The cross-drilled surface helps reduce brake fade by allowing gases and heat to escape more efficiently during heavy braking. The solid rotor construction provides a stable braking surface, while the coated hat finish protects against rust and corrosion, making it suitable for daily driving and spirited use on compatible Mercedes-Benz vehicles.\u003c\/p\u003e\u003ch2\u003eDetailed Product Description\u003c\/h2\u003e\u003cp\u003eThis StopTech rotor (128.35090R) is a solid disc brake rotor featuring a cross-drilled surface type that aids in heat dissipation and brake pad cleaning. The rotor’s nominal thickness is 0.551 inches (14.000 mm), with a discard thickness of 0.449 inches (11.400 mm), ensuring a clear service life indicator. The overall height measures 2.476 inches (62.900 mm), and the outside diameter is 12.992 inches (330.000 mm), matching the specifications required for Mercedes-Benz GL and ML series models as well as R-Class variants. The rotor includes five lug holes with a 4.409-inch (112.000 mm) bolt circle diameter and a center hole diameter of 2.638 inches (67.000 mm), ensuring proper alignment and fitment. This rotor does not include an ABS tone ring or bearings, so it is intended for vehicles where these components are separate or already installed.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCompatible with Mercedes-Benz GL320, GL450, ML320, ML350, ML450, ML500, ML550, R320, R350, and R500 models\u003c\/li\u003e\n\u003cli\u003eAddresses brake fade caused by excessive heat during aggressive driving or towing\u003c\/li\u003e\n\u003cli\u003eHelps reduce rotor warping and uneven pad wear through improved heat dissipation\u003c\/li\u003e\n\u003cli\u003ePrevents corrosion on the rotor hat area with a protective coating\u003c\/li\u003e\n\u003cli\u003eSuitable replacement for worn or damaged factory rotors to restore braking performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnsure rotor thickness is above discard thickness before installation\u003c\/li\u003e\n\u003cli\u003eClean rotor surface with brake cleaner to remove any protective oils before mounting\u003c\/li\u003e\n\u003cli\u003eVerify bolt pattern and center hole diameter match vehicle hub specifications\u003c\/li\u003e\n\u003cli\u003eTorque lug nuts to manufacturer specifications to avoid rotor distortion\u003c\/li\u003e\n\u003cli\u003eCheck compatibility with existing brake pads and calipers on Mercedes-Benz GL and ML series or R-Class vehicles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eStopTech Sport Cross-Drilled Disc Brake Rotors are manufactured to meet or exceed OEM standards for fit, form, and function.
