Research shows that there is an increasing interest in alternative friction materials that do not harm human health and the environment, especially after the harmful effects of asbestos were revealed and its use was banned. This study evaluates the potential of apricot kernel shell, an agricultural waste, to be used as a bio-material in brake pad compositions.
Ingredients in Brake Friction Material. There are more than 200 ingredients used to produce commercial brake friction materials; the typical ones are listed in Table 1.Their tribological properties are affected by size, shape, and chemical composition, and details about the ingredients are normally considered proprietary information, along with the formulation of .Automotive and truck brake shoe materials are complex composites of metals, ceramics, and polymers. These are designed to provide stable, reliable frictional performance over a range of vehicle operating conditions, exhibit acceptable wear life, and offer freedom from noise and sensible vibrations.

Fillers - They are added to the friction material composition of brake pads to improve their manufacturability and lower the total cost of production [7]. Inorganic and organic fillers are the two types of fillers available. Barium sulphate (barite or baryte), calcium carbonate, vermiculite, mica, petroleum coke, molybdenum trioxide, and carbon .Brake pads convert the kinetic energy of a vehicle to thermal energy through friction.Two brake pads are contained in the brake with their friction surfaces facing the rotor. [1] When the brakes are hydraulically applied, the caliper clamps or squeezes the two pads together onto the spinning rotor to slow and stop the vehicle. When a brake pad heats up due to contact with the rotor, it .The purpose of this report is to present a survey of commercial brake materials and additives, and to indicate their typical properties and functions, especially as regards their use in heavy trucks.
