retarder
Brake assist mechanism
A retarder is something that slows or delays a process.
In vehicles, a retarder is a braking device that reduces speed without using the main brakes—common on trucks and buses descending long grades.
In construction, a retarder is an additive that slows the setting of concrete or plaster, giving workers more time: Add retarder to the mix in hot weather.
