DuraGo BR5581 Disc Brake Rotor - Front

Overview of DuraGo BR5581 Disc Brake Rotor

The DuraGo BR5581 disc brake rotor is engineered for reliable braking performance on select Saturn models. Designed with durable cast iron and a vented construction, this rotor supports effective heat dissipation and consistent stopping power for vehicles like the Saturn SC, SL, and SW series.

• Material: Cast iron for strength and durability
• Vented rotor design to improve heat dissipation
• Nominal thickness of 0.71 inches (18 mm) with discard thickness at 0.62 inches (15.8 mm)
• Overall diameter of 9.84 inches (250 mm) suitable for specific Saturn models
• Four mounting bolt holes with a 3.94 inch (100 mm) bolt circle diameter
• Non-directional brake surface for versatile installation
• Conventional rotor type without ABS tone ring

Detailed Product Description

The DuraGo BR5581 is a full cast, vented disc brake rotor constructed from cast iron, providing a balance of durability and thermal management. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking and helping to maintain consistent brake performance. With a nominal thickness of 0.71 inches (18 mm) and a discard thickness of 0.62 inches (15.8 mm), this rotor meets the specifications required for safe and effective braking on compatible Saturn vehicles.

Measuring 9.84 inches (250 mm) in outside diameter and featuring four mounting bolt holes spaced on a 3.94 inch (100 mm) bolt circle, the BR5581 rotor is designed for direct replacement on Saturn SC, SC1, SC2, SL, SL1, SL2, SW1, and SW2 models. The rotor’s non-directional brake surface allows for flexible installation without concern for rotation direction, and the conventional rotor design fits standard braking systems without integrated ABS tone rings.

Compatible Vehicles and Applications

This DuraGo disc brake rotor is compatible with the following Saturn models:

• Saturn SC, SC1, SC2
• Saturn SL, SL1, SL2
• Saturn SW1, SW2

It is intended for use in front or rear disc brake systems where a vented, conventional rotor is specified.

Common Issues Addressed by DuraGo BR5581 Rotor

• Brake pulsation or vibration due to warped rotors
• Reduced braking efficiency from worn or thin rotors
• Overheating and brake fade during extended braking
• Uneven brake pad wear caused by rotor surface irregularities
• Noise or squealing related to rotor surface condition

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness before installation
• Clean rotor surface to remove any protective coatings or debris
• Check mounting bolt hole alignment with vehicle hub for proper fit
• Torque mounting bolts to manufacturer specifications
• Inspect brake pads and calipers during rotor replacement for optimal performance
