What is the primary purpose of breaking in new disc pads?

The primary purpose of breaking in new disc pads, often referred to as bedding or curing, is to condition the pads and rotors. This process involves using controlled braking to establish a proper interface between the brake pads and the rotors. During the break-in period, the pads transfer a layer of material to the rotor surface, enhancing friction and ensuring optimal braking performance.

This conditioning is crucial because it helps to eliminate any inconsistencies in the surface of the pads and rotors. As they adhere to each other through this process, the pads achieve their intended friction characteristics, which can significantly affect the effectiveness and responsiveness of the braking system. This proper contact also reduces the likelihood of issues like brake fade or uneven wear over time.

While the other options touch on relevant brake system concepts, they do not encompass the main goal of the break-in process as effectively as conditioning the pads and rotors does.
