The amount of "drag" the engine's compression provides when freewheeling--ususally down hill. It's not too valid a measurement when an automatic transmission is part of the drive chain.

Brake horsepower indicates that the engine's power was measured on a device called a brake dyno. A brake dyno has the engine spin a shaft attached to a brake. The dyno operator adjusts the brake to hold the engine steady at a particular RPM and records the forces acting on the brake, then moves on to another RPM so as to get a map of the engine's performance throughout its RPM range. Then the measurements can be used to calculate the engine's horsepower and torque.
There are other ways to measure horsepower, such as an inertial dyno. This one has the engine (or the car's drive wheels) spin a heavy drum or flywheel, with horsepower calculated from how fast the wheel spins up.

Brake Hp is the power developed by the engine minus the loss in power due to friction from the power train itself. it's the power available at the wheels.
So if an engine develpos 200 HP, the BHP may only be 175 due to frictional losses.

Should be same as horse power that boost your car...but the horse pulling back the car.....

its Brake horsepower, and its hp measured at the flywheel, so it doesnt encurr any of the drivetrain losses. For instance a car with 85 WHP has around 100 Bhp. the 15 hp lost is in the drivetrain/tranny.

engine break, use of engine to stop the car by shifting to lower gear
