What are the three braking methods of motor vehicles?

[MacElliot]

Motor vehicles have three braking methods: service brake, parking brake, and engine brake. Below are the specific introductions about motor vehicle braking: 1. Service Brake: The service brake is commonly known as the "foot brake." It is the braking method used during normal driving. It primarily converts the mechanical force from the brake pedal into hydraulic pressure, which is then transmitted to the brakes and applied to the vehicle's four tires to achieve the braking effect. 2. Parking Brake: The parking brake is commonly known as the "hand brake." It is used when the vehicle is parked to prevent the vehicle from sliding. The main working principle involves connecting a steel wire cable to the brake shoes to apply braking force, typically acting on the vehicle's rear wheels. 3. Engine Brake: Compared to the service brake and parking brake, the engine brake is somewhat more unique. It primarily utilizes the compression resistance, exhaust resistance, and internal friction generated by the engine to brake the drive wheels. It is generally used in special environments, such as muddy roads and icy or snowy conditions.
