Detailed Product Description

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor 127.42029L is a vented rotor designed to optimize braking efficiency for Nissan 720, D21, Frontier, Pathfinder, and Pickup vehicles. Its cross-drilled and slotted surface helps to reduce brake fade by allowing gases and dust to escape, while also improving water dispersion in wet conditions. The rotor’s vented design with straight vanes promotes airflow, which aids in heat dissipation during heavy braking. The coated hat finish provides corrosion resistance, helping maintain rotor integrity over time. With a nominal thickness of 1.024 inches (26.000 mm) and discard thickness of 0.945 inches (24.000 mm), this rotor meets strict specifications for safe and reliable braking performance. The rotor mounts behind the hub using six bolts with a 1.250 thread pitch, ensuring a secure fit. Weighing approximately 6.9 lbs (3.14 kgs), it balances durability and weight for effective braking without excessive unsprung mass.

Applications and Problem Solving

• Reduces brake fade during aggressive driving or towing
• Improves braking response in wet or dusty conditions
• Minimizes rotor warping caused by excessive heat buildup
• Helps maintain consistent brake pad contact and performance
• Prevents corrosion-related rotor damage with coated hat finish

Installation Notes and Tips

• Compatible with front brake systems on Nissan 720, D21, Frontier, Pathfinder, and Pickup models
• Ensure rotor thickness is above discard thickness before installation
• Use proper torque specifications for the 6 mounting bolts with 1.250 thread pitch
• Inspect brake pads and hardware for wear during rotor replacement
• Clean rotor surface before installation to remove any protective coatings or debris
