Centric Premium Disc Brake Rotors Product Line

The Centric Premium Disc Brake Rotors line focuses on delivering rotors that meet or exceed OEM specifications. This product line emphasizes precision manufacturing, corrosion-resistant coatings, and vented rotor designs to enhance braking efficiency and rotor longevity. The 120.45039 rotor is part of this line, offering a vented and coated rotor solution tailored for specific Ford, Mazda, and Mercury models.

Detailed Product Description

This disc brake rotor features a vented design that helps dissipate heat more effectively during braking, reducing the risk of brake fade. The rotor has a nominal thickness of 22 mm and a discard thickness of 20 mm, ensuring it maintains structural integrity throughout its service life. The coated hat finish provides protection against rust and corrosion, extending the rotor's usable life. With an outside diameter of 234.7 mm and an overall height of 45 mm, this rotor fits securely on vehicles requiring a 4-bolt mounting pattern with a 100 mm bolt circle diameter. The floating mounting type allows for slight movement to accommodate thermal expansion and improve braking consistency. The smooth surface type ensures even pad wear and reliable stopping power.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing rotor corrosion and surface rust issues
• Improving heat dissipation to reduce brake fade on daily drivers
• Restoring proper rotor thickness for safe braking performance
• Ensuring compatibility with ABS systems where tone rings are not required

Installation Notes and Tips

• Verify vehicle compatibility with Ford Escort, Mazda Protege, or Mercury Tracer before installation
• Check rotor thickness and discard limits to ensure replacement necessity
• Clean hub surface before mounting to prevent rotor runout
• Use proper torque specifications on the 4 mounting bolts with 100 mm bolt circle diameter
• Inspect brake pads for wear and replace if necessary to ensure optimal rotor performance
