Brake Booster Rebuilds

[RED71Z]

I bought a booster from O'riellys today for 100 dollars.The shaft was to big so going to swap shafts tomorrow.Will reply if there is a problem.

centric 160.88031 appears to be a perfect match for the 74. the pushrod was even preset to the correct length. it's going in now. 

 

the junction between the booster and master was dry, crusty, and full of crud, but no signs of an active leak from the master cylinder.

does anyone know if the pushrod/master should be greased?
