I secured the star adjuster until the rotor was immobilised and then loosened it slightly. Attach the wheel and engage the handbrake to the fourth click, then manually rotate the wheel. I modified it till the fourth click secured the wheel, rendering it immovable by hand. This caused the brake shoes to excessively contact the rotors, inhibiting rotation by more than 25% of a full turn. It felt inappropriate, so I adjusted it more. The wheel operates more efficiently with a degree of resistance. However, the brake will not secure the wheel until the seventh click.
