Engine brake
The engine brake helps slow down the vehicle without using the service brakes. It improves control, reduces brake wear, and enhances safety — especially on long descents.
An engine brake uses the resistance of the engine to assist in slowing the vehicle. Instead of relying solely on the wheel brakes, it allows the driver to decelerate using engine compression or exhaust control — ideal for hilly terrain, heavy loads, or stop-and-go driving.
There are several types of engine braking systems, including compression-release brakes (commonly known as Jake brakes), exhaust brakes, and combination systems with retarders. They’re typically activated via a switch in the cabin and may also work in conjunction with cruise control or automatic braking systems.
By offloading the braking effort from the service brakes, engine brakes reduce heat buildup and wear on the brake components. This extends brake lifespan and provides smoother, safer control — especially when carrying heavy loads or navigating steep terrain.
