Detailed Product Description

This Dynamite Friction rotor is a solid disc type designed to meet the braking demands of mid-size sedans such as the Chevrolet Malibu Limited and Buick Regal. The drilled and slotted surface pattern helps to reduce brake fade by allowing gases and heat to escape more efficiently during heavy braking. The zinc silver finish on the rotor hat provides additional protection against rust and corrosion, extending the rotor's service life. With a nominal thickness of 12 mm and a discard thickness of 10.5 mm, this rotor maintains structural integrity under normal operating conditions. The 5-bolt hole pattern with a 120 mm bolt circle diameter ensures compatibility with specified vehicle models.

Compatible Vehicles and Applications

This rotor is compatible with the following makes and models:

• Buick LaCrosse and Regal
• Chevrolet Malibu and Malibu Limited
• Saab 9-5

It is designed to address common braking issues such as:

• Brake fade during extended use
• Uneven pad wear due to heat buildup
• Corrosion and rust on rotor surfaces
• Reduced braking efficiency from glazed rotors
• Vibration or noise caused by rotor surface imperfections

Installation Notes and Tips

When installing the Dynamite Friction 631-45015R rotor, ensure the rotor surface is clean and free of any protective coatings before mounting. The directional slotted and drilled surface must be installed following the correct rotation direction for optimal performance. Verify bolt hole alignment with the vehicle hub and torque lug nuts to manufacturer specifications. It is recommended to inspect brake pads and replace if worn to maintain balanced braking.
