Product Line Details: Power Stop - Front Genuine Geomet Coated Rotor

This rotor is part of the Power Stop - Front Genuine Geomet Coated Rotor line, which focuses on providing rotors with a factory-style Geomet coating. This coating enhances rust resistance without compromising braking performance, making it suitable for standard replacement needs. The full cast and vented design supports effective heat management, helping maintain rotor integrity during regular driving conditions.

Technical Description and Specifications

The JBR1915EVC rotor features a full cast construction that ensures structural integrity and consistent performance. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking. The Geomet coating provides a protective layer against rust and corrosion, extending the rotor's service life. With a nominal thickness of 24.9 mm and a discard thickness of 23.0 mm, this rotor meets standard replacement criteria. The rotor measures 279.8 mm in outside diameter and includes a 114.3 mm mounting bolt hole circle diameter with five lug holes, matching Mazda 3 front brake specifications. The smooth surface type ensures even brake pad wear and reliable stopping power.

Common Applications and Problem Solving

• Replacement for worn or warped front rotors on Mazda 3 models
• Addresses brake pulsation caused by uneven rotor surfaces
• Prevents rust-related rotor degradation in humid or salty environments
• Improves heat dissipation to reduce brake fade during extended use
• Restores braking performance after rotor thickness falls below safe limits

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify that the rotor thickness is within the discard limits (minimum 23.0 mm) to maintain safety and performance. Use proper torque specifications for mounting bolts to avoid rotor warping. This rotor does not include an ABS tone ring, so confirm compatibility with your vehicle's ABS system. It is recommended to replace brake pads simultaneously for optimal braking results.
