Is braking delayed or advanced when going downhill compared to on flat roads?

[LaSophie]

It is neither delayed nor advanced, but you may feel a decrease and slowdown in braking effectiveness due to gravitational acceleration. Here is some relevant information: 1. Introduction to braking distance: Braking distance is one of the most important indicators used by traffic management departments during vehicle inspections. The 100 km/h braking distance refers to the distance a vehicle travels from the moment the brakes are fully applied at a speed of 100 km/h until it comes to a complete stop with maximum braking force. Currently, there is no specific standard for the optimal braking distance, but generally, a distance within 42 meters is considered excellent, 42-45 meters is acceptable, and anything above 45 meters is considered failing. 2. Factors affecting braking distance: Generally, the more pistons a brake caliper has, the better its braking performance. Additionally, the wear on brake pads and brake discs can significantly impact braking efficiency. The vehicle's load also affects braking distance; in real-life scenarios, the more cargo a vehicle carries, the longer the braking distance tends to be.
