DESCRIPTION
An exhaust brake is a device that assists in slowing down a truck by restricting the exhaust flow from the engine. The 4089339 model is a specific type of exhaust brake designed for use with heavy-duty trucks. When activated, this brake creates back pressure in the engine that helps to reduce the speed of the vehicle without relying solely on traditional braking systems. This can be especially useful when driving downhill or carrying heavy loads, as it can help to reduce wear and tear on other components and improve overall safety.
