About StopTech Sport Cross-Drilled Disc Brake Rotors

The StopTech Sport Cross-Drilled Disc Brake Rotors line is designed to offer improved thermal management and braking consistency for performance-oriented street and light track use. The cross-drilled surface pattern enhances ventilation and helps evacuate gases and debris from the pad surface, while the vented rotor design promotes airflow to reduce heat soak. The coated hat finish provides corrosion resistance, extending rotor life and maintaining appearance. This rotor features a floating disc mounting system that allows slight movement between the rotor and hub, reducing the risk of warping and improving overall brake feel.

Detailed Product Description

This disc brake rotor, part number 128.40018L, is specifically manufactured for Honda Accord and Prelude models. It features a 10.315-inch (262 mm) outside diameter and a nominal thickness of 0.827 inches (21 mm), with a discard thickness of 0.748 inches (19 mm) to indicate when replacement is necessary. The rotor is vented with straight vanes to optimize heat dissipation during braking. The hat section is coated to resist corrosion, and the rotor includes four mounting bolt holes arranged in a 100 mm (3.937 inch) bolt circle diameter. The center hole diameter measures 2.524 inches (64.1 mm), and the rotor weighs approximately 12 pounds (5.45 kg). This rotor does not include ABS tone rings or bearings.

Common Applications and Problem Solving

• Replaces worn or warped rotors on Honda Accord and Prelude models
• Improves brake cooling to reduce fade during spirited driving
• Addresses rotor corrosion issues with coated hat finish
• Reduces brake noise and vibration caused by uneven rotor surfaces
• Enhances braking consistency under heavy load or repeated stops

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness before installation
• Clean rotor surface with brake cleaner to remove any protective coatings
• Use proper torque specifications for mounting bolts on Honda Accord or Prelude
• Inspect brake pads and calipers for wear or damage during installation
• Perform a bed-in procedure after installation to optimize brake pad contact
