What Is a Jake Brake? A How-To Guide for Truck Drivers

If you’re a truck driver, then you’ve probably heard of a Jake brake. But what is it? A Jake brake is a device that helps to slow down a truck. It’s named after its inventor, Jacob Bendix. In this blog post, we will discuss how a Jake brake works and provide a how-to guide for using it! 

How a Jake Brake Works

The Jake brake on trucks is a hydraulic braking system. It uses the engine’s compression to create resistance and slow the truck down. When the brake pedal is pressed, fluid travels from the master cylinder to the slave cylinders, which apply pressure to the pistons. The pistons push against the discs, which creates friction and slows the truck down. 

How to Use a Jake Brake

There are two ways to use a Jake brake: with your foot or with your hand. To use it with your foot, press down on the brake pedal as you would normally. To use it with your hand, squeeze the Jake lever located next to the steering wheel. Experiment with both methods to see which one works best for you. 

When to Use a Jake Brake

There are a few times when it’s appropriate to use a Jake brake: 

  • When descending hills 
  • When driving in mountains or hilly areas 
  • When you need to slow down quickly 

Remember, the Jake brake should only be used as a supplement to your regular brakes. Never rely on the Jake brake alone to stop your truck. If you’re not sure how to use a Jake brake, consult your truck driver’s manual or ask an experienced truck driver for advice.  

Signs of a Problem With Your Jake Brake

If you experience any of the following problems with your Jake brake, stop driving and have it checked out by a mechanic: 

  • The brake pedal feels spongy or soft 
  • The truck doesn’t slow down when the Jake brake is used 
  • There is a loud noise coming from the brakes 
  • Liquid is leaking from the brakes 
  • The brake discs are glowing red 

If you experience any of these problems, stop driving and have your Jake brake checked out by a mechanic. Using a Jake brake when there is a problem can cause serious damage to the brakes. 

Now that you know what a Jake brake is and how to use it, feel free to experiment with it on your next trip! Remember, always consult your truck driver’s manual or ask an experienced truck driver for advice if you’re not sure how to use this braking system.
