Check on the undercarriage loading, it is nothing to do with the rotor loading. For example, if after take off at 11,600 lbs. you carry out a level 30 degree turn you are loading the rotor to 14,800 lbs. Brakes wont suffer as there is no residual thrust to overcome so braking action can be minimal.
If you are that desperate for fuel monitor the refuelling yourself and call 'Stop' slowly.
