Kia CEE's Front Brake Disc Model D

Applicable OE Brands: Imported Hyundai / Imported Kia
This product is a front brake disc made of high-strength cast iron. Internal ventilation dissipates braking heat to prevent brake fade. Electroplated anti-rust surface protects non-friction surfaces from oxidation during installation and initial running-in.
Differentiated Scenario Description Based on Target Vehicle Model Usage Characteristics
517121M000 is a main front brake disc part number shared by Hyundai and Kia K-platform vehicles, applicable to Sorento, Sportage, Tucson and Santa Fe. Analysis of three core usage scenarios:

Scenario 1: Pickup Trucks & Off-road SUVs - Kia Sorento, Hyundai Santa Fe
Main daily scenarios for midsize and large SUV owners are family trips, long-distance cross-country driving and light towing, which require stable, reliable braking margin under heavy weight.
Sorento's curb weight approaches or exceeds 1.8 tons; fully loaded seven-passenger Santa Fe weighs more. For users frequently towing ~2000kg caravans or carrying camping gear, 517121M000 has a unique internal ventilation structure. On long downhill roads, evenly distributed ventilation ribs boost air convection, keep surface temperature within HT250 cast iron's optimal thermal fade threshold, and prevent overheating-caused surface stress deformation.
After driving on muddy or unpaved roads, the coated disc surface removes water films quickly after gentle braking, restores dry-condition friction coefficient, and guarantees heavy-load braking safety.

Scenario 2: Japanese and Korean Family Sedans - Kia K3, Hyundai Elantra
Core criteria for K3 and Elantra braking system are smooth commuting, fuel economy and quiet riding. 517121M000 surface adopts high-precision finishing, conforms to original factory roughness standard Ra 1.0μm~Ra 2.0μm. Precise tolerance matching ensures even contact between brake pads, eliminates common low-frequency squealing and dull rumbling during medium-low speed braking.
Each brake disc receives strict single-piece dynamic balance correction before delivery, eliminates minor deflection torque from uneven casting density. In congested urban traffic with frequent braking, the coating ensures smooth linear brake pedal feel, avoids steering wheel vibration, and creates a quiet comfortable riding atmosphere.

Scenario 3: High-performance Sports Cars - Kia K5, Hyundai Sonata
Drivers of 2.0T turbocharged sport-tuned vehicles have higher requirements for corner entry braking and successive aggressive acceleration. 517121M000 uses HT250 gray cast iron as base material with optimized thermal durability for these conditions.
When braking hard before entering curves at high speed, brake disc surface temperature can reach 400-600°C in seconds. With standard thickness 26mm and minimum thickness margin 24.4mm, this product has large heat capacity, stores heat well in repeated hard braking, and significantly delays thermal fade.
Precise balance calibration keeps lateral runout extremely low at high rotating speeds. When decelerating from 100km/h to 40km/h abruptly, it will not cause brake pedal pulsation or steering wheel shaking, improving driving confidence in high-performance driving.
