Product Line Details: C-TEK Standard Disc Brake Rotors
The C-TEK Standard Disc Brake Rotors line by Centric offers a balance of quality and value, focusing on standard replacement rotors that meet OEM specifications. This product line emphasizes consistent thickness and smooth surface finishes to ensure proper pad contact and braking efficiency. The vented rotor design in this line, including part number 121.51000, helps maintain optimal operating temperatures by promoting airflow, which reduces the risk of brake fade during normal driving conditions.
Technical Specifications and Features
This Centric rotor features a nominal thickness of 0.866 inches (22.000 mm) and a discard thickness of 0.787 inches (20.000 mm), indicating the minimum thickness before replacement is necessary. The overall height is 1.780 inches (45.200 mm), and the outside diameter is 10.118 inches (257.000 mm), matching Hyundai Sonata factory dimensions. The rotor uses a floating disc mounting style with a straight vane design to enhance heat dissipation. It includes four stud/lug holes with a diameter of 0.500 inches (12.700 mm) and a mounting bolt hole circle diameter of 4.500 inches (114.300 mm). This rotor does not include an ABS tone ring or bearings, so those components must be sourced separately if required.
Common Applications and Problem Solving
- Replacement for worn or warped rotors on Hyundai Sonata models
- Addresses brake pulsation caused by uneven rotor surfaces
- Helps restore braking performance diminished by rotor thickness below discard limits
- Reduces brake fade through vented rotor design for better heat management
- Suitable for routine maintenance and brake system overhauls
Installation Notes and Tips
- Verify rotor thickness before installation to ensure it meets minimum discard thickness
- Clean rotor surface to remove any protective coatings or debris prior to mounting
- Use proper torque specifications on mounting bolts to avoid rotor warping
- Inspect related brake components such as pads and calipers during installation
- Ensure compatibility with Hyundai Sonata model year and trim for correct fitment
