What KIND of grease, Brett? Was it the Audi spec? I've seen rust come
back under the boot without it encroaching on the pins themselves. I've
started to make sure there's a little G000650 in the groove on the pin
where the boot seats. I've disassembled several calipers where I've used
G000650 as the lubricant over the last five or six years and found no rust
on the pins. I wonder if there is some anti-hydroscopic property to the
Audi-supplied lubricant missing from other brands??? Or maybe it has a
clinging/coating property others lack???
