Its vented design enhances airflow between the rotor faces, reducing heat buildup during braking and helping to maintain consistent performance under demanding conditions. The drum-in-hat style integrates a parking brake drum within the rotor, making it compatible with vehicles equipped with drum-in-hat parking brake systems. This rotor does not include an ABS tone ring and features a non-directional braking surface, allowing for flexible installation without concern for rotor orientation.\u003c\/p\u003e\u003cp\u003eWith an outside diameter of 12.99 inches (330 mm) and a mounting bolt pattern of 5 holes spaced on a 4.41 inch (112 mm) bolt circle, the BR900878 is specifically designed to fit a range of Mercedes-Benz SUVs and crossovers, including the GL320, GL350, GL450, GL550, ML320, ML350, ML500, ML550, R320, R350, and R500 models.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Issues Addressed\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors causing brake pulsation\u003c\/li\u003e\n\u003cli\u003eRestores braking efficiency on Mercedes-Benz GL and ML series vehicles\u003c\/li\u003e\n\u003cli\u003eAddresses rotor thickness below manufacturer discard limits\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade during heavy use\u003c\/li\u003e\n\u003cli\u003eCompatible with drum-in-hat parking brake systems to maintain parking brake function\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnsure rotor thickness meets or exceeds nominal thickness of 0.87 inches (22 mm) before installation\u003c\/li\u003e\n\u003cli\u003eCheck mounting bolt hole alignment with 5-hole, 112 mm bolt circle pattern\u003c\/li\u003e\n\u003cli\u003eClean hub surface to prevent rotor runout and ensure proper fit\u003c\/li\u003e\n\u003cli\u003eTorque mounting bolts to manufacturer specifications for secure installation\u003c\/li\u003e\n\u003cli\u003eInspect brake pads and calipers during rotor replacement for optimal braking system performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDuraGo disc brake rotors are manufactured to meet or exceed OEM specifications for fit, form, and function.
