Centric 125.34117 Disc Brake Rotor - Rear

Centric Rear Brake Rotor for BMW and Mercedes-Benz

The Centric Premium High Carbon Alloy Disc Brake Rotor, part number 125.34117, is built for rear brake applications that demand stable stopping performance and consistent pedal feel. It is engineered for select BMW 550i GT, 750i, 750Li, 760Li, and Mercedes-Benz SLK55 AMG models.

Centric’s 125 Series High Carbon Alloy rotor line uses an advanced metallurgy approach to help reduce pad squeal, improve resistance to cracking under repeated stops, and slow oxidation on the rotor surface. The result is a rear disc brake rotor designed for drivers who want dependable braking performance with European-style pad compounds.

Product Details

Centric Premium High Carbon Alloy Disc Brake Rotors are built around a metallurgy package that includes proprietary molybdenum and chromium content. That material choice helps the rotor handle repeated stop-and-go use, supports crack resistance during higher-load braking, and improves oxidation resistance over time. For drivers searching for a rear brake rotor for BMW 750i rear, BMW 750Li xDrive rear, or Mercedes-Benz SLK55 AMG rear applications, this rotor matches the fitment and performance requirements listed below.

This part cross-references Raybestos Brakes 980804 for the same application. Part number 125.34117 also cross-references 34433, 45532, 45532G, 880804, 980804P, and 34216775291.

What It Helps Address

• Brake squeal with higher-friction European brake pads
• Rotor cracking during repeated hard stops
• Reduced braking consistency from worn rear rotors
• Surface oxidation on exposed rotor areas
• Loss of stopping performance caused by rotor wear beyond discard thickness

Installation Notes

Verify rotor dimensions, hub fitment, and rear axle application before installation. This rotor uses a floating/DIH mounting type, a 5-lug pattern, and a vented straight-vane design. Inspect pads, calipers, and hub surfaces during service so the new rotor seats evenly and performs as intended.
