Technical Details and Specifications

This disc brake rotor features a vented design to improve airflow and cooling during braking. The rotor’s nominal thickness is 20 mm, with a discard thickness of 18 mm, ensuring safe replacement intervals. The surface is both drilled and slotted, which helps reduce brake fade and maintain consistent stopping power. The rotor’s hat is finished in zinc silver, providing corrosion resistance, while the disc finish is plain. It includes six bolt holes with a 108 mm bolt circle diameter and a center hole diameter of 86 mm, matching the factory specifications for Mazda B2000, B2200, and B2600 models.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Mazda B2000, B2200, and B2600
• Improves heat dissipation to reduce brake fade during heavy use
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps maintain consistent braking performance in wet or dusty conditions
• Prevents rust and corrosion with zinc silver hat finish and coating

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 18 mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Use proper torque specifications for the six lug bolts with a 108 mm bolt circle diameter. Verify compatibility with Mazda B2000, B2200, and B2600 models to ensure proper fitment. Directional rotors must be installed following the indicated rotation direction for optimal performance.
