The role of copper (Cu) in modern brake disc pads is essential due to its contribution to heat transfer and dissipation during braking while reinforcing the thermal resistance over time. It also strongly contributes to the performance in terms of noise, vibration and harshness (in short NVH) due to its lubrication properties. Since 2010, when the states of Washington and …

The compressibility of brake pads consists of measuring the thickness change in μm under a defined uniaxial pressure or how much a brake pad can be pressed together.  Pad compressibility can be an important design parameter of braking systems, which significantly impacts brake performance, comfort, and behavior that the driver experiences, as well as noise and vibration development.  Among ingredients …
