Centric 125.34086 Disc Brake Rotor - Rear

Centric Rear Brake Rotor for BMW 750i, 750Li, 760i, 760Li

Centric Premium High Carbon Alloy Disc Brake Rotor part number 125.34086 is built for rear brake service on select BMW 7 Series applications. It combines a vented, smooth rotor design with high-carbon alloy metallurgy to support consistent braking performance, reduced noise, and improved resistance to heat-related stress.

Key Features

• High carbon alloy construction for improved resistance to cracking during repeated stops and higher-load braking
• Advanced metallurgy helps reduce pad squeal, especially with higher-friction European brake pad compounds
• Vented rotor design supports heat management during demanding driving conditions
• Straight vane style for airflow through the rotor
• Coated hat finish helps resist oxidation on exposed surfaces
• 5-bolt mounting pattern with 120 mm bolt circle and 78.9 mm center hole diameter
• Outside diameter: 344.6 mm; nominal thickness: 23.8 mm; discard thickness: 22.4 mm

Product Details

The Centric Premium High Carbon Alloy Disc Brake Rotors line is engineered for drivers who want a rotor material that better handles heat, friction, and corrosion exposure than standard iron formulations. For BMW 750i, BMW 750Li, BMW 760i, and BMW 760Li rear brake applications, part number 125.34086 uses a smooth friction surface and vented construction to support stable pedal feel and repeat-stop performance. The alloy content also helps improve the friction couple, which can contribute to more effective braking response when paired with the correct pad compound.

This part cross-references Raybestos Brakes 980649 and FEL-PRO 73031 for the same application.

What It Helps Address

• Brake squeal during everyday or performance-oriented stopping
• Rotor cracking from repeated high-heat braking events
• Reduced braking consistency under stop-and-go or spirited driving
• Surface oxidation on exposed rotor areas
• Wear-related replacement needs on rear BMW 7 Series brake systems

Verify rotor dimensions, hub bore, bolt pattern, and rear axle application before installation. Clean the hub mounting surface thoroughly and inspect pads, caliper hardware, and wheel bearings for wear before returning the vehicle to service. Part number 125.34086 is a rear disc brake rotor for compatible BMW 7 Series fitments only.

Quality Assurance

Centric’s Premium High Carbon Alloy rotor line uses proprietary molybdenum and chromium alloy content to improve crack resistance and oxidation resistance while supporting dependable braking performance in demanding use.
