If you are a truck driver, you understand the importance of safety on the road. One of the safety features that is often overlooked is the Jake Brake or engine retarder. The Jake Brake is a compression release engine brake that is designed to slow down your truck and reduce wear and tear on your brakes. In this article, we will discuss everything you need to know about the Jake Brake switch wiring diagram.
What is a Jake Brake?
A Jake Brake is an engine brake that is used in diesel engines to slow down a vehicle. It works by opening the exhaust valves in the engine to release compressed air. This creates a braking effect that slows down the vehicle, reducing the need for the brakes. The Jake Brake is named after its inventor, Clessie Cummins, who created it in the early 1960s.
The Jake Brake is primarily used on large commercial vehicles, such as trucks and buses, to help reduce the wear and tear on the vehicle’s brake system. It also improves driver safety by allowing the driver to slow down the vehicle more quickly in emergency situations.
