WTF Front Brakes?!?

No One Ever mentions 'Drawing Down' or annealing the weld to remove stress risers or 'softening the weld' just enough to increase weld life.
Any suspension we built for Indy Cars is heliarced & after cooled we would use acetylene torch to draw it down; as you warm with torch the metal goes thru colors, gold first, IIRC, then purple/blue, then to grey(too hot). This is done to improve flexability of the weld.
