Product Overview
The Power Stop Z23 Evolution Sport Brake Upgrade Kit is designed to enhance the braking performance of your vehicle. This kit provides a low-dust and noise-free upgrade compared to standard brake systems. It includes perfectly matched drilled and slotted rotors, Z23 Evolution Sport carbon-fiber ceramic brake pads, upgraded hardware, and high-performance lubricant.
The carbon-fiber ceramic brake pads are engineered for durability and provide increased stopping power without compromising daily drivability. The rotors are manufactured with G3000 metallurgy and OE tolerances, ensuring a direct fit without modifications. Precision drill holes facilitate maximum rotor cooling, while rounded slots help clear gas and debris for consistent braking. A Silver Zinc Dichromate plating protects the rotors against rust and corrosion.

Setup and Installation
Installation of the Power Stop K7612 Z23 Brake Kit should be performed by a qualified mechanic or an individual with experience in automotive brake systems. Improper installation can lead to brake failure and serious injury.
Safety Precautions:
- Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
- Ensure the vehicle is securely supported on jack stands on a level surface.
- Refer to your vehicle's service manual for specific torque specifications and procedures.
- Do not reuse old hardware unless explicitly stated in the vehicle's service manual.
General Installation Steps (Consult Vehicle Manual for Details):
- Safely lift and support the vehicle. Remove the wheels.
- Remove the brake caliper and old brake pads.
- Remove the old brake rotor.
- Clean the hub surface thoroughly to ensure proper seating of the new rotor.
- Install the new Power Stop drilled and slotted rotor. Ensure it sits flush against the hub.
- Install the new Z23 carbon-fiber ceramic brake pads and upgraded hardware. Apply high-performance brake lubricant to contact points as recommended.
- Reinstall the brake caliper and torque all fasteners to the manufacturer's specifications.
- Repeat for all wheels.
- Bleed the brake system if necessary, following your vehicle's service manual.
- Reinstall the wheels and lower the vehicle.

Operating Instructions (Break-in Procedure)
Proper break-in (bedding-in) of new brake pads and rotors is crucial for optimal performance and longevity. Follow these steps carefully:
- Perform 5-6 moderate stops from 40 mph down to 10 mph. Avoid coming to a complete stop.
- Allow the brakes to cool for 10-15 minutes.
- Perform 2-3 hard stops from 50 mph down to 10 mph. Again, avoid coming to a complete stop.
- Allow the brakes to cool completely for at least 30 minutes before normal driving.
During the break-in period, avoid heavy braking, sudden stops, and prolonged braking (e.g., riding the brakes down a long hill). This process transfers a thin layer of pad material to the rotor surface, which is essential for optimal friction and reduced noise.
Maintenance
Regular inspection and maintenance of your brake system are vital for safety and performance.
Recommended Maintenance Schedule:
- Every 5,000-7,500 miles or 6 months: Inspect brake pads for wear, rotors for scoring or warping, and brake fluid level.
- Annually: Have the brake system professionally inspected, including calipers, lines, and hoses. Consider flushing and replacing brake fluid as per your vehicle manufacturer's recommendations.
The Z23 Carbon Fiber Ceramic pads are designed for low dust and noise-free operation. However, any significant changes in brake feel, noise, or performance should be addressed immediately by a qualified technician.
Troubleshooting
| Symptom | Possible Cause | Solution |
|---|---|---|
| Squealing/Grinding Noise | Improper break-in, worn pads, foreign object, caliper issue. | Re-perform break-in, inspect pads for wear, check for debris, inspect calipers. |
| Vibration/Pulsation during braking | Warped rotors, uneven pad wear, loose wheel bearings. | Inspect rotors for runout, check pad wear, inspect wheel bearings. |
| Soft/Spongy Brake Pedal | Air in brake lines, low brake fluid, faulty master cylinder. | Bleed brake system, check fluid level, inspect master cylinder. |
| Excessive Brake Dust | Normal during initial use, or incorrect pad material. | Ensure proper break-in. Z23 pads are designed for low dust; if excessive, re-evaluate installation or components. |
If you experience any persistent brake issues, consult a professional automotive technician immediately.
