“…Now some tribological aspects of disc-pad systems which are peculiar to disc brakes will be described. This description is mostly based on the previously published works [45,63,17,38,56,37,67]. In these works friction materials of different compositions were used so some of the phenomenon described here could not be valid for all other materials as also explicitly mentioned in [17,67].…”

Disc brakes have evolved over time to be a reliable method of decelerating and stopping a vehicle. There have been different designs of disc brake systems for different applications. This review gives a detailed description of different geometries of the components and the materials used in a disc brake system. In spite of all the improvements, there are still many operational issues related to disc brakes that need to be understood in a greater detail and resolved. There has been a lot of research going on about these issues and at the same time different methods are being proposed to eliminate or reduce them. There has also been an intensive fundamental research going on about the evolution of tribological interface of disc-pad system. One major purpose of the present paper is to give a comprehensive overview of all such developments.

“…Identification of material behavior model shows that the heterogeneity is very strong at different friction states with a global decrease of the equivalent bulk Young Modulus depending on the history effect. This history effect has an impact on the roughness too which changes the local stiffness as shown by [13]. A complete model considering the floating caliper and vented disc as in real test application, coupled with data acquired with indentation have been studied in a complex eigenvalue analysis.…”

“…There is almost any real complete multi-scale approach from the system to the contact interface. These are mostly simple approaches and only a few finite elements approaches except for example Heussaff work [13], which is only focused on the surface interface. The goal would be to take also into account the near-contact volumic 2 properties including surface and material heterogeneous properties.…”

Friction pads are made by a recipe of numerous components leading to a heterogeneous material. The originality of this paper is firstly to propose a method leading to identify local mechanical properties of friction a pad, performed at different locations, via an indentation test. Secondly, the mechanical properties obtained for each location are introduced in a modeling to perform a complex modal analysis. A comparison with an equivalent homogeneous friction pad is performed to highlight the difference. Finally, the previous approach is extended to other friction pads which have been submitted to the same test sequence but interrupted at different times to investigate the history effect.

“…The second one usually occurs in the frequency range between 1 and 16 kHz. Some studies showed the importance of the disc topography in the generation of automotive disc brake vibrations (Heussaff et al, 2012;Yoon et al, 2012). Some commonly used techniques to reduce noise and squeal, and solve other important problems during the braking process can be shot-blasting (Bergman et al, 1999) and grit-blasting (Hammerström and Jacobson, 2006).…”

Nowadays, brake disc manufacturers are seeking new finishing techniques to offer economical solutions to their customers and so become more competitive. The elimination of the surface spiral pattern after turning operation is a challenge to avoid braking problems at the early life of the component. This paper presents a practical low-cost solution to finishing this kind of component. Concretely, a detailed study of the brushing process as an alternative solution to the conventional grinding process is performed. The limited literature regarding this topic implies the necessity of a full study of the process prior to any industrial application. The influence of process variables on the final surface was analyzed in this work. In addition, the tool wear and tool life behavior, the influence of the abrasive type used and the originating forces during the process were taking into account. Once the process was established, various prototypes were finished in order to check the feasibility of the process and to pass the required quality control. Results show that brushing is a feasible and economical alternative for brake disc finishing. The surface quality obtained was shown to be equal or better than grinding, with reduced costs and manufacturing time.
