I'm not so sure the adjustment is for setting the pedal height, as it is for pedal freeplay?
The book CALLS it a pedal adjustment and then cautions about brake drag. Symntecs maybe? I guess the important thing is to have enough travel to operate, without preloaded pressure on the master cylinder.

The only stop for the pedal is the master cylinder push rod. It will go way, way up without the rod connected. There is no free play adjustment and no way to get brake drag unless something else stops it upward movement.

DOH! I keep forgetting the pedal "pivot" reverses force applied on the master cylinder rod. The spring on the pedal prevents the rod from exerting force on the master cylinder plunger.
