Braking Horsepower: How Much Does Your Car Have? Fresno CA

At the most basic level, a brake is an energy conversion device. Normally people will equate temperature with speed. While this is generally true, it is more accurate to associate heat with energy. Today's cars are filled with energy conversion devices. Read on to know more about brakes.

Braking Horsepower: How Much Does Your Car Have?

We all know brakes get hot, sometimes very hot. If you watch closely on race day, it's not uncommon to see the rotor on a race car glowing bright orange. Iron is in the range of 1,700º F when orange.



At the most basic level, a brake is an energy conversion device. Normally people will equate temperature with speed. While this is generally true, it is more accurate to associate heat with energy. Today's cars are filled with energy conversion devices.

Virtually all of the things a car does results from the chemical energy of the fuel or the battery being converted into some useful and desirable function for the driver and passenger. The engine, brakes, heater and radio are a few examples.

The job of the brakes is to convert the energy of a moving vehicle into heat resulting in the vehicle reducing speed.

Stopping with Horsepower
One of the basic physical laws of the universe is that all energy is conserved. In simple terms, energy can't vanish. It can change forms, perhaps multiple times, but it is always somewhere. The engine, through the combustion process, converts the chemical energy of the fuel into heat that moved pistons to accelerate a vehicle to some speed or altitude. We rely on the brakes to stop us, now.

Consider a typical midsize SUV loaded to its gross vehicle weight of approximately 6,400 lbs. While traveling at 60 mph, it has a "kinetic" energy equal to 988 British Thermal Units or BTUs. This is calculated according to the equation for ener...
