What is a jake brake?
A jake brake or engine brake is a system used in diesel engines to slow the vehicle down without the need to use the traditional braking system. This system works by releasing compressed air from the engine’s cylinders to slow down the engine’s momentum, which in turn slows down the vehicle. The system is named after its inventor, Clessie Cummins, who developed the system while working for the Cummins Engine Company in the 1950s.
Jake brakes are not a separate braking system but are rather an additional tool that truck drivers can use to slow down their vehicles. They are most commonly used in long-haul trucks, buses, and other large commercial vehicles. Because these vehicles use air brakes, which can overheat and fail if overused, jake brakes are a valuable tool to have.
Jake brakes are often confused with compression release brakes, which work in a similar way but use the engine’s compression to slow the vehicle. However, despite the similarities, there are some differences in how the two systems operate.
How does a jake brake work?
A jake brake, also known as an engine brake, is a mechanism installed in diesel engines to assist in deceleration without the use of conventional brakes. It is commonly used in heavy vehicles such as trucks and buses, but can also be found in some smaller diesel vehicles and recreational vehicles. A jake brake uses the compression of the engine to slow down the vehicle, which reduces wear and tear on the braking system and can also increase safety by providing additional control in certain situations.
- The jake brake is activated by either flipping a switch or releasing the throttle while the engine is under load.
- When the jake brake is engaged, an actuator opens the exhaust valve on the engine in a manner that interrupts the compression stroke and releases pressure in the cylinders.
- This release of pressure produces resistance against the motion of the engine, which in turn slows down the vehicle.
It is important to note that a jake brake should only be used under appropriate conditions, and can be less effective in cold or wet weather. Additionally, excessive use of a jake brake can produce excessive noise levels, leading to noise pollution in urban areas.
In summary, a jake brake is a useful tool for heavy-duty vehicles to assist in deceleration and reduce wear on the braking system. By utilizing the natural compression of the engine, the jake brake provides additional control and can be an effective safety tool when used properly.

Why is a Jake Brake used?
A Jake brake, sometimes referred to as Jacobs brake, engine brake, or compression brake, is a mechanism added to the internal combustion engine of a vehicle that enables drivers to slow down their vehicles without using the service brakes.
There are several reasons why a Jake brake is used, some of which include:
- To reduce wear and tear on the service brakes: Continuous use of the service brakes can cause them to overheat and wear out quickly. Employing the Jake brake reduces the amount of work the service brakes have to do, which can extend their lifespan.
- To prevent brake fade: During prolonged brake application, the friction between the brake pad and rotor can cause the pad to overheat, resulting in reduced braking performance or brake fade. Using the Jake brake reduces the temperature and friction on the brake components, decreasing the likelihood of brake fade.
- To increase safety: The Jake brake helps to slow down a vehicle in a controlled and efficient manner. It is particularly useful when driving downhill or in poor road conditions, such as snow or rain, as it reduces the likelihood of skidding or losing control of the vehicle.
When a vehicle is descending a steep downhill slope, the Jake brake can be engaged, increasing the backpressure in the engine, reducing the speed of the vehicle. However, it is essential to note that using the Jake brake when driving on a snowy or icy road requires caution.
Snow and ice can make roads slippery, and when a driver applies the Jake brake at high speeds, it can cause the vehicle’s wheels to lock, leading to a loss of control. As such, drivers should only use the Jake brake as needed and adjust their speed accordingly to avoid any potential mishaps.
| Pros | Cons |
|---|---|
| Reduces wear and tear on the service brakes | Can be noisy, leading to noise pollution |
| Increases safety when driving downhill or in poor road conditions | Can cause engine damage if not used properly |
