Product Line Details

The Power Stop - Front Drilled, Slotted and Zinc Plated Brake Rotor Pair line focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce brake fade. The zinc plating provides a protective coating that helps prevent rust and corrosion, extending the rotor's service life. This product line is designed to offer a balance of performance and durability for front brake applications on compatible vehicles.

Technical Specifications and Features

This disc brake rotor set features a vented design that promotes airflow to dissipate heat generated during braking, reducing the risk of warping. The slotted and drilled surface enhances pad cleaning and gas evacuation, which helps maintain consistent braking performance. The nominal thickness of 30.50 mm ensures structural integrity, while the discard thickness of 1.20 mm indicates when the rotor should be replaced. The rotors have an outside diameter of 350 mm and an overall height of 54.90 mm, matching OEM specifications for proper fitment.

Compatible Vehicles and Applications

• Designed specifically for Dodge Durango front brake systems
• Compatible with Jeep Grand Cherokee, Grand Cherokee L, and Grand Cherokee WK front brakes
• Ideal for drivers seeking replacement rotors that maintain factory fit and function
• Suitable for vehicles requiring 5 lug holes with a 127 mm bolt circle diameter

Common Issues Addressed by This Rotor Set

• Brake fade caused by excessive heat buildup during braking
• Corrosion and rust on rotor surfaces reducing lifespan
• Uneven brake pad wear due to poor rotor surface condition
• Vibration or pulsation from warped rotors
• Reduced braking efficiency from clogged or glazed rotors

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness is above the discard thickness of 1.20 mm to maintain safety standards. Use proper torque specifications for lug nuts to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to optimize braking performance.
