INTRODUCTION

This is to focus on the emerging IOT service associated with smart maintenance for a four wheeler vehicle by detecting the defect at its initial stage and informing about it to the owner of the vehicle. Here, we are targeting to maintain the brake system by monitoring the brake shoe pad thickness, brake oil leakage and other defects in the brake system can be detected by setting up some threshold values for force and speed.
