Permatex purple brake lube

[Hall]

In the past, I've seen comments from people who had bad experiences many years ago (??) with Permatex's Ceramic Extreme brake lubricant. I've been using it for a number of years and it's my preferred brake lubricant. I just replaced the front/rear brakes on our daughter's car and were previously replaced ~4 years and 45k miles ago. When I removed the slide pins to clean and re-lube them, they still had a thin layer of the purple lubricant. The slide pins still slid freely and the lube was not sticky or gummy at all.

A couple people have indicated that Permatex made a formulation change and that the complaints were valid but with the new formulation, they solved those complaints. I used to use Sil-Glyde on all slide pins and while it is highly praised, my experiences turned me off from it. On more than one car, the slide pins were practically glued in the calipers. The lube turned extremely tacky. Just my observation.... Don't be afraid to try the Permatex stuff again !

Good to know @Hall

I'm doing a four corner brake job on a friends '05 Sequoia tomorrow and that's the only open can of brake lubricant I have on my bench.

I've had very good results with this lube on quite a few vehicles so far. Thanks for your comments and experience.

I wonder if they really have changed something? When I've encountered it in the past it has hardened to something like crumbly purple cement

that's definitely different.. my experience with the permatex ceramic solids or Purple grease it never dries up. I never used it for sliding pins since Toyota is very specific about the Lithium soap grease to be used..

The one thing that the Purple grease is good for is high temp pads, putting them on high performance pads that generate a lot of heat, that grease can go to something like 3200deg fahrenheit! wow.. For that they're perfect..

There are so many options why go there? I've used it on my Honda with poor results- it gets Raybestos silicone lube now.

I've been using the orange permatex lube with success

My understanding of these 3200f claims is that the regular grease oil/thickener components of these super greases is still only good to the general 400 -600F range and that the ceramic/moly/teflon/whatever "marbles" components are what are left over and still present at very high temperatures. To me, it seems like dubious marketing.

I'm with dfarr67 - the old standby real silicone grease works well for enclosed pins. High moly paste for exposed to weather areas.

It’s hard to trust something once you had a bad experience with it. That’s just how we are wired to operate.
I too wasn’t happy with the Prematex brake lubricant and since switching to silicone paste, I have never used it. I see no reason to give them my money.

I understand but my point is, I have never had a bad experience with it. I used other products, including Sil-Glyde, and then decided to try this. In my usage, I've had zero issues. If you choose to use something else, I'm not gonna try and change your mind (beyond this thread)

I totally get it, if it works for you, that’s great. And thanks for sharing your experience. It’s a readily available product from just about anywhere, so I’m sure a lot of people will find your experience useful.

Sil-Glyde is highly praised here, yet it hardened up on you and I have read similar complaints from others. I’m sure the product I have used without any issues would probably have similar complaints if enough people used it.

Not sure why different people have different results with the same product under seeming similar circumstances. That’s life I guess

It was previously discussed in this BITOG thread.

Permatex website now states safe for rubber seals and SDS shows the grease is ethylene glycol based now instead of petroleum grease.

well that may be marketing but I tried the "regular" brake grease when I switched to carbon/kevlar performance brake pads and the heat from those pads liquified the "regular" grease. Smelled like a BBQ! Switched to the ceramic solids Permatex grease and it never has had any issues on the back of the pads (shims) and the edges "ears" of the pads.. Still in the same condition after a year of applying it.

But I would not use it for sliding pins no matter what they market.. but hey that's me and following what Toyota recommends for their sliding pins.

I certainly thought I did something wrong when I saw it harden and sticky more than once but I mean, what could I have done "wrong" ? When others confirmed what I was seeing, I knew it was the product and not me and I quit using it.

Yet people still discredit the product....

Good to know they changed something in it. I’ve had to pry pins out before with that stuff on there. I always put Sil-Glyde on pins except at work because they won’t buy that and they now provide us with CRC Brake Grease which seems to do ok on pins. They will get the purple or green stuff for the people who want it but none of us use it on the pins. Now if this stuff is ok for the pins and the bushing on the pins then I’ll be ok with using it on there.

I have used Mission Silcone since @Trav recommended it a few year ago. It has worked perfectly on every brake job.

I run two Volvo 240s all year and both go to Stowe VT during the winter. One is my wife’s daily.

I just replaced the front pads and rotors on her car after 28,xxx miles. The pins and caliper surfaces were in excellent condition and easy to remove. There was still plenty of silicone on them.

I’m not going to try another product since this one works so well.

I'm sold on the mission for caliper pin sliders! I used to use syl-glide and it worked well, but mission does not thicken or gum up over time.

I've been working through a tub of the black CRC brake lube. It seems fine, though we don't have salt here.

3M Silicone paste on pins, Permatex purple on wherever metal touches metal……just saying!
