Product Details

Part number 4312-21012 is a rear disc brake kit from Dynamic Friction that brings together the brand’s GEOSPEC coated rotor line, 3000 ceramic pads, and matching hardware. The rotors use a durable silver-gray coating to help fight corrosion, while the cast iron construction and precision machining are intended to match OE-style durability and stability. The pads are post-cured, scorched, and fitted with rubber-steel-rubber shims to support quieter operation and more consistent pedal feel. This part number 4312-21012 is a practical choice for Kia Forte, Kia Forte Koup, and Kia Forte5 rear brake service when you want a complete rotor-and-pad replacement in one package.

Common Problems This Kit Can Address

• Brake noise from worn pads or fatigued hardware.
• Uneven braking caused by rotor wear or corrosion.
• Excess brake dust from older pad materials.
• Longer stopping distances from reduced pad and rotor performance.
• Vibration or harshness during braking.

Installation Notes and Quality

Install on the rear axle only for the listed Kia applications. The rotors are processed dry and ready to install without additional preparation. For best results, inspect caliper condition, guide hardware, and pad contact points during service. DFC states that the rotors are manufactured to OE specifications and each rotor is fully inspected for critical dimensions and balance. The rotor line includes a 12-month warranty against defects in material and workmanship.
