What are the factors affecting braking distance?

Factors affecting braking distance include the friction coefficient of the road surface, the driver's reaction time, and the braking system itself. Below is a related introduction to braking distance: 1. Concept: Braking distance is one of the key parameters to measure a vehicle's braking performance. It refers to the distance the vehicle travels from the moment braking begins until the vehicle comes to a complete stop at a certain speed. 2. Requirements: Braking regulations in various countries stipulate the braking distance for different types of vehicles at specified initial speeds. For passenger vehicles with no more than nine seats, the braking distance should not exceed 19m when the initial speed is 50Km/h. For other vehicles with a total mass not exceeding 4.5t, the braking distance should not exceed 21m at an initial speed of 50Km/h.
After driving for so many years, I've summarized several major factors that affect braking distance. First is speed—the faster the car, the exponentially longer the braking distance becomes; sudden braking at high speeds is especially dangerous. Next is road conditions—rainy or icy surfaces reduce friction, making the car more prone to skidding. Tires are also crucial—worn treads or insufficient tire pressure significantly reduce grip, especially in emergencies where the car can't stop. Additionally, aging brake systems, such as worn brake pads or deteriorated brake fluid, can drastically reduce braking effectiveness. I've also noticed the issue of load—a fully loaded car has greater inertia, naturally extending the braking distance. In daily driving, it's best to develop the habit of anticipating situations, maintaining a safe following distance, and regularly checking tires and brakes, which can greatly reduce risks. On slippery roads, slow down earlier to ensure safety comes first.
