G'day Mungo,
On the B767 the autobrakes activate well before the nosewheel is on the ground, when 'truck untilt' occurs according to the manual, and from aircraft to aircraft the level and speed of application varies quite a bit, regardless of the setting, and the ensuing pitch control is not a problem even at max autobrakes.
The B707 I flew in my previous life didn't have autobrakes and the brakes were not applied until the nosewheel was on the runway.
Regards,
BH.
