The purpose of an Exhaust Brake System is to give truck owner's SUPERIOR BRAKING CONTROL without relying on the standard axle brakes only. For those who haul heavy loads this is not just convenient and important, but it can be vital for the protection of your very life and those you share the road with.

According to the US Department of Transportation, there are 41,000 truck crashes every year caused by brake failure. That’s 112 every single day here in America alone! You can prevent such a tragedy by installing a Sentinel Exhaust Brake System by Bundy Motors on your truck.

The general concept and design of any Exhaust Brake System is to create exhaust back pressure in the engine. This back pressure creates resistance in the engine and throughout the drive train which slows the truck down without using the standard axle brakes.

The great benefit of an Exhaust Brakes is it allows you to go down long hills safely without overheating your brake or losing control. Without an exhaust brake you have no option but rely completely your axle brakes to slow you down. However, when you use your axle brakes for more than 5 seconds continuously they begin to overheat.

This causes your brakes to overheat, melting the brake pads and the metal surfaces. If this happens to you on a hill in realtime, you could face a complete brake failure. Best case scenario you make it down the hill without a wreck, but your brakes are now compromised and will not work properly to slow or stop you the next time you need them.

After overheating your brakes, the only way to restore full braking capacity again is to perform a complete brake job on your truck. This cycle of overheating and replacing brakes is expenses and unnecessary and can be eliminated when you install a Sentinel Exhaust Brake System™ on your truck.

There are many reason the Sentinel Exhaust Brake System™ is superior to all other systems on the marketplace. Here are just a few:

1. The Sentinel Exhaust Brake System™ creates exceptional exhaust braking power so you don’t have to worry about safe hauling or overheating brakes down hill or coming to a long stop. Many other exhaust brakes on the market are weak and do not create the optimal exhaust bake pressure.

2. The Sentinel Exhaust Brake System™ uses a powerful gear-reduced electric motor that is extremely durable. It does not rely on compressed air or engine vacuum to actuate the brake. No compressors, hoses or fittings are used, making it simple and less prone to fail and will holding up to vibrations or extreme cold and hot weather.

3. The Sentinel Exhaust Brake System™ installs in less than an hour because it is electric actuated and fits on the exhaust pipe. Others exhaust brakes on the market are installed on the turbo or use multiple parts that often fail due to extreme weather conditions (or for just having too many parts) making them complicated. No other system on the market is easier to install and service.

4. The Sentinel Exhaust Brake System™ fits on almost any diesel truck. If it is a diesel and has an exhaust pipe, more than likely one will fit on your truck. Go to our Exhaust Brake Selector to find out if one fits on your truck.

5. The Sentinel Exhaust Brake System™ is warrantied for life. Our Lifetime Warranty is not only the strongest in the industry, it is also the simplest and easiest to understand. There is no fine print. Here is the warranty in full: If your Sentinel Exhaust Brake System fails at any time, for as long as you own it, Bundy Motors will replace it free of charge.

The Sentinel Exhaust Brake System™ is reliable, simple and powerful, built around a gear reduced electric motor that runs off a single controller, has a heavy duty harness, is rust resistant, and just works.! That is why we are leading the exhaust brake industry and can offer a LIFETIME WARRANTY. Oh, and did I mention that when you order a Sentinel Exhaust Brake System™, the shipping is always FREE?

Big Rigs use “Jake Brakes” or engine brakes to reduce speeds when going down hills or coming to long stops . They works by releasing the compressed air in the engine via the exhaust valves to quickly reduce speed, resulting in a loud noise while the engine slows the truck down through the power train.

In practice/theory a Jake Brake and the Sentinel Exhaust Brake System™ do the same thing—they build back pressure in the exhaust creating resistance in the motor so that the the engine itself creates drag on the wheels to slow the truck down without relying on the axle brakes.

However, Jake Brakes are expensive to purchase and require trained technicians to set up and install. Also, they are not manufactured to fit on most medium duty or pick-up diesel truck engines. This creates a problem now that pick-up and medium duty trucks are being built and used to haul heavier loads.

The Sentinel Exhaust Brake System™ is the solution! It easily installs on almost any pick-up or medium duty truck, and builds optimum exhaust back pressure to safely slow the truck down through the power train. No more butt-puckering down steep hills in your pick-up or medium duty truck!
