If you're using a line wrench and it's trying to round the nut try clamping the wrench jaws with vice-grips.

q) you've advised that the brakes
are a link system. so if you pull
the front brake, it operates the rear
brake. how does the
bike calculate the correct %
of braking?
i was taught to use 70% front
brake and then 30% rear brake.

q2) how do you bleed linked
brakes?

many thanks

The linked brakes are operated with the foot pedal not the hand lever.
The pedal operates the rear caliper with 32mm pistons and the front right with 25mm pistons so you get more braking in the rear than the front using the pedal only. You add front braking with the hand lever.

Bleeding linked brakes is like bleeding car brakes, you bleed at one caliper then at the other.
