DESCRIPTION
An Exhaust Brake is a mechanism that helps to slow down the speed of a truck by restricting the flow of exhaust gases from the engine. It works by creating backpressure in the exhaust system, which in turn slows down the speed of the engine. This type of brake is particularly useful when hauling heavy loads or driving on steep inclines, as it can help to reduce wear and tear on the vehicle's conventional braking system. The Exhaust Brake is typically activated using a switch or button located on the dashboard, which engages a valve that restricts airflow through the exhaust pipe. Part Number 3870840 refers to a specific model or variant of an Exhaust Brake used in some trucks.
