Detailed Product Description

The DuraGo BR901590 is a full cast iron disc brake rotor designed specifically for select Lexus RX models including RX350, RX350L, RX450h, and RX450hL. Its vented construction enhances airflow between the rotor surfaces, helping to dissipate heat generated during braking. This reduces the risk of brake fade and maintains consistent stopping power under demanding conditions. The rotor’s nominal thickness of 0.71 inch (18 mm) ensures structural integrity, while the discard thickness of 0.65 inch (16.5 mm) indicates when replacement is necessary to maintain safe braking performance.

With an outside diameter of 13.31 inches (338 mm) and an overall height of 1.56 inches (39.7 mm), this rotor fits precisely on the specified Lexus models. The 5 mounting bolt holes with a 4.5 inch (114.3 mm) bolt circle diameter provide secure attachment. The non-directional brake surface allows for flexible installation without concern for rotor orientation. This conventional rotor does not include an ABS tone ring and is not cross-drilled or slotted, focusing on durability and consistent performance.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking efficiency due to rotor thinning
• Eliminating noise and vibration from uneven rotor surfaces
• Improving heat dissipation to prevent brake fade on Lexus RX models
• Restoring proper rotor dimensions for safe brake pad contact

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness before installation
• Clean mounting surface to prevent rotor runout and vibration
• Torque mounting bolts to manufacturer specifications for secure fit
• Inspect brake pads and replace if worn to optimize braking performance
• Check for ABS sensor compatibility as this rotor does not include a tone ring
