Otherwise ignore the locking bolt and just use your fingerspitzengefühl. I do this with my spyres. I push the brake arm already a bit in while installing the cable so less lever throw is necessary.
Spyres have 3mm adjusters for each pad and are designed to work with the arm going all the way back but without any slack, hence the barrel adjuster.
Do the Hy/rds need a bleed? They have a fair amount of throw but shouldn't be hitting the bars.
