Centric 320.65077F Disc Brake Rotor - Front

Centric GCX Full Coated Front Rotor

The Centric GCX Elemental Protection Disc Brake Rotor, part number 320.65077F, is a front vented rotor built for OE-style braking performance and added resistance to rust and corrosion. It is a strong match for drivers looking for a 261 mm front disc rotor for Ford Ranger, Mazda B2300, Mazda B3000, or Mazda B4000 applications.

Centric’s GCX Full Coating line uses an RS200 protective finish on non-mating surfaces to help preserve appearance and surface integrity over time. The 320.65077F is also built with application-specific metallurgy and coating patterns to align with the brake pad friction type and the vehicle’s OEM rotor profile.

Product Details

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating line is engineered for drivers who want a direct replacement rotor with corrosion protection built in. This rotor measures 261.0 mm in outside diameter, 26.1 mm nominal thickness, and 24.5 mm discard thickness, with an overall height of 108.0 mm and a 70.4 mm center hole diameter. It uses a 114.3 mm bolt circle with five lug holes and a hub-and-rotor mounting style. The rotor weighs 20.0 lbs and includes an ABS tone ring.

Compatible With 1998-2002 Ford Ranger, front; 2003-2010 Mazda B2300, front; 2003-2004 Mazda B3000, front; 2006-2007 Mazda B3000, front; and 1998-2000 Mazda B4000, front. This part number, 320.65077F, is a practical OE-style replacement for front brake service on these vehicles.

Common Brake Issues It Can Address

• Rust buildup on exposed rotor surfaces
• Brake pulsation caused by worn or uneven rotors
• Reduced braking consistency from rotor wear
• Noise related to rotor surface condition
• Loss of rotor appearance from corrosion exposure

Installation Notes

Verify rotor diameter, thickness, bolt pattern, and center bore before installation. This rotor is listed for front position use only and should be matched to the vehicle’s brake pad condition and hardware inspection during service. Confirm ABS tone ring requirements and compare the existing rotor dimensions to the specifications above before completing the repair.

For search relevance, this rotor is commonly selected for Ford Ranger front brake rotor replacement and Mazda B2300 front disc brake service. It is also a fitment match for Mazda B3000 and Mazda B4000 front brake applications where a 261 mm vented rotor is specified.
