Technical Specifications and Features

This disc brake rotor is vented to allow air circulation between the rotor faces, which helps dissipate heat generated during braking. The rotor’s surface is both drilled and slotted, which aids in removing brake dust, gases, and water from the contact area, improving braking consistency. The rotor has a nominal thickness of 18 mm and a discard thickness of 17 mm, indicating when replacement is necessary to maintain safety. The zinc silver hat finish offers rust resistance, protecting the rotor’s central mounting area. With 4 bolt holes and a bolt circle diameter of 87 mm, this rotor fits securely on compatible Toyota Corolla models.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Toyota Corolla vehicles
• Improves heat dissipation to reduce brake fade during extended use
• Helps maintain consistent braking performance in wet or dusty conditions
• Addresses rotor corrosion issues with rust-resistant coating
• Enhances brake pad contact through slotted and drilled surface design

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 17 mm before installation. Clean the rotor surface to remove any protective coatings or debris prior to mounting. Verify bolt hole alignment with the vehicle’s hub using the 4 bolt holes and 87 mm bolt circle diameter. Proper torque specifications should be followed to secure the rotor. It is recommended to inspect brake pads and hardware during rotor replacement for optimal braking system performance.
