This line is designed to meet or exceed factory specifications for rear disc brake rotors, making it suitable for standard replacement needs.

Detailed Product Description

The AR85221EVC rotor is a full cast, vented disc brake rotor designed for rear axle applications. Its vented construction improves heat dissipation during braking, reducing the risk of brake fade. The rotor’s nominal thickness of 36.40 mm and discard thickness of 34.00 mm provide a solid balance between durability and performance. The smooth surface finish ensures consistent pad contact and braking efficiency. With a 10-lug hole configuration and a mounting bolt hole circle diameter of 163.30 mm, this rotor is engineered for precise fitment on compatible vehicles. The rust-resistant Geomet coating protects the rotor from corrosion, which is especially beneficial in regions with harsh weather or road salt exposure.

Compatible Vehicles and Common Applications

This rotor is compatible with various makes and models requiring a 15-inch rear vented disc brake rotor with a 10-lug pattern and the specified dimensions. It is commonly used in vehicles that demand reliable rear braking performance and corrosion resistance.

• Replacement for worn or warped rear rotors
• Addressing brake noise or vibration issues
• Improving rotor lifespan in corrosive environments
• Restoring braking performance after rotor damage
• Standard replacement for routine brake maintenance

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 34.00 mm before installation. Clean the rotor surface to remove any protective coating residue before mounting. Verify the 10-lug hole pattern and mounting bolt hole circle diameter of 163.30 mm for proper fitment. This rotor does not include an ABS tone ring, so confirm compatibility with your vehicle’s ABS system. Proper torque specifications should be followed when securing the rotor to avoid warping.

Quality Assurance and Warranty

Power Stop rotors are manufactured to meet OEM standards for quality and durability. The Geomet coating provides additional protection against rust and corrosion, contributing to longer rotor life. While specific warranty details are not provided, Power Stop products typically come with a limited warranty against manufacturing defects. Always consult the manufacturer or authorized distributor for warranty terms related to part number AR85221EVC.
