Frequently Asked Questions
What is the Brembo 09.B746.51?
The Brembo 09.B746.51 is an OE-grade replacement front brake rotor for the 2012 Mercedes-Benz E350 and 2010-2011 Mercedes-Benz E550. The BRE09.B746.51 is manufactured by Brembo to match the factory rotor dimensions, mounting pattern, and vane count of the original front rotor on these W212 E-Class models, providing a direct bolt-on fit without modification.
Does the Brembo 09.B746.51 fit both the E350 and E550?
Yes, with year-specific fitment. The 09.B746.51 fits the 2012 Mercedes-Benz E350 and the 2010-2011 Mercedes-Benz E550. It does not cover all years of both models equally. Confirm your specific year and model before ordering, and verify the front rotor diameter and bolt pattern against your vehicle’s brake specifications to ensure the 09.B746.51 matches your application.
Is the Brembo 09.B746.51 sold as a single or a pair?
The BRE09.B746.51 is sold as a single front rotor. For a complete front axle rotor replacement on the Mercedes-Benz E350 or E550, two rotors are required. Order a quantity of two to replace both front rotors at once. Replacing front rotors in pairs is always recommended to maintain even braking force side to side.
Does the Brembo 09.B746.51 require new brake pads?
It is strongly recommended to replace brake pads whenever replacing rotors on any vehicle, including the Mercedes-Benz E350 and E550. Worn pads on a new rotor surface cause uneven wear and prevent proper pad bed-in. Replacing rotors and pads together ensures optimal braking performance and extends the service life of both components.
Is the Brembo 09.B746.51 a direct OEM replacement?
Yes. The Brembo 09.B746.51 is designed as a direct OE replacement rotor for the 2012 E350 and 2010-2011 E550, matching the factory rotor in all critical dimensions including diameter, hat height, thickness, vane configuration, and bolt circle. No adapters, machining, or modifications are required for installation.
Is resurfacing the existing rotor an option instead of replacing it with the 09.B746.51?
Resurfacing is only possible if the existing rotor is still above the minimum thickness specification after machining. Mercedes-Benz specifies a minimum rotor thickness for the E350 and E550 front rotors in the workshop manual. If the current rotor is worn near or below that specification, resurfacing is not safe and replacement with the Brembo 09.B746.51 is the correct approach.
Does the Brembo 09.B746.51 need to be bedded in after installation?
Yes. New rotors require a bedding procedure to transfer an even friction material layer from the brake pads onto the rotor surface. After installing the 09.B746.51 and new brake pads on the Mercedes-Benz E350 or E550, perform 8 to 10 moderate stops from 30 to 35 mph with adequate cooling time between stops. Avoid hard stops during the first 200 miles while the pads and rotor surface fully mate.
What brake pad compound should I pair with the Brembo 09.B746.51 on the E350 or E550?
For street use on the E350 or E550, a low-dust ceramic or OE-equivalent pad compound paired with the 09.B746.51 provides the best combination of noise, dust, and pad life. Brembo offers OE-spec ceramic pads for the W212 E-Class that are designed to pair with their OE replacement rotors. Avoid race-compound pads on street-driven vehicles as they require higher operating temperatures to function properly.
Installation Instructions
- Safely lift and support the Mercedes-Benz E350 or E550 with the front wheels hanging free.
- Remove the front wheel on the side being serviced.
- Remove the front brake caliper bolts and hang the caliper aside without stressing the brake hose.
- Remove the caliper bracket mounting bolts and remove the bracket.
- Remove the factory front rotor from the hub (a screw or bolt may retain it on the hub if equipped).
- Clean the hub mating surface of any rust or debris using a wire brush and brake cleaner.
- Install the Brembo 09.B746.51 rotor onto the hub and thread the retaining screw finger-tight if applicable.
- Reinstall the caliper bracket and caliper with new brake pads, torquing all hardware to factory specification.
- Reinstall the wheel and lower the vehicle.
- Perform the brake bed-in procedure before driving normally.
