Why is it important to bed in new brake pads?

Bedding in new brake pads is essential because it establishes a proper contact surface between the brake pads and the rotors. This process helps to create an even layer of brake material on the rotor, allowing for optimal friction when the brakes are applied. Proper bedding ensures that the pads perform effectively right from the start, resulting in better braking performance, reduced stopping distances, and improved safety. Additionally, when brake pads are bedded correctly, it can lead to a longer lifespan for both the pads and the rotors, as it minimizes uneven wear and potential damage that can occur when pads are not properly seated.

The other options do not directly relate to the primary purpose of bedding new brake pads. While reducing noise may be an indirect benefit after proper bedding, it is not the primary reason for the procedure. Similarly, improving appearance or increasing vehicle weight have no relevance to brake efficiency or performance.
