DuraGo BR900576 Disc Brake Rotor - Front Left

Overview of DuraGo BR900576 Disc Brake Rotor

The DuraGo BR900576 disc brake rotor is engineered for reliable braking performance on select Lexus models. Designed with durable cast iron and a vented construction, this rotor supports consistent heat dissipation and long service life for vehicles like the Lexus GS350 and IS300.

• Material: Cast iron for strength and durability
• Vented rotor design to improve cooling
• Nominal thickness: 1.18 inches (30 mm)
• Discard thickness: 1.06 inches (27 mm)
• Outside diameter: 13.15 inches (334 mm)
• Mounting bolt hole quantity: 5 with 4.5 inch (114.3 mm) bolt circle diameter
• Non-directional brake surface for flexible installation
• Conventional rotor type without ABS tone ring

Detailed Product Description

The DuraGo BR900576 is a full cast iron disc brake rotor designed specifically for compatibility with Lexus GS350, GS430, GS450h, GS460, IS200t, IS300, and IS350 models. Its vented construction enhances heat dissipation during braking, reducing the risk of rotor warping under heavy use. The rotor measures 13.15 inches in outside diameter and maintains a nominal thickness of 1.18 inches, ensuring proper fit and performance within the brake system. The 5-bolt mounting pattern with a 4.5-inch bolt circle diameter matches factory specifications for secure installation. This rotor features a non-directional braking surface, allowing it to be installed on either side of the vehicle without concern for directional wear patterns. It does not include an ABS tone ring, so it is intended for vehicles with separate ABS sensor components.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Lexus GS and IS series vehicles
• Addresses brake pulsation caused by uneven rotor thickness
• Improves braking consistency by restoring proper rotor dimensions
• Helps reduce brake noise associated with damaged rotors
• Supports safe braking performance under normal and heavy driving conditions

Installation Notes and Tips

• Verify rotor thickness before installation to ensure it meets minimum discard thickness of 1.06 inches
• Clean mounting surface and hub to prevent rotor runout
• Torque mounting bolts to manufacturer specifications for secure fitment
• Inspect brake pads and replace if worn to maintain optimal braking performance
• Check for compatibility with vehicle ABS system as this rotor does not include an ABS tone ring

Quality Assurance and Warranty

DuraGo manufactures the BR900576 rotor to meet or exceed OEM standards for fit, form, and function. The cast iron construction and vented design provide durability and heat management consistent with factory requirements. While specific warranty details should be confirmed at the point of purchase, DuraGo typically offers limited warranties covering defects in materials and workmanship to ensure customer confidence in product reliability.
