ADVICS L6F337U Disc Brake Rotor - Front

ADVICS Front Vented Brake Rotor

The ADVICS L6F337U is an ultra-premium OE replacement disc brake rotor built for front brake service on select Buick and Pontiac applications. It uses high carbon steel and a vented design to promote airflow through the rotor for more consistent braking performance.

Compatible with 2005-2009 Buick Allure front, 2005-2009 Buick LaCrosse front, and 2004-2008 Pontiac Grand Prix front, this rotor is built to match the dimensions and fitment requirements of the original brake setup.

Key Features

• High carbon steel construction for OE-style rotor strength and thermal stability
• Vented rotor design to help move air through the braking surface
• Non-directional brake surface finish for even pad contact during break-in
• Smooth surface type for consistent rotor-to-pad interaction
• Front disc brake rotor application for select Buick and Pontiac models
• Part number L6F337U for easy cross-reference and ordering

Product Details

ADVICS positions the Ultra-Premium OE Replacement line as a direct-fit brake solution for drivers who want factory-style dimensions and material quality. The L6F337U rotor measures 11.705 inches in outside diameter, 2.039 inches in overall height, and 1.26 inches in nominal thickness, with a 70.6 mm center hole diameter and a 5-lug bolt pattern on a 118.0 mm bolt circle. The discard thickness is 1.209 inches. This rotor does not include an ABS tone ring.

This part cross-references Bosch 25010562 for the same application. If you are replacing worn front rotors on a Buick Allure, Buick LaCrosse, or Pontiac Grand Prix, ADVICS L6F337U provides an OE-style replacement built around the original fitment dimensions.

Common Brake Issues This Rotor Can Address

• Brake pulsation caused by rotor wear or thickness variation
• Reduced braking smoothness from scored or uneven rotor surfaces
• Noise related to worn front brake rotors
• Heat buildup from a rotor that no longer dissipates air effectively
• Service replacement for front rotors at or near discard thickness

Installation Notes and Tips

Verify rotor dimensions, hub fit, and bolt pattern before installation. Clean the hub mounting surface thoroughly to help prevent lateral runout and brake pulsation after service. Follow proper brake bedding procedures after installing new pads and rotors, and inspect pads, calipers, and hardware for wear before reassembly.
