Brake Drum Maximum Diameter

Recommended Posts

I need to have the rear brake drums on my 1958 A-120, with RA10 Axle and 12"x2" brakes.  Does anyone know what the maximum turn-to diameter is for these drums?  They are already at 12.120".

Thanks

120 over must be close to the limit

most drums allow 0.060  , some folks used to put some thick gasket paper between the shoe and friction material

then rivet together ,   would then "arc" the shoes to fit the drums

IIRC the original question was the max spec + new,.000 ,which did not matter much then   good lining good steel +size and mass

dont know of any listing but it could be shown in dealer  master service...only kb books here..

if he took it to a shop usually that is the first question ins requires them to ask,today with china %^$*(  and bad cheap parts in the entire component it is likely to fly apart....$$$$$

I can cut my own ( dont have the arbor over 12")up to 30"

'90 and newer it is marked on drum or published

for mama's rotors 2-3 cuts of .010 ....20K miles or 3 yrs after that web is too rusted to be safe  60-40 never get cut most are trashed by the 2nd set of pads  and or warped from 1st week
