What Parts Does the Braking System Include?
2 Answers
The braking system consists of four parts: the energy supply device, the control device, the transmission device, and the brake. 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. To ensure safe driving, improve the average driving speed, and enhance transportation productivity, all vehicles are equipped with a dedicated braking mechanism, known as the braking system. The working principle of the braking system involves using friction between non-rotating components connected to the vehicle body or frame and rotating components connected to the wheels or drive shaft to prevent the wheels from turning or their tendency to rotate.
Having driven for so many years, I'm very familiar with the braking system—it's the lifeline of driving safety. Key components include the brake pedal, which you press to activate the entire system; the master cylinder, which converts force into brake fluid pressure; the booster, making it easier to press the brake; the brake lines, consisting of flexible hoses and rigid pipes, transporting fluid to the wheels; and the wheel-end components. For disc brakes, there's the caliper assembly that clamps the brake disc and friction pads, with the disc friction creating deceleration. For drum brakes, it includes the wheel cylinder pushing the brake shoes against the drum. Don’t forget the brake fluid, which must be replaced every two to three years—aging and water contamination can reduce effectiveness. I often check the brake fluid color and water content; if it turns black, it's time to replace it. When the brake pads wear thin, they squeak, signaling it's time for new ones. Ignoring these can lead to soft or ineffective brakes in emergencies, greatly increasing risks. That’s why I’ve made it a habit to glance monthly for any leaks or abnormal wear.
