Detailed Product Description

The DuraGo BR901278 disc brake rotor is constructed from full cast iron, providing a solid and durable braking surface suitable for the heavy-duty requirements of Ram ProMaster vans. 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.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Ram ProMaster 1500, 2500, and 3500
• Addresses brake pulsation caused by uneven rotor surfaces
• Restores braking efficiency lost due to rotor thickness below discard limits
• Eliminates noise and vibration from damaged or scored rotors
• Supports safe parking brake operation with integrated drum-in-hat design

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (0.78 inches) before installation
• Clean mounting surfaces to prevent rotor runout and vibration
• Torque mounting bolts to manufacturer specifications for secure fitment
• Check compatibility with ABS systems as this rotor does not include an ABS tone ring
• Inspect brake pads and hardware during rotor replacement for optimal performance
