About the C-TEK Standard Disc Brake Rotors Line

The C-TEK Standard Disc Brake Rotors line by Centric focuses on providing dependable, OE-quality replacement rotors designed to meet or exceed original equipment specifications. This product line emphasizes precise fitment and consistent braking performance, making it suitable for vehicles requiring solid rotors with smooth surfaces. The 121.39000 rotor is part of this line, offering a balance of durability and performance for standard braking applications.

Detailed Product Description

The Centric 121.39000 disc brake rotor features a solid design with a smooth surface, optimized for vehicles that require a floating disc mounting system. Its 10.728-inch outside diameter and 0.500-inch nominal thickness ensure compatibility with specific vehicle models that demand these dimensions. The rotor’s discard thickness of 0.449 inches indicates the minimum thickness before replacement is necessary, helping maintain safe braking performance. With five lug holes sized at 0.650 inches and a mounting bolt hole circle diameter of 108 mm, this rotor fits vehicles with these specifications. The absence of an ABS tone ring means it is intended for vehicles without ABS sensor integration on the rotor itself.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation or noise
• Restores proper braking performance on vehicles with disc brake systems requiring solid rotors
• Addresses rotor thickness below manufacturer discard limits to maintain safety
• Eliminates uneven brake pad wear due to rotor surface imperfections
• Suitable for vehicles needing a floating disc mounting type rotor

Installation Notes and Tips

• Verify vehicle compatibility by matching rotor dimensions and bolt pattern
• Ensure rotor thickness is within nominal specifications before installation
• Clean rotor surface to remove any protective coatings prior to mounting
• Torque lug nuts to manufacturer specifications to avoid rotor warping
• Check for ABS sensor compatibility since this rotor does not include a tone ring
