Its vented design enhances heat dissipation during braking, reducing the risk of brake fade under load or extended use. The rotor features a nominal thickness of 0.87 inches (22 mm) and a discard thickness of 0.78 inches (19.9 mm), ensuring clear service limits for maintenance. With an outside diameter of 11.81 inches (300 mm) and an overall height of 3.15 inches (80 mm), this rotor fits precisely on the specified Ram ProMaster models. The drum-in-hat construction integrates the parking brake drum within the rotor, streamlining installation and maintenance. This rotor does not include an ABS tone ring and has a non-directional braking surface, allowing for flexible installation orientation.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on Ram ProMaster 1500, 2500, and 3500\u003c\/li\u003e\n\u003cli\u003eAddresses brake pulsation caused by uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eRestores braking efficiency lost 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\u003eSupports safe parking brake operation with integrated drum-in-hat design\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 (0.78 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 ABS systems as 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 BR901278 rotor to meet or exceed OEM specifications for Ram ProMaster 1500, 2500, and 3500 vehicles.
