Brembo calipers
 

Anybody rebuild the brembo calipers on a 2000 base 2.7 manual? I can’t find the o rings. Only dust caps that say they don’t need o rings, they are supposed to be 1 piece now. Sounds scary to me.

If its a 1-piece, it means theres the O-ring for the piston, which is square in shape on a cutaway, and may be attached to the boot, but shouldn't be. Give the cost of rebuilt and used calipers, rebuilding them isn't cost effective anymore, given what you'll pay for new seals, the correct rebuilding grease if you don't have it. I've done them before myself, and you'll want some soft plastic tools to play with the boots sometimes, I like shin-etsu rubber softener, allows rubber to be pretty pliable.
