What is an exhaust brake?

An exhaust brake is a type of braking system used in diesel engines to assist in slowing down the vehicle. It works by creating back pressure in the engine's exhaust system, which in turn restricts the flow of exhaust gases and helps to slow down the engine and vehicle.

Exhaust brakes are typically controlled electronically and can be engaged or disengaged by the driver as needed. They are often used in large trucks, RVs, and other heavy-duty vehicles to help reduce wear and tear on the vehicle's traditional brake system, as well as to improve overall braking performance and control.

One of the main benefits of an exhaust brake is its ability to provide additional braking power when driving downhill or towing heavy loads, which can help to reduce brake fade and overheating. However, exhaust brakes may also produce increased noise and emissions, so they are not suitable for all vehicles or driving conditions.

Overall, an exhaust brake can be a valuable addition to a vehicle's braking system, especially for those who frequently tow heavy loads or drive in mountainous terrain.
