Its vented design allows air to flow between the rotor faces, helping to dissipate heat during heavy braking and reducing the risk of brake fade. This rotor features a drum-in-hat design, integrating the parking brake drum into the rotor assembly, which is common in many Chevrolet and GMC trucks and SUVs.\u003c\/p\u003e\u003cp\u003eWith an outside diameter of 12.8 inches and a thickness specification that includes a nominal thickness of 0.79 inches and a discard thickness of 0.73 inches, this rotor meets OEM standards for fit and function. The six mounting bolt holes with a 5.5 inch bolt circle diameter ensure secure attachment to the hub. The non-directional brake surface allows for installation on either side of the vehicle without concern for rotor orientation.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cp\u003eThis rotor is compatible with a range of Chevrolet and GMC models, including:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eChevrolet Astro and Safari vans\u003c\/li\u003e\n\u003cli\u003eChevrolet Avalanche 1500\u003c\/li\u003e\n\u003cli\u003eChevrolet Silverado 1500, 1500 Classic, and 2500\u003c\/li\u003e\n\u003cli\u003eChevrolet Suburban 1500 and Tahoe\u003c\/li\u003e\n\u003cli\u003eGMC Sierra 1500, 1500 Classic, and 1500 HD\u003c\/li\u003e\n\u003cli\u003eGMC Yukon and Yukon XL 1500\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon Issues Addressed by DuraGo BR55066\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eWarped or uneven rotors causing brake pulsation\u003c\/li\u003e\n\u003cli\u003eExcessive rotor wear leading to reduced braking efficiency\u003c\/li\u003e\n\u003cli\u003eOverheating and brake fade during heavy use\u003c\/li\u003e\n\u003cli\u003eCorrosion-related rotor surface damage (note: this rotor does not have rust-resistant coating)\u003c\/li\u003e\n\u003cli\u003eIncompatibility with drum-in-hat parking brake systems\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 (0.73 inches) before installation\u003c\/li\u003e\n\u003cli\u003eClean mounting surfaces to prevent rotor runout and vibration\u003c\/li\u003e\n\u003cli\u003eTorque mounting bolts to manufacturer specifications for secure fitment\u003c\/li\u003e\n\u003cli\u003eCheck compatibility with vehicle ABS systems; this rotor does not include an ABS tone ring\u003c\/li\u003e\n\u003cli\u003eInspect brake pads and hardware during rotor replacement for optimal performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDuraGo manufactures the BR55066 rotor to meet or exceed OEM specifications for fit, form, and function.
