What is the Braking System Composed of?
2 Answers
The braking system is composed of the brake transmission device and the brake. The brake transmission device includes the energy supply device, control device, and transmission device, which consists of various components and pipelines that transmit braking energy to the brake, such as the brake pedal, master cylinder, wheel cylinder, and connecting pipelines. The brake is the component that generates the force to resist vehicle movement or the tendency of movement, achieved through the friction between the fixed element and the rotating element's working surface. The main functions of the braking system are to decelerate or even stop a moving vehicle, maintain a stable speed for a vehicle going downhill, and keep a stationary vehicle from moving. Based on the transmission of braking energy, braking systems can be categorized into mechanical, hydraulic, pneumatic, electromagnetic, and combined types.
The automotive braking system is far from simple, with its core components consisting mainly of brake discs, brake pads, and calipers. The brake disc is fixed to the wheel and rotates with it, while the brake pads are housed within the caliper and rely on friction to slow down the vehicle. When the pedal is pressed, brake fluid pushes the piston through the hydraulic system, causing the pads to clamp onto the disc, with the vacuum booster assisting to reduce pedal effort. Don't forget the ABS sensors and controller, which monitor wheel speed to prevent lock-up, along with the master cylinder managing hydraulic pressure and the wheel cylinders distributing it to each wheel. The connecting pipes link all parts, and the brake fluid must remain clean and heat-resistant to avoid affecting responsiveness. Only through the coordinated operation of these components can safe stopping be achieved. I prefer to regularly check pad thickness and fluid levels, as unusual noises or vibrations serve as warnings that repairs are needed. The joy of driving is built upon reliable braking—failure to maintain it can lead to severe consequences, such as rear-end collisions due to emergency brake failure. Don't skimp on daily maintenance; pad replacement intervals depend on driving habits, with more frequent changes needed for those who drive at high speeds often.
