What is the Service Brake System?
3 Answers
Service brake system refers to a series of specialized devices that can forcibly reduce the vehicle's traveling speed. Below is relevant information: 1. Engine: Crank-connecting rod mechanism, valve train, fuel supply system, ignition system, lubrication system, cooling system and starting system. 2. Chassis: Transmission system, running gear, steering system and brake system. The transmission system transmits engine power to the driving wheels, consisting of assemblies such as clutch, transmission, universal joint drive device, and final reducer. The running gear consists of frame, steering axle, drive axle, suspension, wheels, etc. The steering system consists of steering gear and steering linkage. The brake system generally consists of two independent sets of devices, namely the service brake system and parking brake system. 3. Body and electrical equipment: The body is used to accommodate the driver, passengers and cargo. The electrical system consists of power supply, ignition system, starting system as well as vehicle lighting system, signal system and instruments.
As an ordinary person who drives frequently, I believe the service brake system is the main component you use to stop the car while driving. It includes parts like the brake pedal, brake fluid, master cylinder, calipers, and brake discs. When you press the brake pedal, it compresses the brake fluid, transferring force to the wheels and slowing the car through friction. I once experienced severely worn brake pads and almost rear-ended another car, which made me pay extra attention to maintenance ever since. If not properly maintained—like having a brake fluid leak or worn brake discs—the car won’t stop effectively, which is especially dangerous on highways. So, I recommend doing a simple check every month: listen for unusual noises, feel if the brakes are too stiff, and address any issues immediately. Regular maintenance, such as changing the brake fluid every two years, can save you from major trouble.
As someone with some knowledge about cars, I'd say the service brake system is essentially a deceleration mechanism operated by hydraulic or air pressure. When you press the brake pedal, the master cylinder compresses the brake fluid, pushing the calipers to clamp the disc or drum brakes, creating friction to stop the vehicle. Modern cars also feature ABS systems to prevent wheel lock-up during skidding, enhancing safety. I enjoy studying these systems and find their design quite ingenious—the entire chain from pedal to wheel must function reliably. In daily use, if the system fails—say, due to a leaking hose or faulty sensor—the brakes may feel spongy or fail entirely, increasing accident risks. I recommend drivers get professional inspections regularly rather than relying solely on personal judgment, especially for older vehicles where hydraulic fluid levels need attention.
