Permatex purple brake lube

The following quote is from the Toyota Parts Direct website and the practice aligns with the FSM instructions for overhauling Toyota disc brakes.

TOYOTA OEM RUBBER GREASE 100G (Lithium Soap Based Glycol Grease)​

Part Number: 0888701206
Supersession(s): 08887-01206; 888701206
Ever open up your Factory Service Manual, and while thumbing through the brake section, notice the words "Lithium Soap Based Glycol Grease"? Well, THIS is that grease.

Think of it this way, if a rubber piece touches ANYTHING metal, use this grease liberally. Dont have to overthink. IF rubber + metal = THIS grease. If you are looking for the disc brake grease for metal to metal contact then use TOYOTA OEM BRAKE CALIPER GREASE.

OEM. Made in Japan.
You are mistaken. It is used on internal square seal during rebuild/assembly of the caliper. It will not survive the caliper pin heat levels and metal on metal friction, it is made to be friendly to rubber and brake fluid.
 
Oh i know what the toyota says. That stuff doesn't stand up to heat and washout anywhere near silicone based stuff like silaramic, M3 paste and mission
no it doesn't last more than a year, but hey, I have no problem servicing/lubing up the brakes every year (scion tC here). But at least it didn't cause the sliding pin bushings to swell up like the silicone the dealer used way back in the day. Had to replace all those bushings because of that but never a problem with the correct grease..
I wish it lasted longer but hey it doesn't and I never have had a problem using the Toyota rubber grease. If that means less problems for me, then I'm happy.. (y)

EDIT: read your post claiming it doesn't survive heat.. It does but only a year. I have high performance carbon/kevlar pads that liquified the regular white shim grease Toyota uses! Had to go to the Permatex Purple ceramic solids grease and that doesn't liquify on the back of the pad/shims! But.. the Toyota rubber grease on the sliding pins did not liquify so yes it does survive high heat, been seeing that for years on mine.

Just went to check on the MSDS sheet to prove you wrong and it looks like I mixed up Niglube RX-2 and yota rubber grease.

well at least you checked and found out your correction.. (y) I just know I've been using the Toyota rubber grease and the one drawback is it needs to be re-applied every year.. Easy enough I should be servicing the brakes every year anyway!

Your dealer didn’t use silicone grease on these pins, that’s almost a certainty.
So you’re drawing wrong conclusions based on one bad experience and second hand information, because in reality you have no idea what the dealer used.

On the other hand if your happy with applying Toyota grease every year, then there is no need to mess with that routine.

Good to know, I will inspect the pins on my Toyota now that you mentioned their grease doesn’t last long.

It's funny that you assume that I don't know or am not aware of what the Toyota dealer used back in the day.. And how would you know that I didn't question them on what they used? Of course I did, and they showed me it was 3m Silicone grease in a brush on cap bottle. So that's already a certainty that I did check and they assured me it was the "Correct lube" for the pins, after a month or so the sliding pin bushings DID swell up and I had to replace them. You don't have the authority to tell me that my own experience was "second hand information".

Amazing that you claim I don't know what was used, do you just like to tell people what they observed? When none of what you said was true of my life.
 
3m silicone grease is a commonly recommended grease by multiple OEM's. I dont know what happened to your pin bushings but I HIGHLY doubt it was 3m silicone. Chemistry and statistics say it is something else.
Could the 3m paste been contaminated? Old grease on the brush from hundreds of other cars/pins?

You saw what was showed to you. Since it wasn’t you that performed the service, you cannot claim you know what was used.

No you don't get the authority to tell me anything of what I experienced.. End of story.. You want to argue about my life it won't be responded to after this.. You obviously like to tell people what to do, that won't be happening with me.. Have fun talking to yourself.. this is over now.

It’s simple logic man. If I had someone do something for me, I cannot claim to know 100% what was done and how, unless I followed them each step of the way. What’s so upsetting about stating such a simple fact?

Sounds like they showed you what they say they used after the fact. Maybe they lied to you.... Unless you watched the tech open the bottle, get the lube on the brush, and apply it to your slide pins, you have no idea what was really used.

I don't need "authority" to say this either 🤣

He said he uses lithium soap based grease with no ceramic fortification, the dealer used silicone stuff. If the dealer just slapped some grease on even with a courtesy wipe he could have mixed the two types together.
silicone is not even mentioned here, im ASSuming it is very much not compatible

Discussion here is getting heated and rude. We don't know what happened and should not point fingers one way or the other.
I am making an assumption that silicone and lithium grease was mixed.
 
Watched this last night .


I hate those rated to 3000 degree claims. It is still base silicone that will get fried at MUCH lower temps they just added abrasive particles and some ceramic particles. So you just got a bunch of abrasive crap with the silicone boiled out and gone.

What we know for sure is that the 3m silicone grease would not have caused the rubber bushings to swell only after a month. Pointing out that something doesn't add up is not being rude IMO.
