I wasn't suggesting doing anything unsafe. Common sense should prevail but, alas, some are just interested in being "right".



the max.cut was put on the brake drum because the manf. said anything over that was unsafe. all safety insp. use these no's, as the cut off point, so personally I wont tell anyone to go over it, so if that's being "right" then I'm glade I'm "right". he can call any brake shop and I'm sure that will tell him what he needs to know.
The max diameter was put on there because the lining to drum contact would be minimal once the drum reached a certain diameter, NOT because of some danger of drum breakage (but you probably think setting batteries on the ground will kill them). Arcing the shoe ensures full contact of the friction material.

Somehow when mfgs. started putting max. diameters on drums people started this myth of drum breakage (that was never a problem before).

I'm not real big on old wives tales.
