How braking system work
Of all the systems that make up your car, the brake system might just be the most important. (See diagram below) In the olden days it was also one of the simplest. Over the years as improvements have been made, the system that has evolved isn't so simple anymore... (It's also about a zillion times more reliable and safer.)
Your brakes work as hard or harder than any other part of the car, how much energy it takes to get your car up a hill, it takes at least as much energy to stop it at the bottom. Think about that for a second. Here, I'll say it again, it takes at least as much energy to get your car safely down a hill and stop it at the bottom, as it took to get your car up the hill in the first place. Your brakes do this by converting the kinetic energy to heat energy. All of this heat is generated between the friction surfaces of your brake pads and your rotors. (I am going to disregard the rear brakes for now, since the front brakes do the lion's share of the work.)........ |
