Links between brake squeal, third body arrangement and the structure of near surface layers

Puntos clave

• Brake squeal is notably linked to the arrangement of third bodies within near surface layers, complicating brake performance.
• Key evidence shows that variations in third body structures affect the frequency of brake squeal incidents over standard testing conditions.
• The analysis investigates surface layer compositions and friction properties across various brake materials, observing multiple arrangements.
• Implications highlight the potential for improved brake design to reduce squeal, although material interactions remain complex.
