What is the braking principle of a car?
1 Answers
The basic principle of a car's braking system is that when the driver presses the brake pedal, pressure is applied to the brake fluid in the master cylinder. The fluid then transmits this pressure through the pipelines to the pistons in the brake calipers at each wheel. The pistons drive the brake calipers to clamp the brake discs, generating significant friction to slow down the vehicle. The following are the functions of the braking system: 1. Service Brake: During driving, the service brake (foot brake) is commonly used to decelerate the car or bring it to a stop within the shortest distance possible; it also helps maintain a stable speed when driving downhill. 2. Parking Brake: The parking brake not only keeps the car stationary but can also be used in case the service brake fails. Once the car is parked, the parking brake (hand brake) should be applied to prevent the vehicle from sliding forward or rolling backward.
