Product Line Details: Gray Armor-Plate, Premium

The Gray Armor-Plate, Premium line by Perfect Stop focuses on durable rotors with enhanced surface protection and vented design. This product line aims to provide rotors that maintain structural integrity under heat stress while offering smooth braking surfaces to reduce noise and vibration. The 662632 rotor benefits from these design principles, making it suitable for vehicles requiring dependable disc brake components.

Technical Specifications and Features

This disc brake rotor features a vented design that allows air to flow between the rotor surfaces, helping to dissipate heat generated during braking. The rotor's nominal thickness is 1.496 inches (38.0 mm), with a discard thickness of 1.437 inches (36.5 mm), indicating when replacement is necessary to maintain safe braking performance. The overall height measures 4.874 inches (123.8 mm), and the outside diameter is 12.894 inches (327.5 mm), dimensions critical for proper fitment. The rotor includes eight mounting bolt holes arranged on a 5.709 inch (145.0 mm) bolt circle diameter, with a center hole diameter of 4.854 inches (123.3 mm). The smooth surface type ensures consistent contact with brake pads, reducing uneven wear.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Upgrading to vented rotors to improve heat dissipation and reduce brake fade
• Addressing rotor thickness below manufacturer discard limits
• Resolving uneven brake pad wear due to rotor surface irregularities
• Improving braking performance on vehicles compatible with 8-bolt, 12.894 inch diameter rotors

Installation Notes and Tips

Ensure the rotor matches the vehicle’s mounting bolt pattern and dimensions before installation. Clean the rotor surface to remove any protective coatings or debris. Use proper torque specifications on mounting bolts to avoid rotor warping. Since this rotor does not include an ABS tone ring, verify compatibility with the vehicle’s ABS system if applicable.
