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 holes and slots help reduce brake fade by improving heat dissipation and allowing gases and debris to escape during braking. The zinc plating adds a layer of rust resistance, extending rotor life especially in environments prone to moisture and corrosion. This rotor pair is vented to further enhance cooling, making it suitable for vehicles like the Lexus 4Runner and Toyota FJ Cruiser that may experience demanding driving conditions.

Detailed Product Description

The JBR971XPR disc brake rotor set is designed to meet the specific braking needs of rear axles on Lexus and Toyota SUVs. The vented rotor construction allows air to flow between the rotor surfaces, reducing heat buildup during braking. The slotted and drilled surface pattern improves pad contact and helps clear away brake dust and water, contributing to consistent braking performance. With a nominal thickness of 16.00 mm and a discard thickness of 0.63 mm, these rotors provide a clear service life indicator to maintain safety standards. The zinc plating protects the rotor from rust, which is critical for maintaining rotor integrity over time.

Common Applications and Problem Solving

• Replacement for worn or warped rear brake rotors on Lexus 4Runner, GX470, Toyota FJ Cruiser, and Sequoia
• Addresses brake fade caused by excessive heat during towing or off-road use
• Reduces rust and corrosion buildup on rear rotors in humid or wet climates
• Improves braking response and pad bite with slotted and drilled rotor surfaces
• Helps eliminate brake noise and vibration associated with uneven rotor wear

Installation Notes and Tips

• Ensure compatibility with rear brake system of Lexus 4Runner, GX470, Toyota FJ Cruiser, or Sequoia before installation
• Check rotor thickness and discard limits regularly to maintain safe braking performance
• Use proper torque specifications on mounting bolts to avoid rotor warping
• Inspect brake pads and replace if worn to optimize rotor performance
• Clean rotor surface before installation to remove any protective coatings or debris

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 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.
