The Geomet disc finish and coated hat finish add corrosion protection where road moisture and brake dust can be a concern.

This Bosch QuietCast Disc Brake Rotor part number 53011433 is sized for the listed front applications and uses a directional braking surface, 325 mm outside diameter, and 30 mm nominal thickness. This part cross-references Hyundai/Kia OE numbers 51712GI000 and 51712L0100 for the same application.

What It Helps Address

• Brake pulsation caused by worn or uneven rotor surfaces
• Reduced braking consistency from heat-affected front rotors
• Corrosion on exposed rotor surfaces and hat areas
• Noise or vibration related to rotor wear
• Front brake service needs on Hyundai Ioniq 5, Hyundai Tucson, Hyundai Ioniq 6, Kia EV6, and Kia Sportage

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, center bore, and front-position fitment before installation. Clean the hub mounting surface thoroughly to help prevent rotor runout, and inspect pads, calipers, and hardware condition during brake service. Because this rotor is supplied without a hub assembly and without bearings, reuse or replacement of related components should be confirmed separately based on the vehicle’s brake setup.

Quality Assurance

Bosch QuietCast brake components are built around OE-style fit, finish, and corrosion protection for direct replacement service. The Bosch 53011433 rotor is manufactured with a coated finish and rust-resistant coating to support dependable front brake performance in the listed Hyundai and Kia applications.
