12-3140-122 BENSCO BRAKE DISC – KIA MOTORS MAXI ‘D’/KIA BESTA FRONT SET

The Bensco 12-3140-122 is a commercial-grade front brake disc rotor manufactured to replace worn factory components on classic Kia Motors commercial platforms, specifically the Kia Besta van and the Kia Maxi ‘D’ pick-up/truck series.
Because these legacy vehicles are dedicated workhorses designed for local logistics, cargo delivery, or passenger transport, their front braking systems are subjected to constant high-stress situations. Understanding the deep mechanical and historical details of this rotor ensures your utility vehicle remains safe and operational.
Detailed Technical Specifications
Outer Diameter (OD): Features a compact, thick outer diameter optimized to clear the inner barrel of classic 14-inch commercial steel wheels. This ensures maximum torque delivery while keeping the brake assembly safe from external road debris.
Solid (Non-Vented) Configuration: Unlike modern passenger cars that use hollow, vented rotors, this specific commercial part profile relies on a solid, high-density single-plate design. It uses thicker, solid cast grey iron to absorb massive kinetic energy through pure material density, rather than relying on air vanes.
Wear Limits: Because commercial use accelerates rotor wear, it is critical to observe the stamped minimum service discard thickness on the rotor edge. Running a solid rotor below its minimum thickness reduces its ability to absorb heat, risking structural cracking or pedal fade when the vehicle is hauling a full cargo payload.
Wheel Hub Architecture: Designed with a multi-hole commercial bolt pattern engineered to slip directly onto the heavy-duty front wheel hubs. It features countersunk mounting holes to properly lock the rotor assembly onto the front axle flange.
