Overview of DuraGo BR31141 Disc Brake Rotor

The DuraGo BR31141 is a vented disc brake rotor designed specifically for INFINITI J30 and Q45 models. Crafted from durable cast iron, this rotor provides reliable braking performance tailored to your vehicle's specifications.

  • Material: Cast iron for strength and heat dissipation
  • Vented rotor design to improve cooling
  • Drum-in-hat construction for integrated parking brake compatibility
  • Non-directional brake surface for versatile installation
  • Five mounting bolt holes with precise fitment dimensions

Detailed Product Features and Specifications

The DuraGo BR31141 disc brake rotor features a full cast construction that ensures structural integrity and consistent performance. With an outside diameter of 11.48 inches (291.7 mm) and an overall height of 2.52 inches (64 mm), this rotor matches the exact dimensions required for INFINITI J30 and Q45 vehicles. The nominal thickness is 0.63 inches (16 mm), with a discard thickness of 0.55 inches (14 mm), indicating when replacement is necessary to maintain safe braking. This rotor is vented to enhance heat dissipation during braking, reducing the risk of brake fade under demanding conditions. The drum-in-hat design integrates the parking brake drum within the rotor, eliminating the need for separate components. It includes five mounting bolt holes arranged on a 4.5 inch (114.3 mm) bolt circle diameter, with each hole measuring 0.5 inches (12.8 mm) in diameter. The center hole diameter is 2.68 inches (68.1 mm), ensuring proper hub fitment. This rotor does not include an ABS tone ring and features a non-directional braking surface, allowing installation on either side of the vehicle.
