Brake systems utilize friction to decelerate or stop a vehicle’s rotation. Components include rotors/drums, calipers/wheel cylinders, brake pads/shoes, and hydraulic lines connecting to a master cylinder. Systems employ either hydraulic or electro-mechanical actuation to apply clamping force against rotating components. Modern vehicles increasingly integrate ABS, traction control, and stability control systems utilizing wheel speed sensors and electronic control units. Friction material composition varies based on vehicle type and performance requirements, impacting stopping distance and thermal characteristics. Brake lines and components are engineered to withstand high pressure and temperature fluctuations.
