I see there is caliper grease and caliper lube. What's the difference and the application? just the caliper pins? Lube or grease for the pistons themselves? I know that some just use brake fluid for lube on assembly - just trying to figure out what the different applications are.
To be honest I rebuilt a set of front calipers and reassembled and slathered up the pistons with caliper lube (or maybe grease, I dunno a permatex ketchup pack of stuff) - and wonder if I need to take it back apart and re-do what I did.... |

99% of the caliper lube I have seen is for aluminum calipers with steel pistons (Brembo sells caliper rebuild lube) I would'nt worry about it on steel/steel setups. I assemble them with brake fluid on the seals... and go on my way. I honestly believe it is more of an issue with 4 piston aluminum calipers than it is with steel 2 piston calipers.

I use a paste stuff, silicon grease, looks like vasoline. I don't know if it does any good but I don't think it will hurt.

For many years I have used VW brake assembly lube. I think it is NLA now. It is great for assembling calipers that may not be put into service right away. YRMV

No need to take them apart. You should be fine. It's helpful stuff when you need to get the pistons past the new cylinder seals. It's a synthetic so it won't hurt the seal. It's also a fluid (in a sense) so it won't compress and will be innocuous and invisible in the system.
