Centric 125.35079 Disc Brake Rotor - Rear

Centric Premium High Carbon Alloy Rotor

The Centric 125 Series High Carbon Alloy Disc Brake Rotor is built for rear brake applications that demand stable stopping performance and consistent pedal feel. Part number 125.35079 uses a vented, smooth-surface design with coated hat finish and high-carbon metallurgy to support quieter operation and better resistance to heat-related wear.

Compatible With 2012-2013 Mercedes-Benz S350 rear and 2003-2004 Mercedes-Benz SL500 rear, this rotor is a direct-fit replacement for select applications. The Centric Premium High Carbon Alloy Disc Brake Rotors line focuses on metallurgy that helps reduce pad squeal, improves resistance to cracking under repeated stops, and offers better oxidation resistance than standard rotor materials.

Detailed Description

Centric 125.35079 is engineered as a rear disc brake rotor for select Mercedes-Benz applications, including the 2012-2013 Mercedes-Benz S350 rear and the 2003-2004 Mercedes-Benz SL500 rear. Its high-carbon alloy composition is used to improve friction characteristics, reduce the chance of brake squeal with higher-friction pad compounds, and increase resistance to cracking during repeated stop-and-go or higher-load braking.

The rotor’s vented, curved-vane design supports heat management during braking, while the coated hat finish helps protect exposed areas from oxidation. With a 300 mm outside diameter, 22 mm nominal thickness, and 19.4 mm discard thickness, this rotor is built to match the dimensional requirements of the listed rear brake applications. This part cross-references Raybestos Brakes 980652 for the same application.

Common Brake Issues It May Address

• Brake squeal from rotor and pad interaction
• Heat-related rotor cracking during repeated stops
• Reduced braking consistency from worn rear rotors
• Surface oxidation on exposed rotor areas
• Vibration or uneven braking caused by rotor wear

Installation Notes and Tips

Verify rotor dimensions, hub bore, bolt pattern, and rear fitment before installation. For best results, inspect pads, caliper hardware, and hub surfaces at the same time, and replace any worn components that could affect rotor contact or braking balance. Clean the rotor friction surface before service to remove protective residue.

Fits 2012-2013 Mercedes-Benz S350, rear. Fits 2003-2004 Mercedes-Benz SL500, rear.
