Abstract
Brake linings have complex microstructure and consists of different components. The purpose of this research is to optimize the use of brake liner frictional materials with new formulation incorporating micaceous iron oxide and calcium carbonate as a filler material and comparison of improvement in frictional value with other filler materials. This new formulation was tested under various operating conditions with a chase machine friction testing rig. The friction test rig was programmed with different test loops to perform test as per SAE J661. The average coefficient of friction, coefficient of friction with changing speed, temperature and load, thickness loss and weight loss were accounted. Formulation exhibits better thermal stability and wear resistance to the latter.
