Is a Car with Rear Brake Calipers Considered a Good Car?

[DeBraxton]

Brake calipers positioned at the rear generally offer stronger safety performance. Here are the specific details: 1. Installation Position: In terms of safety and braking performance, calipers installed at the front and rear provide the same braking effect. However, different installation positions can influence the vehicle's dynamic performance. 2. Principle: When a car moves forward, the tires roll forward, and the ground exerts an upward force. For front-wheel brake calipers positioned in front of the disc, during braking, to prevent the tire from continuing to roll forward, the brake disc and caliper generate an upward force together. This force, combined with the ground's reaction force, increases the load on the wheel bearings during emergency braking, amplifying the forward tilting motion of the car's front end—commonly referred to as 'brake dive.' This can more easily lead to a front flip accident. When the caliper is installed behind the disc, the generated force is downward, opposite to the ground's reaction force, which cancels out and reduces the pressure on the wheel bearings, thereby enhancing the vehicle's stability.
