'15 RAV4 brake slide pins stuck...

I used that when Mission was not available, it works fine.
Mission

I’ve been using that since before I heard of mission. I use this stuff on everything from drawer slides to brakes to electrical connectors. It’s a good deal for the price and my slide pins are still well lubed every year. I could probably go 2 yrs easily.

I am not a fond of the toyota's reddish pink grease. I just use regular silicone paste.

I've been using the black CRC brake lube for years. It seems to work as well as anything else.

Caliper pins (and boots) should be considered routine maintenance items...especially in wet, snowy, and/or salty climates. It literally takes one minute to pull, clean, re-grease, re-install, and torque each one to spec. Very convenient to do this once a year while rotating tires. It's not worth waiting for them to gunk up.

And check the pad ears too, make sure they haven't swollen from rust.

I like to grab inner pad, rotor, and outer pad like a sandwich and give it all a rattle back and forth. I can tell by feel if they're too tight.
