Common Uses

• Replacing a worn or warped front brake rotor
• Reducing brake fade from heat buildup during repeated stops
• Improving wet-weather braking consistency
• Addressing pad glazing and uneven pad contact
• Restoring braking performance on a Honda Civic front brake service

Installation Notes

Verify rotor dimensions, bolt pattern, and hub fitment before installation. This rotor mounts behind the hub and does not include ABS tone ring or bearings. Use new pads only if the existing pads are worn, glazed, or unevenly matched to the rotor surface, and follow the vehicle manufacturer’s brake service procedure.

Quality Assurance

StopTech uses a coated finish and high carbon metallurgy in most applications to support corrosion resistance, quieter operation, and improved crack resistance. The rotor is built as a direct replacement part for stock caliper systems and factory brake hardware layouts.
