Abstract
One of the failure factors in braking is the loss of the ability of brake lining material to the braking process. The quality of brake lining depends on several factors, namely the composition of the material, type of material and hardness. Brake pads is one component in the braking system that is directly in contact or rubbing against the rotating part in this case the drum (drum system) or disk (disc system). The ability of brake pads has an important role, namely to absorb the amount of kinetic energy during braking. In general, brake pads are made of asbestos material because they are superior in temperature resistance up to 800˚C, but asbestos materials have carcinogenic properties that have a negative impact on the environment and human health. This research was developed to answer these problems, namely to look for alternative brake pads that have good toughness and structural properties and do not interfere with the health of the vehicle driver or are environmentally friendly. Brake pad materials are made from hybrid composites reinforced with basalt, shellfish, alumina and bound using phenolic resin polymer (PR-51510i). This brake pad materials is produced through a sintering process with an emphasis of 2000 kg for 30 minutes at a fixed temperature of 150 °C. This composite was made as many as five variations, each of which tested its strength using the charpy impact test according to ASTM D 6110 standard. The strength of the average brake pad specimens obtained was 0,0003327 J/mm², better than the average toughness of brake linings from asbestos ingredients
