Have you heard a semi-truck make deafening noises when slowing down?
If so, that’s likely the Jake Brake, meaning the driver is using the truck’s engine to slow down.
The noise from a Jake Brake (or Engine Brake) can be terrifying for anyone nearby.
Because they are so loud, some places have banned truck drivers from using engine brakes in certain areas.
Get in touch to uncover the impact our experienced legal team at Tawney, Acosta & Chaparro P.C. can have on your case.
What Is a Jake Brake?
When a truck employs “jake braking,” it utilizes an engine brake for deceleration instead of relying on conventional braking mechanisms.
That’s why you might also hear a Jake Brake called a compression-release engine brake.
Engine brakes produce loud noises due to the quick release of air from cylinders into the muffler, causing resonance and the characteristic loud ‘BRRRR’ when decelerating trucks.
History of the Jake Brake
The invention of the Jake Brake, an essential component for highway safety, is credited to Clessie Lyle Cummins. Cummins, who lived from 1886 to 1968, pioneered this device, which has been manufactured by the Jacobs manufacturing company since 1961.
Fast forward to today, and Jacobs Vehicle Systems has produced more than nine million Jacobs Engine Brakes for commercial vehicles around the globe.
Jake Brake vs. Exhaust Brake
When comparing exhaust brake vs. jake brake, they are both similar but function differently.
An exhaust brake works by creating back pressure in the exhaust system, slowing engine rotation. It traps exhaust gases, causing pistons to push against increased resistance when forcing gases out. This mechanism reduces vehicle speed without relying on traditional brakes.
Exhaust brakes force the motor to rotate slower and are much quieter than Jake Brakes.
How Does Engine Braking Work?
Engine braking in standard petrol engines works by restricting airflow when the accelerator is released, creating a high manifold vacuum that resists cylinder movement. This process reduces energy, resulting in sudden deceleration and a noticeable drop in power.
How Does an Exhaust Brake Work?
An exhaust brake works by creating back pressure in the exhaust system, slowing engine rotation. It traps exhaust gases, causing pistons to push against increased resistance when forcing gases out. This mechanism reduces vehicle speed without relying on traditional brakes.
Jake Brake vs. Engine Brake
A Jake brake, also known as an engine brake, uses the engine’s compression to slow a vehicle down. Specifically, it employs exhaust valves to reduce speed, making it especially effective for trucks. The term “Jake Brake” comes from the company that originally developed this braking system.
Engine Brake vs. exhaust brake
Engine brakes and exhaust brakes both help slow down a vehicle. Engine brakes are effective but noisy, whereas exhaust brakes are silent and more convenient for daily use.
Jake Brake vs Exhaust Brake
An exhaust brake increases engine braking by raising pressure in the exhaust system, while a Jake brake decreases pressure by connecting to the valve train. A Jake brake provides significantly higher braking power than an exhaust brake.
Ban on Jake Brakes
If you’ve ever seen no-engine brake signs, that sign refers to no Jake Brakes.
You’ll likely find bans in residential neighborhoods, near toll roads, or on interstates.
Engine Brakes aren’t necessarily dangerous, but they can be extremely loud. While the noise might not bother some, it can disturb residents, especially early in the morning or late at night.
Engine braking is prohibited in some areas due to its loud noise, especially without a muffler, which resembles a jackhammer and disrupts the surrounding area.
Some towns and cities even fine truckers if they use a Engine Brake within a certain area.
Can Jake Brakes Be Dangerous?
While Engine Brakes are designed to be safe, some situations can make them hazardous. Jake Brakes are great for trucks traveling through mountainous terrain.
However, if a driver doesn’t have experience using an engine Brake or abuses the brake, the truck might not react as expected.
Trucks with Engine Brakes have warnings telling drivers not to use them in slippery conditions. Drivers in trucks with no trailers or very light loads should also avoid using an Engine Brake.
The lack of weight on the tires or a lack of proper traction could result in skidding or a jackknife accident.
Jake Brakes have tremendous stopping power, so drivers must know how to use them properly.
What is a Brake Retarder?
A retarder is an innovative braking system named after the English word “retard,” meaning to slow down. It is commonly used in trucks and buses for additional engine braking.
Why Do They Call It a Jake Brake?
Truckers call it a Jake Brake because Jacobs Vehicle Systems Inc. developed it. This compression release engine brake is also known as a Jacobs Brake or Jake Nett Brake.
Why is Jake Braking Illegal?
Jake Brakes are illegal in some areas due to the loud noise they create when compressed air is released through the exhaust. This noise disrupts residential neighborhoods, leading many cities and towns to prohibit their use near interstates and residential zones.
