Title says it all. The 5,000lb front axle of my 1965 C60 features 14x2.5" brakes. I was finally able to procure new drums, but I'm not sure what the torque spec is on the bolts that hold 'em onto the hubs. They're grade 10 bolts 1/2" diameter, so I guessed 80lbs/ft. However if that's not tight enough, now is the time when it's still pretty trivial to take the hub back off and tighten.
I just didn't want to warp my really expensive new drums!
