Product Details and Specifications

This Centric disc brake rotor features a vented design with straight vanes that help dissipate heat efficiently, reducing the risk of brake fade during extended use. The rotor's nominal thickness is 1.185 inches (30.100 mm), with a discard thickness of 1.120 inches (28.450 mm), indicating when replacement is necessary. The smooth surface type ensures even brake pad wear and reliable stopping power. With an outside diameter of 10.720 inches (272.300 mm) and an overall height of 4.831 inches (122.700 mm), this rotor fits Mercury Montego vehicles equipped with a 5-lug wheel pattern and a mounting bolt hole circle diameter of 4.500 inches (114.300 mm). The stud thread diameter measures 0.500 inches (12.7 mm), compatible with standard lug nuts.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing rotor thickness below manufacturer discard limits
• Improving heat dissipation to reduce brake fade during heavy braking
• Restoring smooth braking performance and reducing noise
• Ensuring proper fitment for Mercury Montego brake systems

Installation Notes and Tips

Ensure the rotor mounting surface and hub are clean and free of rust or debris before installation. Verify the rotor thickness to confirm it meets minimum specifications. This rotor mounts to the hub and requires a 5-lug wheel pattern with a 4.500 inch bolt circle diameter. Use proper torque specifications for lug nuts and mounting bolts to avoid rotor warping. Note that this rotor does not include bearings or ABS tone rings, so verify compatibility with your vehicle's braking system.
