  • Non-directional brake surface for versatile installation
  • Compatible with Cadillac CTS and STS models

Durable Cast Iron Construction and Precise Dimensions

This DuraGo disc brake rotor features a full cast iron construction, providing a solid and reliable braking surface. The vented design helps reduce heat buildup during braking, which can improve rotor longevity and maintain consistent performance. With an outside diameter of 12.6 inches (320 mm) and an overall height of 1.9 inches (48.2 mm), the rotor fits precisely on compatible Cadillac CTS and STS vehicles. The rotor’s nominal thickness is 1.02 inches (26 mm), with a discard thickness of 0.94 inches (24 mm), ensuring clear guidelines for replacement timing.

Compatible Applications and Part Number Details

The DuraGo BR900372 disc brake rotor is specifically designed for use on Cadillac CTS and STS models. It features a drum-in-hat design and includes 5 mounting bolt holes with a bolt circle diameter of 4.53 inches (115 mm). The center hole diameter measures 2.78 inches (70.7 mm), and the mounting bolt hole diameter is 0.52 inches (13.2 mm). This rotor does not include an ABS tone ring and has a non-directional brake surface, allowing for flexible installation options.

Common Issues Addressed by This Brake Rotor

  • Reduced braking efficiency due to worn or warped rotors
  • Excessive brake noise or vibration during stops
  • Overheating caused by insufficient heat dissipation
  • Uneven brake pad wear linked to rotor surface irregularities
  • Corrosion-related rotor damage (note: this rotor does not have rust-resistant coating)

Installation Notes and Tips

  • Ensure the rotor thickness is above the discard thickness of 0.94 inches (24 mm) before installation
  • Clean the rotor surface to remove any protective coatings or debris prior to mounting
  • Verify compatibility with your specific Cadillac CTS or STS model year
  • Torque mounting bolts to manufacturer specifications to avoid rotor warping
  • Check brake pads for wear and replace if necessary during rotor installation
