Answer:
I won't write your sentences, but I'll give you some help on them.
Explanation:
For a heavy truck, I would use heavy brakes that have much more friction. That way they would be able to stop the trucks momentum.
A lighter truck I would use lighter brakes with less friction. If I had heavy ones and I need to slam on the brakes, they might damage my lighter truck.
A small car would need lighter and smaller brakes than either of the trucks, and I think that you use different brakes for cars and trucks. (not 100% sure)
In a van, I would use a size and weight in between the truck and car sizes and weight. Depending on the van size however, I might use the same ones.
Hope this helps!
