Anyone know anything about disc brakes?

Wanted to talk about hope brakes mentioning 'grease' leaking being normal.

My comment on that was based on getting some brakes back from a service by Hope. They lubed the pistons with Hunters, and when I pulled the brake, you could see a very small amount of lube seeping from around the piston where it entered the caliper. It pulled back in via capillary action as soon as let off the lever a bit. Asked Hope, they said that's normal. It's this side of the seal, nothing is leaking past the seal.

But also, as noted by others, the bottle of Hunters leaks like fuck on it's own on a shelf, and I have no idea why
