A REVIEW ON DESIGN AND DEVELOPMENT OF COST EFFECTIVE AUTOMATIC AUTOMOBILE BRAKE FAILURE INDICATOR.

Brake failure is one of the major causes of road accidents, often resulting from poor maintenance, improper usage, or manufacturing defects.To enhance vehicle safety and protect human life, continuous monitoring of the braking system is essential.This work presents an intelligent brake failure monitoring and safety system that continuously checks the brake condition during vehicle operation.A sensor mounted on the brake mechanism detects brake wire damage or abnormal brake behavior and sends signals to a microcontroller for analysis.In the event of brake failure, the system immediately activates audio-visual alerts using a buzzer and LED to warn the driver.Simultaneously, an auxiliary secondary braking unit powered by a 12-V battery and disc brake mechanism is activated to slow down and stop the vehicle safely.This system ensures timely warning, effective control, and enhanced passenger safety, thereby significantly reducing accidents caused by brake failure..
