Detailed Product Description

The DuraGo BR31303 disc brake rotor is engineered for Acura RL vehicles requiring a drum-in-hat type rotor. Its solid, full cast iron construction ensures consistent braking performance under normal driving conditions. The rotor’s nominal thickness of 0.47 inches (12 mm) and discard thickness of 0.39 inches (10 mm) provide a clear service life indicator to maintain safe braking. With a 5-bolt mounting pattern and precise dimensions, this rotor fits securely and aligns properly with the vehicle’s braking system. The non-directional braking surface allows for flexible installation without concern for rotor orientation. This rotor does not include rust-resistant coating or ABS tone ring, so it is best suited for applications where these features are not required.

Common Applications and Issues Addressed

• Replacement for worn or warped rotors on Acura RL models
• Resolves brake pulsation caused by uneven rotor surfaces
• Addresses reduced braking efficiency due to rotor thickness below discard limits
• Eliminates noise and vibration from damaged or scored rotors
• Restores proper rotor dimensions for safe brake pad contact

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness before installation
• Clean rotor surface and hub mounting area to prevent uneven wear
• Torque mounting bolts to manufacturer specifications for secure fitment
• Check compatibility with vehicle ABS system as this rotor does not include an ABS tone ring
• Inspect brake pads and replace if worn to optimize braking performance
