1987 PT40 Grease and Zerk Fittings

[worktohobby]

Hi all,

Do I need to use a special lube for my brake Zerk fittings? I could not
locate the "Stopmaster" NLG1 grade #1 type. These are self adjusting
type brakes.

Also, what is the recommended lube for the other bus Zerk fitting? Or
does it matter so long as it is grade NLG1 grade #2? Nappa has like ten
types of this stuff and they recommended simply using the plane lithium
type.

Thanks for the help,
