Detailed Product Description

This Power Stop rear rotor is specifically designed for the Subaru Ascent, ensuring precise fitment and optimal braking performance. The vented rotor type enhances heat dissipation during braking, reducing the risk of brake fade under demanding conditions. The Geomet coating provides a protective layer that resists rust and corrosion, extending the rotor's service life and maintaining consistent braking efficiency. With a nominal thickness of 0.67 inches (17.00 mm) and a discard thickness of 0.59 inches (15.00 mm), this rotor meets strict specifications for safe replacement and performance.

The rotor's overall height measures 1.90 inches (47.10 mm), and it features an outside diameter of 13.00 inches (331.00 mm). The mounting bolt hole circle diameter is 4.50 inches (114.30 mm), accommodating 5 lug holes, which aligns with the Subaru Ascent's rear brake assembly requirements.

Power Stop - Rear Genuine Geomet Coated Rotor Product Line

The Power Stop - Rear Genuine Geomet Coated Rotor product line focuses on delivering rotors with advanced corrosion resistance and reliable vented designs. This line is tailored for rear brake applications where durability and consistent braking performance are critical. The Geomet coating technology used in this product line helps protect the rotor surface from rust, which is especially beneficial in regions with harsh weather conditions or frequent road salt exposure.

Common Applications and Issues Addressed

• Replacement for worn or warped rear rotors on Subaru Ascent
• Improves braking consistency by reducing heat buildup
• Prevents rust and corrosion that can lead to premature rotor failure
• Restores proper rotor thickness for safe braking performance
• Addresses brake noise and vibration caused by damaged rotors

Installation Notes and Tips

Ensure the rotor surface and hub are clean and free of debris before installation. Verify the rotor thickness is within the discard limits specified (minimum 0.59 inches or 15.00 mm). Use proper torque specifications for the mounting bolts to avoid rotor warping. It is recommended to inspect brake pads and replace them if worn to maintain optimal braking performance with the new rotor.

Quality Assurance

Power Stop rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The Geomet coating provides enhanced corrosion resistance, contributing to longer rotor life. While no specific warranty information is provided, Power Stop products are known for consistent quality and reliability in automotive braking components.
