STEMCO, a manufacturer of heavy-duty components and solutions for commercial vehicles, has released the Lunar line of air disc brakes.

The Lunar products complement STEMCO’s established lines of brake products including brake drums, friction components and automatic brake adjusters. The air disc brake product line includes two conventional air disc brake pads. Lunar is a high-quality aftermarket air disc pad made to fit, form and function as well as or better than OE. Lunar HP is built for extreme heavy-duty applications that demand extra performance while delivering improved stopping power.  

As part of STEMCO’s focus on making the roadways safer, the company says each part number has been tested to ensure it performs within a narrow tolerance of OEM parts in accordance with ECE Regulation 90.

Compared to other braking technologies, air disc brakes more easily achieve shorter maximum stopping distances mandated in Federal Motor Vehicle Safety Standard 121 (FMVSS 121) from the National Highway Safety Administration. Choosing air disc brakes also may allow fleet managers to shave 30 to 40 percent off the weight of brake systems while still meeting new stopping requirements, according to STEMCO.

Traditional air disc components, however, can run hot, causing premature wear. Lunar and Lunar HP brake pads are specifically formulated to meet rigorous demands without degrading due to prolonged exposure to friction and heat, which increases longevity and stopping performance, the company says.

“The Lunar line benefits from our long experience with engineered friction components,” said Jim Reis, vice president and general manager for STEMCO Brake Products. “These brake pads can dissipate heat rapidly, even under severe operating conditions. They last longer, preserve other brake components, including the rotor, which means vehicles in your fleet are on the road more and in the shop less, all while improving safety.”
