• Vented rotor design to improve cooling and reduce brake fade
• Nominal thickness of 1.27 inches (32.3 mm) with discard thickness at 1.21 inches (30.7 mm)
• Overall height of 2.07 inches (52.7 mm) and outside diameter of 11.69 inches (297 mm)
• 6 mounting bolt holes with a bolt circle diameter of 4.53 inches (115 mm)
• Non-directional brake surface for versatile installation
• Conventional full cast construction without rust-resistant coating

Durable Construction and Precise Fitment Details

The DuraGo BR55118 rotor is made from full cast iron, providing a solid and reliable braking surface. Its vented design allows air to flow between the rotor surfaces, helping to dissipate heat during braking and reduce the risk of brake fade. With a nominal thickness of 1.27 inches and a discard thickness of 1.21 inches, this rotor meets specifications for safe replacement. The rotor’s 6 mounting bolt holes and 4.53-inch bolt circle diameter ensure proper fitment on compatible vehicles. This rotor does not include an ABS tone ring and features a non-directional braking surface, allowing for flexible installation on the front or rear axle as required.

Compatible Vehicles and Applications

This disc brake rotor is compatible with the following vehicles:

• Buick Montana
• Chevrolet Relay
• Pontiac Terraza
• Saturn Uplander

It is designed to replace worn or damaged rotors, restoring braking efficiency and safety for these specific models.

Common Issues Addressed by This Rotor

• Brake pulsation or vibration caused by warped rotors
• Reduced braking performance due to worn rotor thickness
• Overheating and brake fade from insufficient heat dissipation
• Uneven brake pad wear linked to rotor surface irregularities
• Noise or squealing related to rotor surface damage

Installation Notes and Tips

• Ensure the rotor thickness is above the discard thickness before installation
• Clean the rotor surface to remove any protective coatings or contaminants
• Check mounting bolt holes and hub surface for debris or damage
• Torque mounting bolts to manufacturer specifications to avoid rotor warping
• Inspect brake pads and replace if worn to ensure optimal rotor performance
