In Modern Passenger Car Braking system, Disc brake plays a vital role in providing better performance and safety, in which brake pads are most critical part to decide the overall brake performance. In such brake pads, there are some technical challenges such as wear rate, abnormal noise & environmental issues with existing asbestos material. Hence we made a research to furnish suitable eco-friendly & cost effective solution. The main objective of this paper is to introduce asbestos-free automotive organic brake pad. Our research work intends to make organic brake pad by using natural fibre with organic ingredients such as kenaf and other composite materials in right proportion. Kenaf fibre is one of the natural fibres, which will improve heat resistance and strength of the brake pad. Initially, kenaf fibre is mixed with other composite materials and compacted at an optimal pressure by using hand-press machine.

Electro-Hydraulic Power Steering (EHPS) system is used in modern vehicles to effect reduction in fuel consumption rate and steering effort. The mechanical linkages between the steering wheel and tire, transfers road shocks to steering wheel as high amplitude vibration. This high amplitude vibration causes the steering wheel to deviate from driver intended position. This phenomenon is called steering kickback. The initial objective is to reduce the steering kickback with minimum changes in the vehicle systems. Using check valve is one of the inexpensive and easy operational counter measures. Vehicle level tests were done to evaluate the countermeasure and it was found to have approximately 55 % reduction in kickback. Multi Body Dynamics (MBD) simulation is done using ADAMS/Car to establish the vehicle parameters involve in steering kickback. Full car model was simulated using the experimental conditions and validated.
