About Centric Premium High Carbon Alloy Disc Brake Rotors

The Centric Premium High Carbon Alloy Disc Brake Rotors line is designed to provide enhanced durability and performance through the use of high carbon alloy materials. This construction helps reduce rotor warping and cracking under high thermal stress. The rotors feature a coated hat finish to protect against rust and corrosion, extending service life. The vented design improves heat dissipation, which is critical for maintaining braking efficiency during extended use. The 125.35017 rotor is a part of this line, offering a balance of OEM fitment and material quality for Mercedes-Benz vehicles.

Detailed Product Description

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to reduce heat buildup during braking. It has a smooth surface type that ensures even brake pad wear and consistent braking performance. The rotor measures 300 mm in outside diameter with a nominal thickness of 27.9 mm and a discard thickness of 25.4 mm, indicating when replacement is necessary. The hat is coated to resist corrosion, and the rotor mounts behind the hub using five bolt holes arranged in a 112 mm bolt circle diameter. The center hole diameter is 80 mm, matching the hub size for proper fitment. This rotor does not include ABS tone rings or bearings.

Applications and Problem Solving

• Replacement for worn or warped rotors on Mercedes-Benz 300SD, 300SDL, 300SE, 300SEL, 350SD, 350SDL, 420SEL, 560SEC, and 560SEL models
• Addresses brake pulsation caused by rotor thickness variation
• Improves braking consistency by restoring proper rotor thickness and surface condition
• Helps reduce brake fade through vented rotor design
• Prevents corrosion-related rotor damage with coated hat finish

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (25.4 mm) before installation
• Clean mounting surfaces and hub to ensure proper rotor seating
• Torque mounting bolts to manufacturer specifications for secure fitment
• Check compatibility with vehicle ABS system as this rotor does not include an ABS tone ring
• Inspect brake pads and replace if worn to maintain optimal braking performance
