Technical Description and Specifications

This vented disc brake rotor features a smooth surface type optimized for consistent pad contact and braking efficiency. The rotor’s nominal thickness of 1.441 inches ensures durability and longevity, while the discard thickness of 1.320 inches indicates the minimum safe thickness before replacement is necessary. The rotor’s 15-inch outside diameter and 10 mounting bolt holes with a 7.252-inch bolt circle diameter provide compatibility with specific vehicle hubs. The integrated ABS tone ring supports vehicles equipped with anti-lock braking systems, enhancing safety and control. The hat-shaped design with straight vanes promotes effective heat dissipation, reducing the risk of brake fade during extended use.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation or noise
• Upgrading to rotors with ABS tone rings for vehicles with ABS systems
• Addressing rotor thickness below manufacturer discard limits to maintain braking safety
• Resolving overheating issues with vented rotor design for improved heat management
• Ensuring proper fitment on vehicles requiring 10-bolt mounting with specific bolt circle diameter

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the nominal thickness of 1.441 inches. The rotor mounts behind the hub and requires alignment with the 10 mounting bolt holes on a 7.252-inch bolt circle diameter. Proper cleaning of the rotor surface before installation is recommended to remove any protective coatings or debris. Verify ABS tone ring functionality if applicable to the vehicle’s braking system. Bearings are not included and should be inspected separately during installation.
