• Drum-in-hat construction for integrated parking brake function
• Outside diameter of 12.08 inches (306.8 mm)
• Nominal thickness of 0.63 inches (16.1 mm) with discard thickness at 0.59 inches (15 mm)
• Five mounting bolt holes with a 4.5 inch (114.3 mm) bolt circle diameter
• Non-directional brake surface for flexible installation
• Overall height of 2.64 inches (67.1 mm)

Detailed Product Description

The DuraGo BR31153 is a full cast, vented disc brake rotor designed specifically for compatibility with Lexus GS300, LS400, SC300, SC400, and Toyota Supra models. Its cast iron material provides a solid foundation for effective braking, while the vented design helps dissipate heat generated during braking to reduce the risk of rotor warping. The drum-in-hat construction integrates a parking brake drum, eliminating the need for a separate component and simplifying maintenance. This rotor features a non-directional braking surface, allowing for installation on either side of the vehicle without performance loss. The precise dimensions, including a 12.08 inch outside diameter and 0.63 inch nominal thickness, ensure proper fit and function within the specified vehicle brake systems.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking efficiency due to rotor thinning
• Resolving noise issues related to uneven rotor surfaces
• Upgrading to a vented rotor for improved heat management
• Restoring proper parking brake function with drum-in-hat design

Installation Notes and Tips

When installing the DuraGo BR31153 rotor, ensure the mounting surface is clean and free of debris to prevent misalignment. Verify the rotor thickness before installation to confirm it meets or exceeds the discard thickness of 0.59 inches (15 mm). Use proper torque specifications on the five mounting bolts to secure the rotor firmly. Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system. It is recommended to replace brake pads simultaneously to maintain optimal braking performance.
