Its solid, full cast iron construction ensures consistent braking performance under normal driving conditions. The rotor’s nominal thickness of 0.47 inches (12 mm) and discard thickness of 0.39 inches (10 mm) provide a clear service life indicator to maintain safe braking. With a 5-bolt mounting pattern and precise dimensions, this rotor fits securely and aligns properly with the vehicle’s braking system. The non-directional braking surface allows for flexible installation without concern for rotor orientation. This rotor does not include rust-resistant coating or ABS tone ring, so it is best suited for applications where these features are not required.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Issues Addressed\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on Acura RL models\u003c\/li\u003e\n\u003cli\u003eResolves brake pulsation caused by uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eAddresses reduced braking efficiency due to rotor thickness below discard limits\u003c\/li\u003e\n\u003cli\u003eEliminates noise and vibration from damaged or scored rotors\u003c\/li\u003e\n\u003cli\u003eRestores proper rotor dimensions for safe brake pad contact\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 and hub mounting area to prevent uneven wear\u003c\/li\u003e\n\u003cli\u003eTorque mounting bolts to manufacturer specifications for secure fitment\u003c\/li\u003e\n\u003cli\u003eCheck compatibility with vehicle ABS system as this rotor does not include an ABS tone ring\u003c\/li\u003e\n\u003cli\u003eInspect brake pads and replace if worn to optimize braking performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDuraGo brake rotors are manufactured to meet or exceed OEM specifications for fit, form, and function.
