I'm wondering about what grease you could get to inject through a zerk that
would be appropriate for the caliper?  Audi calls for the parking brake
mechanism chamber to be filled with G052150A2, a high-temp lithium
grease.   They supply the stuff in a small plastic tube that, among other
things, says on the label that brake cylinders, pistons, cups and other
parts never should be lubricated with grease, mineral oil or similar products.

My other concern is the amount of pressure one can generate with a grease
gun through a zerk.  could you disturb the mounting of the threaded rod the
piston rides on by overpressuring the parking brake housing?
