times we just cut stuff off and replace, kinda sucks. Thats why I anti-seize EVERYTHING on the exterior of EVERYTHING I own. So maybe in some parts of the country a guy could reassemble the caliper pins DRY and the owner would be ok, in other places grease, and where I have lived max water repellent is needed. just a theory, different strokes for different folks.

    If you are lucky, you can ask CRC customer service or sales for a sample pack and it will include some stuff for you to try. Last time they gave me their entire line of brake service lubricants and cleaners for free!
