Brake Horsepower

Can someone explain the term "brake horsepower"?

I am familiar with shaft horsepower which is mechanical output of the motor.  Also familiar with fluid power which is the final useful power output of the pump  (volumetric flow-rate time differential pressure).  How does brake HP fit into this picture?

Shaft hp and Brake hp are essentially the same thing.  The term "Brake Horsepower" comes from a type of dynamometer known as a Prony Brake Dynamometer.  This type of dyno uses a mechanical brake with a torque reacting arm of known length that pushes on a scale to measure torque.
