“…One of the materials that was often used in brake pads before is asbestos, which has excellent mechanical and tribological characteristics that are needed to meet the friction characteristics. 73 Today, asbestos is not used in brake pads, bearing in mind that it has been established that asbestos and the resulting particles can have a significant negative impact on human health. 74,75 According to Hulskotte et al, 27 the composition of 65 commercial brake pads was tested and determined that the dominant metals in brake pads are Fe, Cu, Zn and Sn; on the other hand, the dominant metal in the discs is Fe.…”

The braking system is one of the important systems from the aspect of vehicle safety, but it is also one of the systems that has a significant impact on the environment. Brakes are considered to be a source of non-exhaust particles, that is sources that create particles by the wear of the elements that are in contact with each other, and in this case, the brake friction elements (brake pads and rotating disc). Such particles often contain heavy metals that are part of the friction elements. There are a number of influencing factors that can affect the wear of the friction elements and increase the concentration of the formed particles. Laboratory methods of testing wear and particle formation, road tests and various simulations of brake wear are most often used for testing. In this paper, a review of methodologies for testing the formation of particles from the braking system, the materials used in the composition of the friction elements of the brake, as well as factors affecting the wear rate and concentration of particles of different sizes, based on the conclusions of other authors is presented. Based on this review, it can be concluded which quantities and factors need special attention during further research in the mechanism of formation of non-exhaust particles whose source is the vehicle braking system.

“…The tight link between exposure to asbestos and pulmonary disease was not well known until the mid-1970s. People who have worked on asbestos-inclusion friction materials and workers or supervisors working in the vicinity could have inhaled asbestos fibers while carrying out their duty so placing them in danger of contracting different infections like pericardial mesothelioma, pleural, peritoneal, or cancer of asbestosis (Cueva G. el ta [8], Ahmad Kholil el ta [9], Abutu J [10], Shinde, D [11], and Krishnan el ta [12]).…”

Coconut Fruit Fiber, CFF, and Oyster Sea Shells, OSS were gathered from the waste peel and suspended in a solution of sodium hydroxide (NaOH) for about 12h in other to eliminate unwanted remnants. Dried CFF and OSS were grounded to powder using an electric grounding machine. Thereafter sieved to 75, 125, and 175µm grain sizes. The based materials, CFF and OSS were prepared into organic-based brake pads by compressive molding with different formulations of base materials, epoxy resin, hardener, graphite friction modifiers, and copper chips. A commercially bought brake pad was used for evaluation in this research. The characterization of the brake pad produced is mostly influenced by molding pressure and grain sizes, respectively. Hence, the density, hardness, tensile strength, and compressive strength values were reduced with a rise in grain sizes. In conclusion, the ideal values of all responses fall within the normal desires of brake pads as they matched positively with commercial lining material. Thus, the characterization of the developed friction lining links suitably and is proficient in creating fewer sounds during the application of braking, owing to its high mechanical properties. Therefore, coconut fruit fibers and oyster sea shells can be a conceivable replacement for asbestos friction brake lining manufacture.

“…The development of composite materials is one of the most important advances in the history of materials and is related to the field of manufacturing technologies [3]. Composite materials use non-asbestos as a comparison with asbestos brake pads and hereafter composite materials can replace the asbestos in brake pad materials [4]. The production of brake pads from composite materials is currently being developed and researched.…”

The utilization of Aegle marmelos shell particles is not optimal yet. Composite brake pads are currently being developed because they are eco-friendly and heat resistant compared to non-asbestos brake pads. This research attempt to analyze the volume fraction of Aegle marmelos shell particles on the measure of hardness, toughness, and wear of epoxy matrix composites as an alternative material for motorcycle brake pads. The design of this research uses a true experimental design with a posttest-only design type, there is an experimental group (composite) and a control group (Indoparts brand brake pads). The results show the most optimal measure is found in volume 30% with a hardness measure of 79.5 HRB, toughness 0.01312 J/mm2, wear 2.008 x 10-6 mm2/kg. It shows that the more particles volume, the composite strength will increase. This measure is closest to the measure of the Indoparts motorcycle brake pads. Therefore, Aegle marmelos shell particles composite can be recommended as an alternative material for motorcycle brake pads.
