• Outside diameter measures 11.220 inches (285 mm) for optimal braking surface
• Mounting bolt hole quantity: 5 with a bolt circle diameter of 4.5 inches (114.3 mm)
• Center hole diameter of 2.8 inches (71.1 mm) for secure hub alignment
• Nominal thickness of 0.475 inches (12.05 mm) and discard thickness of 0.433 inches (11.0 mm) to maintain safety standards

Detailed Product Description

This Raybestos Specialty - Truck disc brake rotor (part number 66565) features a vented design that improves heat dissipation during braking, reducing the risk of brake fade in demanding driving conditions. The drum-in-hat configuration integrates a parking brake drum within the rotor, providing a compact and efficient braking solution for compatible Ford and Mercury trucks. With precise dimensions including an outside diameter of 11.220 inches and a mounting bolt pattern of 5 bolts on a 4.5-inch circle, this rotor ensures a secure and exact fit. The nominal thickness of 0.475 inches and discard thickness of 0.433 inches help maintain braking performance and safety by indicating when rotor replacement is necessary.

Specialty - Truck Product Line Overview

The Raybestos Specialty - Truck line is designed specifically for truck applications requiring robust and reliable braking components. This product line focuses on delivering rotors that withstand the rigors of truck use, including heavier loads and frequent braking cycles. The 66565 rotor exemplifies this focus by combining vented rotor technology with a drum-in-hat design, tailored for Ford and Mercury truck models.

Common Applications and Issues Addressed

• Replacement for worn or warped rotors causing brake pulsation
• Upgrading from solid to vented rotors for improved heat management
• Resolving brake noise related to rotor surface irregularities
• Addressing reduced braking efficiency due to rotor thickness below discard limits
• Ensuring compatibility with parking brake systems integrated into the rotor

Installation Notes and Tips

• Verify rotor thickness before installation to ensure it meets nominal specifications
• Clean mounting surfaces to prevent rotor runout and vibration
• Torque mounting bolts to manufacturer specifications for secure fitment
• Inspect brake pads and hardware for wear during rotor replacement
• Ensure compatibility with vehicle’s parking brake system due to drum-in-hat design
