Detailed Product Description

This Beck Arnley disc brake rotor (part number 083-3178) is engineered to meet the specifications required for Mitsubishi Lancer and Outlander vehicles. The rotor is solid rather than vented, which suits certain brake system designs where heat dissipation requirements differ. With a 5-lug wheel pattern and a bolt pattern of 114.3 mm, it matches the factory specifications for these models. The rotor's dimensions, including a 302 mm outer diameter and 10 mm surface thickness, provide a stable braking surface. The 12.7 mm lug stud hole diameter and 80 mm center hole diameter ensure proper mounting and alignment on the hub assembly. The rotor height of 59 mm and hub outer diameter of 204 mm are designed to fit precisely within the brake caliper and wheel assembly.

Applications and Problem Solving

• Replacement for worn or warped rotors on Mitsubishi Lancer and Outlander
• Addresses brake pulsation caused by uneven rotor surfaces
• Restores proper braking performance and pedal feel
• Suitable for vehicles with 5-lug, 114.3 mm bolt pattern wheels
• Helps prevent brake noise related to rotor surface irregularities

Installation Notes and Tips

Ensure the rotor surface is clean and free of rust or debris before installation. Verify the rotor thickness meets or exceeds the minimum thickness of 8 mm to maintain safe braking performance. Use proper torque specifications for lug nuts to avoid rotor warping. It is recommended to inspect brake pads and replace them if worn when installing new rotors. Follow manufacturer guidelines for bedding in new rotors to optimize braking efficiency.
