A review of the Composition, Process, Materials and Properties of Brake Pad Production

Abstract

This is a review and overview of the trending researches in automobile brake pad production processes, formulations, materials, and properties. Most of the works attempt mainly on replacing asbestos found to be carcinogenic with base materials with other ingredients in various formulations and particle sizes. Though most of the replacements are non-hazardous with properties such mechanical and tribological characterizations comparing well with the traditional asbestos based brake pad. The overview of these trends suggests the need to replace not only the asbestos but also the commonly used epoxy resins or phenolic resins or phenol formaldehyde binders that has been found to corrode outside plates of brake assembly. These reviews has thrust a new research direction of replacing the asbestos and inorganic resins with agro based materials of Cashew Nut Shell and Plant Gum binder respectively to obtain a substantially green based brake pads that are non-injurious to human health and does not corrode any parts of the brake pads assembly
