There’s also a thing called a retarder built into lorries and other heavy vehicles so they don’t melt their brake pads, think engine breaking as the basic version, add special engineering sauce and you get something that is good at slowing stuff down without burning up, but not good at all at arresting it in place. The term is also used with railroads but those are actual breaks. Similar to the ones you see on roller-coasters.
