Its vented construction enhances cooling by allowing air to flow between the rotor faces, which helps prevent brake fade during extended use. The rotor measures 13.31 inches (338 mm) in outside diameter and 2.87 inches (73 mm) in overall height, fitting precisely on BMW 135i and 135is models. The nominal thickness is 1.02 inches (26 mm), with a discard thickness of 0.96 inches (24.4 mm), indicating when replacement is necessary to maintain safe braking performance.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cp\u003eThis DuraGo disc brake rotor is compatible with BMW 135i and 135is vehicles, providing a direct replacement for worn or damaged rotors. It is designed for drivers seeking a reliable rotor that meets OEM specifications without additional features like cross-drilling or slotted surfaces. The non-directional brake surface allows for flexible installation without concern for rotor orientation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eReplaces worn or warped rotors causing vibration or noise\u003c\/li\u003e\n\u003cli\u003eAddresses reduced braking efficiency due to rotor thinning\u003c\/li\u003e\n\u003cli\u003eEliminates brake pulsation from uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eRestores proper rotor dimensions for safe braking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eWhen installing the DuraGo BR900724 rotor, ensure the mounting surface is clean and free of rust or debris to promote proper fitment. Use the correct torque specifications for the five mounting bolts on the 4.72 inch (120 mm) bolt circle diameter. Since this rotor does not include an ABS tone ring, verify compatibility with your vehicle’s ABS system before installation. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDuraGo manufactures this rotor to meet or exceed OEM standards for fit, form, and function. The composite construction and vented design contribute to consistent braking performance and durability. While specific warranty details are not provided, DuraGo products typically come with a limited warranty against defects in materials and workmanship.
