I have taken several (9204) Brake Boosters apart recently.............

Other than glass beading to remove rust what do the pros do to condition
the metal surface, prior to yellow zinc plating.....

I'm thinking that running the booster halves thru a vibratory tumbler/shaker
would polish the metal to look "as new".....\

ALSO, where might I find new replacement plastic/nylon "parts" that fit
on back of booster close to firewall ???

Thanks, Chuck
