re the steel brakes on the classic...some figures I keep in the back of my head and I emphasise this is for a max stop on a T/O roll...
MTOW 377.8....... 110 kts
Intermediate 330 T ...... 120 kts
light 285 T (equates to max ldg wt)..... 130 kts
max brake application at these speed / weights and best get a call out to the boys in the little red trucks because the best outcome is a bunch of blown fuse plugs..... the worst is toast !
Hope this is of some help
