The rotors have a discard thickness of 1.02 mm and 26.00 mm, indicating when replacement is necessary to maintain safety standards. The overall height varies from 2.70 mm to 67.50 mm, and the outside diameter measures 12.60 inches (319.00 mm), matching OEM specifications for proper fitment. The mounting bolt hole circle diameter is 139.70 mm with six lug holes, compatible with the specified Toyota models.

Applications and Problem Solving

• Replaces worn or warped front brake rotors on Toyota 4Runner, FJ Cruiser, and Tacoma
• Addresses brake fade caused by overheating during heavy braking
• Reduces rust and corrosion buildup on rotors for longer service life
• Improves braking response and pedal feel with slotted and drilled design
• Helps eliminate brake noise and vibration associated with rotor surface issues

Installation Notes and Tips

Ensure the vehicle is securely lifted and supported before removing the existing front rotors. Clean the hub surface to remove rust and debris for proper rotor seating. Verify the rotor thickness before installation to confirm it meets or exceeds the discard thickness. Use a torque wrench to tighten lug nuts to manufacturer specifications. It is recommended to replace brake pads when installing new rotors to optimize braking performance.
