Detailed Product Description

The DuraGo BR55105 is a full cast, vented disc brake rotor designed to meet the braking demands of Cadillac CTS, STS, and Pontiac Bonneville vehicles. Its cast iron construction provides a balance of strength and thermal conductivity, essential for maintaining braking efficiency under various driving conditions. The vented design allows air to flow between the rotor surfaces, reducing heat buildup and minimizing the risk of brake fade during extended use.

This rotor features a nominal thickness of 1.27 inches (32.2 mm) and a discard thickness of 1.21 inches (30.7 mm), ensuring it meets safety standards for replacement. The 12.72 inch (323 mm) outside diameter and five mounting bolt holes with a 4.53 inch (115 mm) bolt circle diameter provide a precise fit for compatible vehicles. The non-directional brake surface allows for flexible installation without concern for rotor orientation.

Compatible Vehicles and Applications

• Cadillac CTS
• Cadillac STS
• Pontiac Bonneville

This rotor is intended for use in disc brake systems on the front or rear axle, depending on vehicle specifications. It addresses common braking issues such as rotor warping, uneven wear, and reduced braking efficiency.

Common Issues Addressed by DuraGo BR55105

• Brake rotor warping causing vibration during braking
• Excessive rotor wear leading to reduced thickness below safety limits
• Overheating and brake fade from insufficient heat dissipation
• Uneven rotor surface causing noise or pulsation
• Corrosion-related rotor damage (note: this rotor does not include rust-resistant coating)

Installation Notes and Tips

• Verify rotor thickness before installation to ensure it meets minimum discard thickness
• Clean mounting surfaces to prevent uneven rotor seating
• Torque mounting bolts to manufacturer specifications for secure fitment
• Inspect brake pads and replace if worn to prevent premature rotor damage
• Check for ABS tone ring compatibility; this rotor does not include an ABS tone ring

Quality Assurance and Warranty

DuraGo manufactures the BR55105 rotor to meet industry standards for performance and durability. While this rotor does not feature a rust-resistant coating, its full cast iron construction provides reliable service life under normal operating conditions. Warranty coverage details should be confirmed with the original equipment provider or distributor.
