Product Line Details: Power Stop Rear Drilled, Slotted and Zinc Plated Rotors

This Power Stop - Rear Drilled, Slotted and Zinc Plated Brake Rotor Pair belongs to a product line focused on improving brake rotor durability and performance. The drilled and slotted surface design helps reduce brake fade by allowing heat and gases to escape more efficiently during braking. Zinc plating provides a protective coating that resists rust and corrosion, which is especially beneficial for rear rotors exposed to road elements. This combination supports consistent braking performance and rotor longevity on Ford Mustang vehicles.

Technical Specifications and Features

The AR8142XPR rotor set features solid rotors with a 267 mm outside diameter and a mounting bolt hole circle diameter of 114.30 mm, accommodating 5 lug holes. The nominal thickness ranges between 12.80 mm and 14.00 mm, with discard thickness values at 12.80 mm and 0.50 mm, indicating when replacement is necessary. The rotors have an overall height of 2.00 inches (51.00 mm), ensuring proper fitment and clearance within the rear brake assembly. The slotted and drilled surface type enhances braking efficiency by improving pad bite and heat dissipation.

Common Applications and Problem Solving

• Replacement for worn or warped rear brake rotors on Ford Mustang models
• Addresses brake fade caused by excessive heat buildup during aggressive driving
• Helps reduce rust and corrosion on rear rotors exposed to moisture and road salt
• Improves braking response and pad cleaning with slotted and drilled design
• Restores proper rotor thickness and surface condition for safe braking

Installation Notes and Tips

When installing the Power Stop AR8142XPR rotor pair, ensure the mounting surface is clean and free of debris. Verify the rotor thickness before installation to confirm it meets minimum specifications. Use proper torque settings on lug nuts to avoid rotor warping. It is recommended to replace brake pads simultaneously to optimize braking performance. Follow manufacturer guidelines for break-in procedures to ensure rotor and pad longevity.

Quality Assurance and Warranty

Power Stop brake rotors are manufactured to meet or exceed OEM standards for fit, form, and function. The zinc plating provides additional corrosion resistance to extend rotor life. While specific warranty details are not provided here, Power Stop products typically come with a limited warranty against defects in materials and workmanship.
