I’ve used silglyde, 3M silicone paste, and now Raybestos silicone paste. Never an issue with slide pins with any of these
Brake caliper sliding pin grease

If it's a Toyota, probably want to use their red grease.
Not if he was using silicone before that.
I also had purple failure. Turned gritty seized up.
I’m going to take a torch to it today and get the pin out. It clearly states on the bottle “safe”, and lots of you tubers use it. Doesn’t work in Ohio!
Waited most of the afternoon for Amazon to deliver the grease, but she is all buttoned up. Looks like pretty much JIT. Grease is a very good, thick paste. Thanks @Trav.
These are the original pads and lasted for 112K. Trying out some Ate ceramics this time. Not really a huge fan of ceramics due to typical lack of bite, but hear the newer Euro formulations (Ate, Pagid, Jurid, Textar etc.) are much better in this regard. Friction rating is GH, original TRWs were FF. We'll see what happens.

I would skip Toyota grease. The pins get stuck for some reason despite grease being there and no corrosion.
I had a hard time believing his when I read people claiming to his, however I decided to check the pins few months ago on my Toyota and all of the pins, except one, were stuck. And this is a 100% Texas car, never seen salt or snow with only roughly 25k miles when I checked the pins.

Can’t remember when i purchased this tube, definitely more than 7 years ago, still have some left, have used it on all my vehicles, and vehicles I’ve worked on, no problems on any of the slide pins.
That's because it's a grease made for internal parts on brakes such as super piston seal. It's the RX formulation.
You want RN formulation that has solids in it.
Or just get silicone paste in plain flavor or something with solids like CRC silaramaic.
Internal brake parts are lubicated by the brake fluid? why would you want to use a grease?
Also I avoid silicone with solids not reliable esp. in salt land.
Plain silicone such as 3m, mission etc, or sil glyde.. only IMO. on pins..
now on pad ears and backing I use pastelub. 40% solids.
You use it on square piston seal in the caliper. It plays well with brake fluid.
It's niche over here in the USA but the Japanese have insane auto inspections.
Even a hint of any fluid on caliper ? Complete disassembly and inspection.
They often replace the caliper seals during these inspections or just use the grease to reassemble. I think they also have big multi-year inspection things that they do it sometimes too.
I think i linked a Russian language video on a Japanese inspection here once. Very strict and thorough.
They also had a "tier" system in their shop where you had a new guy working on brakes but because it was brakes/big safety item his inspection work was reinspected by their main mechanic with all the certs.
But this might be cultural / company thing not law.
FYI, I reported here that Pastelub changed formula during Covid. I talked to Gary at GWRAuto in Florida and he now has the original formula back in stock and I ordered/received 6 tubs.
