Technical Description and Specifications

The JBR1930EVC rotor features a full cast construction that ensures structural integrity under demanding braking conditions. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup and minimizing brake fade. The smooth surface finish promotes even brake pad wear and consistent braking response. With a nominal thickness of 1.00 inch (25.00 mm) and a discard thickness of 0.90 inch (23.00 mm), this rotor meets standard replacement specifications. The rotor measures 12.80 inches (325.70 mm) in outside diameter and includes a mounting bolt hole circle diameter of 4.50 inches (114.30 mm) with 5 lug holes, ensuring compatibility with the front brake assembly of the Mazda CX-50.

Common Applications and Problem Solving

• Replacement for worn or warped front rotors on Mazda CX-50
• Addresses brake noise caused by uneven rotor surfaces
• Improves braking performance affected by rust or corrosion
• Helps reduce brake fade during extended or heavy braking
• Restores proper rotor thickness for safe braking operation

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness is within the discard limits to maintain safety standards. 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 performance.
