Its drum-in-hat design integrates a drum brake surface for rear parking brake functionality, making it suitable for vehicles equipped with this system. The rotor measures 10.95 inches in outside diameter and 2.01 inches in overall height, with a nominal thickness of 0.43 inches (11 mm) and a discard thickness of 0.35 inches (9 mm), providing clear service limits for maintenance. The 5 mounting bolt holes are spaced on a 4.65 inch (118 mm) bolt circle diameter, with each hole measuring 0.63 inches (16.1 mm) in diameter. A rust-resistant coating helps protect the rotor surface from corrosion, which is especially beneficial in humid or road salt environments. This rotor does not include an ABS tone ring and features a non-directional braking surface, allowing for flexible installation orientation.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBuick Regal and Century models requiring rear drum-in-hat rotors\u003c\/li\u003e\n\u003cli\u003eChevrolet Impala and Monte Carlo with compatible rear disc brake systems\u003c\/li\u003e\n\u003cli\u003eOldsmobile Alero and Intrigue models with matching rotor specifications\u003c\/li\u003e\n\u003cli\u003ePontiac Grand Am and Grand Prix vehicles equipped with rear drum-in-hat rotors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eVerify rotor dimensions and bolt pattern against your vehicle’s specifications before installation\u003c\/li\u003e\n\u003cli\u003eEnsure the rotor surface is clean and free of contaminants prior to mounting\u003c\/li\u003e\n\u003cli\u003eCheck the nominal and discard thickness to determine if rotor replacement is necessary\u003c\/li\u003e\n\u003cli\u003eUse proper torque specifications for mounting bolts to avoid warping\u003c\/li\u003e\n\u003cli\u003eInspect brake pads and hardware during rotor replacement for optimal braking 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 standards for fit, form, and function.
