Centric 125.33133 Disc Brake Rotor - Rear

Centric Rear Brake Rotor for Audi Performance Fitment

The Centric Premium High Carbon Alloy Disc Brake Rotor, part number 125.33133, is built for rear brake applications that demand stable stopping performance and reduced noise. It is engineered for select Audi models, including Audi A7 Sportback, Audi S4, Audi A8 Quattro, Audi S6, and Audi S7 rear brake service.

Key Features

• High carbon alloy metallurgy helps reduce pad squeal with higher-friction European brake pad compounds
• Molybdenum and chromium alloy content improves resistance to cracking during repeated stops and higher-load use
• Increased carbon and chromium content improves oxidation resistance
• Vented rotor design supports heat management in rear brake applications
• 356 mm outside diameter with 21.8 mm nominal thickness and 20 mm discard thickness
• Coated hat finish and smooth surface type
• Floating mounting type with pillar vane style
• 5-bolt pattern, 68 mm center hole diameter, and 112 mm bolt circle diameter

Product Details

Centric’s Premium High Carbon Alloy Disc Brake Rotors line focuses on metallurgy that works well with European braking systems. For rear brake service on Audi platforms, this rotor uses a high-carbon alloy blend to improve friction characteristics and help maintain consistent pedal feel under repeated braking. The coated hat finish adds corrosion resistance where the rotor meets the hub, while the vented, pillar-vane construction supports thermal stability during everyday driving and performance-oriented use. Part number 125.33133 is a direct-fit rear rotor for multiple Audi applications, including 2013-2018 Audi A8 Quattro, 2013-2018 Audi S6, and 2018-2023 Audi S4 rear brake setups.

This part cross-references Raybestos Brakes 980878 for the same application.

Common Issues This Rotor Addresses

• Brake squeal from high-friction pad compounds
• Rotor cracking during repeated stop-and-go braking
• Reduced braking consistency from heat buildup
• Surface oxidation on exposed rotor areas
• Wear-related replacement of a rear 356 mm Audi brake rotor

Installation Notes and Tips

Verify rotor diameter, center hole diameter, bolt pattern, and rear-position fitment before installation. This rotor is listed for rear applications only and uses a floating mounting design with a vented, smooth-surface construction. For best results, inspect pads, caliper condition, and hub surfaces during service, and follow the vehicle manufacturer’s brake bedding procedure after installation. Compatible With Audi rear brake service applications such as the A7 Sportback, S4, A8 Quattro, S6, and S7.

Quality Assurance

Centric manufactures this rotor with high-carbon alloy metallurgy and corrosion-resistant surface treatment to support consistent brake performance in demanding use. Part number 125.33133 is built to meet the dimensional and fitment requirements listed for the specified Audi rear brake applications.
