| dc.description.abstract | Brakes and tires are the major contributors for catastrophic failure of ground vehicles. Braking
system is the utmost important besides tire to ensure the safety of users and vehicle. Ensuring good condition of brake lining is very crucial to ensure the efficiency of the braking
system, where, the worn off brake lining not only endangers life but also damages the entire
brake associated parts such as hub, disk, shaft, etc. It consists of a sensor. One sensor is
connected with the brake shoe. The signal from the sensor is given to a micro-controller. When the brake shoe is worn out, the sensor senses signal to the micro-controller. The
micro-controller analyses the signal and operates the corresponding indicator. Brake pad
worn out detection sensor is mounted in the brake pad and it is connected to the Node MCU. Therefore, a critical investigation of the existing pads manufactured and their
characterizations are conducted to identify the most suitable sensor spot on the brake pad. Later, a micro sensor is embedded into the pad and fully tested on a specially designed test rig. The evaluation of thickness, hardness, layer properties and critical wear region has enabled
the spotting of exact sensor location. The embedment of the micro switch was successfully
done and tested to be very efficient in alerting the driver upon reaching the maximum lining
wear limit. Finally, when the brake pad is fully wasted then the system provides a signal the
