Durable Cast Iron Disc Brake Rotor for Cadillac CTS and STS

The DuraGo BR900372-01 disc brake rotor is engineered to provide reliable braking performance for Cadillac CTS and STS models. Featuring a vented, drum-in-hat design with rust-resistant coating, this rotor balances durability and heat dissipation for consistent stopping power.

  • Constructed from full cast iron for strength and longevity
  • Vented rotor design improves heat dissipation during braking
  • Rust-resistant coating helps prevent corrosion and extends rotor life
  • Drum-in-hat type rotor with 5 mounting bolt holes for secure fitment
  • Non-directional brake surface compatible with various brake pad types

Technical Specifications and Design Features

The DuraGo BR900372-01 rotor is made from cast iron, known for its durability and heat resistance. It features a nominal thickness of 1.02 inches (26 mm) and a discard thickness of 0.94 inches (24 mm), ensuring safe replacement intervals. The rotor's outside diameter measures 12.6 inches (320 mm), with an overall height of 1.9 inches (48.2 mm). This vented rotor design enhances airflow to reduce brake fade under heavy use. The drum-in-hat construction integrates a drum brake surface, providing compatibility with rear brake systems that combine disc and drum functions. The rotor includes five mounting bolt holes with a bolt circle diameter of 4.53 inches (115 mm) and a center hole diameter of 2.78 inches (70.7 mm). The non-directional brake surface allows for flexible installation without concern for rotor orientation.

Compatible Vehicles and Applications

  • Designed specifically for Cadillac CTS models requiring a 320 mm vented disc brake rotor
  • Compatible with Cadillac STS vehicles equipped with drum-in-hat rear brake rotors
  • Ideal for replacing worn or damaged rotors to restore braking efficiency
  • Suitable for drivers experiencing brake noise, vibration, or reduced stopping power
  • Addresses rotor wear issues such as scoring, warping, and corrosion

Installation Notes and Tips

When installing the DuraGo BR900372-01 rotor, ensure the mounting surface is clean and free of debris to promote proper rotor seating. Verify the rotor thickness before installation to confirm it meets minimum specifications. Since this rotor is non-directional, it can be installed on either side without affecting performance. Use the correct torque specifications for the 5 mounting bolts to avoid rotor distortion. This rotor does not include an ABS tone ring, so confirm compatibility with your vehicle's ABS system.
