Disk brakes on semi trucks have revolutionized the way we think about reliable braking.

They offer superior heat dissipation, which is crucial for high-speed applications like semi trucks.

With their ability to dissipate heat quickly, disk brakes can handle the intense heat generated by frequent braking, reducing the risk of brake fade.

In fact, studies have shown that disk brakes can reduce stopping distances by up to 30% compared to traditional drum brakes.

Here are some specific models that are compatible with air disc brakes:

Some models, like the Hendrickson MAXX22T, are not available with air disc brakes on certain models, such as the AAEDT 30K and AAEDL 30K. Be sure to check the specifications before making a purchase.

Air disc brakes are also available with advanced features like TIREMAAX PRO, which allows air to flow in both directions – to and from tires. This can help improve braking performance and safety.

If you're looking for a specific type of air disc brake, be sure to check the availability on your vehicle's suspension or axle model. For example, the WABCO PAN17 is only available on the HT250U suspension with TRLAXLE, 6.5-inch ride height, and limited tracks.

  • The only ADB system offered with Hendrickson comprehensive warranty coverage
  • Outboard Mounted Rotor available with HXL7 wheel-end systems

Semi?

A semi-automatic brake system is a type of brake system that uses a combination of mechanical and hydraulic components to slow or stop a vehicle.

In a semi-automatic system, the driver still needs to press the brake pedal, but the system then takes over and engages the brakes automatically, providing more control and precision.

This type of system is commonly found in high-performance vehicles, where precise control over braking is crucial for safety and performance.

The semi-automatic system can also help to reduce wear and tear on the brake pads and rotors, as it can apply the brakes more smoothly and evenly.

In addition, semi-automatic systems often include features like automatic brake calibration, which can help to ensure that the brakes are functioning properly and consistently.

Brake Components

Disk brakes on semi trucks rely on several key brake components to function properly.

The brake caliper is a critical component, as it houses the brake pads that come into contact with the rotor to slow the vehicle.

A typical semi truck brake caliper is designed to withstand high temperatures and friction, with some models featuring a heat-dissipating design to prevent warping.

The brake pads themselves are made of a durable material that can withstand the intense heat generated by repeated braking.

In addition to the caliper and brake pads, the brake rotor is another essential component that needs to be maintained regularly to ensure smooth braking performance.

The rotor is typically made of a durable metal alloy that can withstand the high temperatures generated by braking, and is designed to be replaced when it becomes worn.

Hendrickson Suspensions and Axles with Air Brakes

Hendrickson offers a range of suspensions and axles available with air disc brakes (ADB). These include INTRAAX, INTRAAX SP, VANTRAAX, ULTRAA-K, and TRLAXLE models.

The availability of ADB on Hendrickson suspensions and axles varies by model and wheel size. Here's a breakdown of the options:

Some models, such as INTRAAX and TRLAXLE, are available with ADB in multiple wheel sizes.

Knorr-Bremse Rationalized Calipers

Knorr-Bremse Rationalized Calipers are a cost-efficient solution for brake maintenance. By replacing only the caliper, you can save time and reduce storage space needed.

This approach also reduces variants, making it easier to manage inventory. The caliper is a critical component that can be replaced separately, without having to replace the entire disc brake.

Replacing the caliper is a more straightforward process, making service more efficient. This can be especially beneficial for commercial vehicle owners who need to get back on the road quickly.

With Knorr-Bremse's rationalized calipers, you can get back on the road fast with a reliable brake system.

Reliability is key when it comes to brake calipers in commercial vehicles, with forces of over 25 tonnes developed during braking.

Air Disc Brakes from Knorr-Bremse can withstand these enormous forces without losing function, proving their strength and durability through millions of miles on the road.

Brake systems in commercial vehicles are exposed to temperatures of over 900 degrees, vigorous movements, vibrations, cold, moisture, dust, and dirt.

WABCO's PAN™ and MAXX™ single-piston air disc brakes improve vehicle safety and reduce total cost of ownership compared to traditional drum braking technologies.

Proper maintenance is crucial to avoid expensive repairs and unsafe driving conditions, which can be caused by deteriorating brake pads that also lead to excessive wear on other vehicle elements.

Brake Chambers ensure the correct transmission of pressure to the brake, efficiently converting air pressure into a mechanical output force to brake the vehicles.

Frequently Asked Questions

Can you convert drum brakes to disc on a semi-truck?

No, drum brakes to disc conversions are not suitable for semi-trucks, including dually axles. If you're looking to upgrade your semi-truck's braking system, consider contacting Lugnut4x4 for alternative solutions.

Why are disc brakes not used in trucks?

Disc brakes are not commonly used in trucks due to high rotor wear rates in dusty or gritty environments, which can be costly to replace. This has led some fleets to switch back to drum brakes despite their higher maintenance needs.
