Setup and Installation
Installation of brake components should ideally be performed by a qualified mechanic. Ensure your vehicle is safely supported on jack stands before beginning any work. Always refer to your vehicle's service manual for specific torque specifications and procedures.
Identifying Rotor Type (Solid vs. Vented):
It is crucial to verify whether your vehicle requires solid or vented rotors, especially for certain models like some Jeep and Chrysler vehicles, which may have either type within the same year. You can determine this by examining the side profile of your existing rotors. Solid rotors will appear as a single, thick disc, while vented rotors will have internal fins or channels between two disc faces for cooling.
Video: This video demonstrates how to identify the difference between solid and vented brake rotors by looking at their side profiles. This is important for selecting the correct replacement parts for your vehicle.
Ensure you order the same type of rotor that is currently installed on your vehicle.

Operating Your New Brakes
After installation, it is recommended to follow a proper break-in procedure for your new brake pads and rotors. This typically involves a series of moderate stops from varying speeds to properly seat the pads to the rotors and optimize performance.
Performance Benefits:
- Enhanced Stopping Power: The Z23 Carbon-Fiber ceramic pads and drilled & slotted rotors work together to provide superior braking.
- Reduced Brake Dust: The ceramic formula minimizes dust accumulation, helping to keep your wheels cleaner.
- Quiet Operation: Premium rubberized shims are designed to absorb vibrations and reduce noise during braking.
- Improved Heat Dissipation: Drilled and slotted rotors help to vent gases and dissipate heat, maintaining consistent performance.

Maintenance
Regular inspection of your brake system is essential for safety and longevity. Check brake pads for wear and rotors for signs of warping, cracking, or excessive scoring. The included ceramic brake lubricant should be applied to caliper slide pins and backing plates during installation to ensure smooth operation and prevent seizing.
Tips for Longevity:
- Avoid aggressive braking, especially during the initial break-in period.
- Periodically clean brake dust from wheels and calipers.
- Have your brake fluid checked and replaced according to your vehicle manufacturer's recommendations.

Troubleshooting
Common Issues and Solutions:
- Noise (Squealing/Grinding):
Ensure proper application of ceramic lubricant to contact points during installation. Verify that shims are correctly installed. If grinding, inspect pads for excessive wear or foreign objects. New pads may produce some noise during the initial break-in period.
- Incorrect Parts Received:
As noted in the "Setup and Installation" section, some vehicle models can use either solid or vented rotors. Always visually confirm the type of rotor currently on your vehicle before ordering to ensure compatibility and avoid receiving an incorrect kit. If you believe you have received the wrong parts, contact Power Stop customer support with your vehicle's year, make, model, and the type of rotors currently installed.
- Excessive Brake Dust:
While Z23 Carbon-Fiber ceramic pads are designed for low dust, some dust is normal. If dust is excessive, ensure proper break-in procedure was followed. Persistent excessive dust may indicate an issue with installation or component compatibility.
