Cummins Inc. recently announced the Meritor MFLEX4™ air disc brake pad, a patent-pending solution engineered for durability, versatility and broad fitment coverage.

The MFLEX4 is designed for broad fitment coverage across commonly used heavy-duty air disc brake systems, and is compatible with school bus models using the supported caliper models: Bendix® ADB22X®, Hendrickson MAXX22T™, WABCO MAXXUS™, or WABCO PAN22™. 

Key Features

• Simplified inventory: Fewer SKUs to help streamline ordering and stocking.

• Efficiency-focused design: Meritor® Positive Pad Retraction (PPR) springs are designed to help improve fuel efficiency and extend rotor and pad life under typical operating conditions.

• Performance options: Two friction mixes – linehaul and severe service – are engineered to meet or exceed applicable original equipment (OE) pad performance standards.

• Predictable pricing: Uniform pricing across all four caliper applications intended to support cost predictability.

• Warranty coverage: Includes a limited one-year warranty, along with continued Bendix® ADB22X® caliper warranty coverage.

• All-in-one installation kits: Each kit is designed to include everything technicians need for installation.

“The MFLEX4 is a technician-friendly solution that directly addresses common challenges, such as fitment complexity, parts proliferation, and service efficiency,” said Jason Soika, North American aftermarket general manager for Cummins Drivetrain and Braking Systems. “By combining Meritor’s OE expertise with aftermarket insights, we’re empowering parts dealers and distributors to streamline their operations and helping fleets maximize uptime with a high-quality, cost-effective product.”

The MFLEX4 pad is available through Meritor aftermarket distributors across North America.
