What are the consequences of continuous use of the service brake?

[AliyahLee]

Continuous use of the service brake on long downhill slopes can cause the brake temperature to rise, leading to a sharp decline in braking effectiveness. This can result in overheating of the brake pads, thereby reducing braking force. In severe cases, it may even lead to a complete loss of braking ability, causing brake failure. Therefore, when descending long slopes, it is advisable to use a low gear and employ engine braking. Relevant information about braking is as follows: 1. Introduction: Refers to the action of stopping or reducing the speed of running locomotives, vehicles, other transportation tools, or machinery. 2. Principle: The general principle of braking involves fixing a wheel or disc on the high-speed shaft of the machine and installing corresponding brake shoes, bands, or discs on the machine base, which generate braking torque under external force.
