Correct answer
- BCuando no lleva carga frena mejor.It brakes better when it is not loaded.
Going downhill, a vehicle brakes better when it is not loaded. This is because a loaded vehicle has more mass, which increases inertia, so it needs more distance and more braking effort to stop. The load also increases the pressure and temperature in the braking system, which can reduce its effectiveness, especially on long descents. On the other hand, when the vehicle is not loaded, it weighs less, has less inertia and the brakes work more effectively, allowing safer, more controlled braking.
