U.S. Truck and Trailer Air Disc Brake Market to Reach USD 1.80 Billion by 2031 | Market Size, Trends & Forecast 2026-2031 | Arizton

The U.S. truck and trailer air disc brake market is projected to grow from USD 1.49 billion in 2025 to USD 1.80 billion by 2031, at a CAGR of 3.25%. Arizton's analysis shows that the market is entering a phase where new truck production and the growing installed base are creating two different sources of demand. OEMs benefit when braking systems are specified and installed at the factory, while aftermarket demand builds later as those vehicles age and require replacement components.

This distinction is becoming more important as disc brakes gain wider adoption across commercial vehicles. OEM remains the largest sales channel, supported by fleet procurement, factory standardization, new vehicle architectures, warranties, and dealer networks. At the same time, aftermarket is growing faster as more air-disc-brake-equipped trucks move beyond warranty and create recurring demand for pads, rotors, and related components. The result is a market where today's OEM installations are also building the installed base that will drive future aftermarket demand.

OEM Demand Is Tied to New Truck Production
OEMs account for the largest share of the U.S. truck and trailer air disc brake market because braking systems are increasingly being built into the truck from the start. Large trucking companies can order thousands of vehicles at once, giving truck manufacturers and brake suppliers the scale to secure high-volume factory installations. As disc brakes become standard equipment, particularly on front axles, this demand becomes part of the vehicle rather than an option the fleet has to purchase separately.

The same approach is carrying into the next generation of heavy trucks. Electric, hydrogen, and automated vehicles require braking systems that work with electronic controls and new chassis designs, so brake suppliers are involved earlier in vehicle development. Once the system is integrated into a vehicle platform, the relationship can continue through extended warranties, dealer servicing, regional parts availability, and maintenance-inclusive leasing.

This combination of factory installation and continued service support gives the OEM channel a broader role across the truck's lifecycle.

Aftermarket Demand Is Increasing with the Installed Base
The aftermarket is registering faster growth as more air-disc-brake-equipped trucks move beyond their original warranty periods. This is creating more room for independent suppliers as fleets gain flexibility in choosing replacement components.

Trucks equipped with disc brakes and manufactured in the late 2010s and early 2020s are now moving beyond their original factory warranty periods. As these vehicles remain in operation and enter the used truck market, they generate recurring demand for brake pads, rotors, and related components.
Independent suppliers are expanding private-label disc brake offerings to serve fleets looking for lower-cost alternatives to official dealer components. Broader catalogs covering multiple truck and trailer brands also make it easier for fleets with mixed vehicle populations to source compatible parts from a single supplier.

Parts availability is another area where independent suppliers can compete. Online platforms can connect fleet maintenance requirements with parts catalogs and local inventory, allowing fleets to identify compatible components, check availability, and arrange delivery without relying entirely on traditional dealer networks.

As more vehicles move beyond warranty coverage, price, compatibility, and parts availability are becoming increasingly important factors in replacement purchasing, supporting the faster growth of the aftermarket channel.

Technology Is Changing How Air Disc Brakes Are Used
Air disc brakes are also becoming more connected to the way trucks are built and maintained. Electric, hydrogen, and automated trucks are bringing more electronic controls into braking systems, while fleets are looking for better ways to track brake wear and reduce unexpected maintenance.

This is pushing brake suppliers to work more closely with truck manufacturers during vehicle development. In February 2026, Knorr-Bremse announced plans to invest up to €200 million over five years in a modular campus in Chennai, India, planned as a technology and AI hub.

The same shift is visible in fleet maintenance. SAF-HOLLAND introduced BrakeSight in March 2026 to provide continuous visibility into air disc brake pad and rotor wear. This gives fleets more information on when brake components need attention.

Product design is changing as well. Cummins plans to introduce the QuikDisc Rotor for U-series wheel ends in North America in late 2027. The two-piece hub and rotor design is intended to make rear-axle rotor servicing easier.

These developments show that air disc brakes are no longer being treated only as braking components. Their role is increasingly connected to vehicle electronics, maintenance monitoring, and how trucks are serviced over their operating life.

U.S. Air Disc Brake Market: OEM, Aftermarket & Forecast Analysis
The U.S. truck and trailer air disc brake market is developing along two connected demand cycles. OEM demand is tied to how braking systems are specified and integrated into new trucks, while aftermarket demand develops as those vehicles remain in service, move beyond warranty, and require replacement components.

The analysis also shows how this channel shift is being influenced by changes in truck architecture, fleet procurement, maintenance practices, parts availability, and the growing use of electronic braking and monitoring systems. These factors are creating different demand patterns across the OEM and aftermarket sides of the market.
