Permatex purple brake lube

Permatex purple did freeze one of my slide pins so I’ll never use that stuff again. Sil glyde makes a ceramic silicone that’s supposedly safe on rubber, and has been so far. Decent price and blue in color so you can see where yo put it. So far so good.
 
This thread has piqued my curiosity. I've been using Sil-glyde for several years and have been happy with it, but I'm always willing to try something new. I can't find it now, but someone mentioned Permatex orange, so I got curios and went to the Permatex website to see what the difference is between the purple and orange. Both have a very similar temperature range (-40 - 3000°f for the purple and -50 - 3000°f for the orange). But the purple is recommended for mid sized cars, vans and SUVs, while the orange is recommended for trucks, trailers, performance vehicles and hybrid/EVs.

Why wouldn't the orange product be suitable for all applications, eliminating the need for the purple? Is it nothing more than marketing, so they can sell more product by offering different brake lubes?

I'm leaning towards picking up a bottle of the orange, next time I do a brake job. But I'd like to hear what others here, who have experience with the two, can share.

For slide pins I've actually defected from Mission to the AC Delco stuff, which is also highly recommended here.

I can't speak to longevity as I haven't torn anything down where the AC has been in use for any period of time, but I sure like the tacky consistency. It's "wetter" and yet stickier than Mission.
 
Just did my front brakes, here is the pin with the lubricant on it. I used Wurth Silicone compound about three years ago and 50k miles, never touched them since.
Except for turning black, it still had the same consistency as when it was put on.

Do they charge more for the orange ? If not, that's dumb on Permatex's part. Just make (1) product (in this case, the orange) and run with it for ALL applications. Personally, I find it silly to have (almost) identical products that are different for marketing reasons.
 
I’ve been using Syl glide. However, I do take my slide pins out during Spring and Fall (switching between all seasons and winters). The syl glides aren’t great imo in keeping slush out during the winters as I’ve had a couple of times when the pins were partially stuck. Going to move away from syl glide when I run out of the tube and switch to the permatex purple
For metal to metal contact areas, I’ve had good luck with CRC 5359.

Neighbor has 3 vehicles in the family and slathers the purple permatex exclusively and swears by it. We compare notes during the tires change time and never seen him have issues with slide pins being seized like I’ve had.

The orange Permatex is silicone based with ceramic and the purple is Ethylene Glycol based with ceramic particles. On the Amazon site, Permatex orange cost $10 more than purple for the 8 oz. bottle.
 
I use the Orange Permatex with good luck. I chose it over the purple because at one time, purple was supposedly not compatible with rubber seals like slide pin boots.

Is the Toyota Rubber Grease ethylene glycol based? Its what they recommend for their vehicles

I'll say that neither one will withstand bi-weekly wheel cleanings if you use real wheel cleaner.

 
Every couple of years around the time when the Märzenbier hits the store shelves I'll pull the old hay wagon into the barn and disassemble the brakes, clean everything, replace anything that doesn't pass inspection, and then I slather it all back together with these two separate lubricants. The Sil-Glyde goes on the glide pins, glide pin boots, and caliper piston boots prior to assembly. The Cera Tec goes on the back of the pads where they come in contact with the caliper, on the caliper carrier and shims where the pads sit and on the ears of the pads themselves. The Cera Tec stuff just doesn't seem to be affected by water spray, heat, vibration, etc. It's always where I put it two years later.

Fred Flintstone might have had more swept braking area than my car but I bet he was squealing after a few hard decelerations. These lubricants keep things smooth and quiet... just like Wilma likes it.

Question is, if you washed those wheels on a regular basis (like most cars), will those lubricants remain resistant to cleaning products? That's the million dollar question.
 
I have had good results with CRC Silaramic. Silicone base, works just about everywhere.
Silaramic did a decent job of staying on and resisting washout when one of my pin boot was slightly torn. I have nothing to compare it to but I will be sticking to silicone based lubes for pins.
 
Toyota rubber grease should not be used on slide pins.
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.
