NOTE

BRAKING SYSTEM

A braking system in a vehicle is a mechanism designed to slow down or stop the vehicle's movement by converting kinetic energy into heat energy through friction. It typically consists of components such as brake pads, brake rotors (or drums), calipers, brake lines, and a master cylinder.

Importance of braking system

  1. Brakes are crucial for the safety of passengers, pedestrians, and other road users. They allow drivers to slow down or stop the vehicle to avoid collisions, hazards, or unexpected obstacles.
  2. Brakes provide drivers with control over the speed and movement of the vehicle, enabling them to navigate corners, intersections, and traffic safely.
  3. Proper braking allows for smooth and precise maneuvering, such as parking, reversing, or changing lanes, enhancing the overall handling and agility of the vehicle.
  4. Effective braking contributes to fuel efficiency by minimizing unnecessary acceleration and deceleration, leading to smoother driving and reduced fuel consumption.

What a brake does to a moving vehicle

When a brake is applied to a moving vehicle, it generates friction between the brake pads and the rotating components (brake rotors or drums). This friction converts the vehicle's kinetic energy into heat energy, which dissipates into the surrounding air. As a result, the vehicle slows down or comes to a stop, depending on the amount of braking force applied.
