Nowadays accidents might occur because of varied reasons; the foremost reason is equipment failure and is happened due to improper maintenance of the products. To prevent these abnormal situations and to protect one's life from these accidents, there's a necessity for watching of braking system in cars. Special safety options are engineered into vehicles occupants solely, and a few for the security of others. [1].

Brake failure is one of the leading causes of road accidents. Despite of the presence of primary braking systems like disc (operated via Hydraulic or pneumatic system) or drum brakes, a sudden loss of braking function can lead to disastrous consequences. To address this issue, we propose a Lever-Activated Ground Drag Emergency Braking System a purely mechanical bias system, secondary braking mechanism designed to provide immediate deceleration in the presence of primary brake failure.

This system operates independently of the existing brake setup and consists of a manually operated lever connected to a ground-facing friction plate. When @peated, the friction plate is deployed against the road surface, utilizing drag to slow the vehicle safely. The mechanism includes a pivot arm, linkage rod, and return spring, making it simple, reliable, and effective. It does not rely on any electronics or hydraulics, ensuring functionality even under complete system failure conditions.

The design is low-cost, lightweight, and suitable for retrofitting into various vehicles, particularly in rural or rugged terrains. Through technical calculations, CAD modelling, and mechanical analysis, this project demonstrates the feasibility and effectiveness of the proposed system. The ultimate goal is to offer an additional layer of vehicle safety, especially for scenarios where electronic solutions may not be viable. Brake failure continues to be one of the most common causes of road accidents, particularly in modern vehicles which are fully automatic sensor based which have even given up the traditional hand lever mechanical parking brakes, instead using Electric parking brakes. This project proposes a simple, cost-effective, and purely mechanical emergency braking system that can be activated manually via a lever. The system utilizes a ground drag friction plate to decelerate the vehicle when the primary brake fails.

In the rapidly evolving landscape of automotive safety, one persistent and often overlooked challenge is brake failure. Despite advancements in anti-lock braking systems (ABS), electronic stability control (ESC), and hydraulic braking systems. The failure of a primary braking system due to fluid leakage, wear and tear, overheating, or mechanical damage can have catastrophic consequences, especially when it occurs at high speeds or in congested traffic conditions.

Currently, the standard solution for emergency braking includes ABS Braking system or electronic backup systems. However, these have their limitations.

This project addresses that gap by developing a Lever-Operated Ground Drag Emergency Braking System a fail-safe, secondary brake that uses friction against the road surface to slow down the vehicle. The system is operated via a simple hand lever connected to a ground-facing friction plate through a linkage and pivot mechanism. When engaged, the plate is lowered onto the road, creating drag force and assisting in decelerating.
