Helpful Expert Reply:

The nuts on 10" hydraulic brake assemblies, like part # AKUBRK-35R, should be torqued between 45-70 foot lbs.

A torque wrench is recommended to tighten down the nuts to the correct specs. But, if you don't have one on hand, tightening them down until the washer is flat should get you within the recommended torque spec range.
