Technical Specifications and Features

The JBR1116EVC rotor is a solid disc type with an outside diameter of 279.80 mm (11.00 inches), suitable for rear brake applications on the Mazda 3. It has a nominal thickness of 10.90 mm and a discard thickness of 9.00 mm, ensuring safe replacement intervals. The rotor’s overall height measures approximately 40.70 mm, and it mounts using a 5-lug pattern with a bolt hole circle diameter of 114.30 mm. The Geomet coating provides a durable, rust-resistant surface that helps maintain rotor condition in various driving environments.

Common Applications and Problem Solving

• Replacement for worn or warped rear rotors on Mazda 3 models
• Addresses rotor corrosion and rust buildup issues
• Improves braking consistency by restoring proper rotor thickness
• Eliminates brake noise caused by uneven rotor surfaces
• Prevents premature rotor failure due to environmental exposure

Installation Notes and Tips

When installing the Power Stop JBR1116EVC rotor, ensure the mounting surface is clean and free of debris. Verify the rotor thickness before installation to confirm it meets or exceeds the discard thickness of 9.00 mm. Use proper torque specifications for the 5-lug mounting pattern with a 114.30 mm bolt circle diameter. It is recommended to replace brake pads simultaneously to ensure optimal braking performance and rotor longevity.

Quality Assurance and Warranty

Power Stop rotors are manufactured to meet OEM standards and undergo rigorous quality control to ensure durability and performance. The Geomet coating enhances corrosion resistance, contributing to longer rotor life. Warranty details should be confirmed with the product documentation or manufacturer, as coverage may vary.
