Product Line Details: Power Stop - Rear Drilled, Slotted and Zinc Plated Brake Rotor Pair

This Power Stop product line focuses on rear brake rotors that combine drilled and slotted surfaces with a zinc plating finish. The drilled and slotted design enhances braking efficiency by allowing gases, heat, and debris to escape more effectively, while the zinc plating provides a protective layer against rust. This combination is particularly beneficial for heavy-duty Ford trucks that require consistent braking performance under demanding conditions.

Technical Description and Specifications

The AR8571XPR rotor set features a vented rotor type, which improves airflow to reduce heat buildup during braking. The nominal thickness measures 30.00 mm, with a discard thickness of 28.00 mm, ensuring the rotors maintain structural integrity throughout their service life. The overall diameter of 326.00 mm (12.80 inches) and height of 98.50 mm (3.90 inches) are designed to match the rear brake assemblies of compatible Ford models. The drilled and slotted surface type enhances braking response and helps maintain clean contact between the brake pad and rotor. Additionally, the zinc plating offers rust resistance, extending the rotor's durability in various weather conditions.

Common Applications and Problem Solving

• Replacement for worn or warped rear brake rotors on Ford Excursion, F-250 Super Duty, and F-350 Super Duty
• Improves braking performance in wet or muddy conditions by evacuating water and debris
• Reduces brake fade during heavy towing or hauling by enhancing heat dissipation
• Prevents rust and corrosion that can lead to rotor surface degradation
• Addresses vibration or noise issues caused by uneven rotor surfaces

Installation Notes and Tips

When installing the AR8571XPR brake rotor set, ensure the mounting surfaces are clean and free of debris. Verify the rotor thickness before installation to confirm it meets the minimum discard thickness of 28.00 mm. Use proper torque specifications for the 8 lug holes with a 170.00 mm bolt circle diameter. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. After installation, perform a bed-in procedure to ensure proper rotor and pad contact.

Quality Assurance and Warranty

Power Stop brake rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The zinc plating provides additional protection against corrosion, contributing to the rotor's longevity. While specific warranty details are not provided here, Power Stop products typically come with a limited warranty covering defects in materials and workmanship. Consult the product packaging or manufacturer for exact warranty terms.
