Product Line Details: Centric Premium High Carbon Alloy Disc Brake Rotors

The Centric Premium High Carbon Alloy Disc Brake Rotors line focuses on enhanced rotor durability and thermal management through the use of high carbon alloy materials. This product line is designed to reduce brake fade and improve rotor life, making it suitable for performance-oriented vehicles like the Audi S7 Sportback and Maserati Q8 e-tron. The 125.33155 rotor benefits from this advanced metallurgy and vented design to maintain consistent braking under demanding conditions.

Technical Specifications and Features

This disc brake rotor features a nominal thickness of 28 mm and a discard thickness of 26 mm, ensuring a clear service limit for safe operation. The rotor’s overall height measures 36.3 mm, with an outside diameter of 350 mm, matching factory specifications for compatible vehicles. The rotor includes five bolt holes arranged on a 112 mm bolt circle diameter, with stud/lug holes sized at 15.3 mm diameter. The floating disc mounting design allows for slight movement to reduce stress and improve braking smoothness. The coated hat finish provides corrosion resistance, extending rotor life, while the smooth surface type supports consistent pad contact and wear.

Common Issues Addressed by This Rotor

• Brake rotor warping due to excessive heat
• Uneven rotor wear causing vibration during braking
• Corrosion and rust buildup on rotor surfaces
• Reduced braking efficiency from worn or thin rotors
• Brake noise and pulsation from damaged rotors

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets the nominal thickness of 28 mm and is above the discard thickness of 26 mm. Clean the rotor surface to remove any protective coatings or contaminants before mounting. Verify bolt hole alignment with the 112 mm bolt circle diameter and use proper torque specifications for the five lug bolts. This rotor does not include ABS tone rings or bearings, so confirm compatibility with your vehicle’s braking system. Proper bedding-in of brake pads after installation is recommended to optimize braking performance.
