How to Clean Your Brakes - SUPER EASY - Mazda 6 2018

actually the pins get stuck coz non-silicone greases can attack the rubber boot, then you get holes in them, water gets in and corrodes the pin and the hole it goes into

for the caliper pins i just use plain high-temp silicone grease (no solids). this part doesn't need a lube w/ solids like ceramics and metal powders

for the other parts like the brake pad tabs and shims you may use a brake lube w/ solids

So that explains why one of the caliper pins looks like this:

Can you explain further about this "lube with solids"?

yeah you got corrosion in that one pin. water got in somehow, these pins were 13yo when i took this picture. no corrosion, and no wear coz caliper pins aren't subjected to high loads. so use a lube that doesn't damage the rubber boot (plain silicone grease)

as for lubricating the contact points around the brake pad... well the pads can get super hot which boils off the oils from grease that's why metal powders are used (copper, silver, nickel, etc. even ceramics).
