Shot peening?

[jmbrodsky@domain.elided]

     Binders,
     
        I'm of the opinion that the top surfaces of Master Cylinders are 
     deformed because after they're rebuilt, they are hand tossed 
     (sometimes worse) more than a few feet into a large tub withmany 
     others in it.  Thus they bang around together until they get covers at 
     the end of the line.
     
        Block sand the top, or surface sand it before you put fluid in for 
     the first time, then rinse well with water, dry, and bench bleed with 
     plenty of new fluid and you should be fine.
     
        Why is it that the rebuilts seems to last only a few years at a 
     time, before they go all the way to the floor or creep at the light?
