Long-term or prolonged noise sensitivity as well as wear particles such as Particulate Matter 10 (PM10) and Particulate Matter 2.5 (PM2.5) emitted from conventional disc brake system has been attributed to a variety of health issues including stress, reduced concentration, decreased productivity at works, and exhaustion from a lack of sleep, among others. Automobile brakes are widely used in city traffic to control the vehicle. Since the use of automotive brake is frequent, the friction and wear exist between the contact pairs of disc brake may cause unnecessary noise level/wear particles. To tackle this, it was intended to develop the smart braking system and evaluate the significance of noise level and wear emission from the newly developed braking system. A noise measuring unit such as a sound intensity meter or decibel (dB) meter with data recording capability, as well as a wear particle measuring device for measurement of PM2.5 and PM10 particles, were used to investigate the noise and wear emission behavior of the proposed braking system. The numerous trials were conducted thoroughly on the test rig for the wear particle analysis and noise analysis. The findings show that the proposed smart brake blending system is very much efficient to reduce noise emission and wear emission during the braking of a vehicle. The outcome from the present study will help develop the noise-free eco- friendly braking system to enhance the human health aspects related to noise and air pollutions.
