Hi Doug, As long as your brake shoes are contour ground to match each drum, I don't think it would present a problem. I seem to remember my old-timer brake shop dude telling me that .060 was the safest one should go... Also a major factor, how much and how hard will you drive your 300H? I've permanently solved the awful, center-plane front brake issues on all my cars by doing disc conversions; I've kept all the drum parts so that the cars can be returned to stock later on, by the next owners, but sure as heck not by me.

The left front drum has been previously turned to .070" over 12". The service book says that the max allowable is .030". How dangerous is it to still use this drum? The right front drum has not been turned and should be cleaned up at less than .030". I am planing to use the left drum as is. Will different inside drum diameters cause a problem?
