| When your car cruises down the road at top | | | | does the heat get released? Well the brake pads |

| energy is so much that unless it is reduced in a | | | | all the brake pad must rub against something to |

| test video you will have some idea of the | | | | And it is the brake rotors that have a feature |
| immense amount of energy that a moving car | | | | that allows the heat to escape. This feature is |

| when you apply the brakes where does all that | | | | gases and even water can escape when the |

| even get a scratch leave alone getting smashed | | | | The drilled brake rotors have holes to allow the |

| The answer is that the energy gets released as | | | | have slots to allow the heat to escape. The drilled |
| heat in the braking components of your car. And | | | | brake rotors have lesser surface area but are |
| you can imagine that a lot of heat will be created | | | | adequate for everyday driving. Slotted brake |
