Introduction
The Power Stop Z23 Evolution Sport Brake Upgrade Kit is designed to enhance the braking performance of your daily-driven vehicle. This kit provides a low-dust, noise-free upgrade to your existing brake system, offering increased stopping power without compromising everyday drivability. It includes all necessary components for a complete rear brake service.
Safety Information
Always prioritize safety when working on your vehicle's braking system. Improper installation or maintenance can lead to serious injury or vehicle damage. If you are not confident in your mechanical abilities, seek professional assistance.
- Wear appropriate personal protective equipment, including safety glasses and gloves.
- Ensure the vehicle is securely supported on jack stands on a level surface before beginning work.
- Never rely solely on a jack to support the vehicle.
- Allow brake components to cool completely before handling.
- Keep brake fluid away from painted surfaces, as it can damage paint.
- Dispose of old brake components and fluids responsibly according to local regulations.

Setup and Installation
Installation of the Power Stop Z23 Evolution Sport Brake Kit requires mechanical knowledge and specific tools. If you are unsure about any step, consult a certified mechanic.
General Installation Steps:
- Prepare the Vehicle: Park the vehicle on a level surface, engage the parking brake, and block the wheels. Loosen the lug nuts on the rear wheels.
- Lift and Secure: Safely lift the rear of the vehicle using a jack and support it with jack stands. Remove the rear wheels.
- Remove Old Components: Remove the brake caliper bolts, then carefully remove the caliper and support it to avoid stressing the brake hose. Remove the old brake pads and the caliper bracket. Remove the old brake rotor.
- Clean and Inspect: Thoroughly clean the hub assembly and caliper bracket. Inspect all brake components for wear or damage, including the brake hose and caliper piston.
- Install New Rotor: Place the new Power Stop drilled and slotted rotor onto the hub. Ensure it sits flush.
- Install Caliper Bracket and Pads: Install the caliper bracket. Apply the provided high-performance brake lubricant to the caliper slide pins and any metal-to-metal contact points on the new brake pads and hardware. Install the new Z23 Carbon-Fiber Ceramic brake pads with the new hardware.
- Reinstall Caliper: Carefully compress the caliper piston (if necessary) and reinstall the caliper over the new pads and rotor. Secure the caliper bolts to the manufacturer's specified torque.
- Bleed Brakes (if necessary): If the brake system was opened or air entered the lines, bleed the brakes according to your vehicle's service manual.
- Reinstall Wheels: Reinstall the wheels, hand-tighten the lug nuts, lower the vehicle, and then torque the lug nuts to the manufacturer's specifications.
Note: This kit is designed for a direct bolt-on installation without modifications, adhering to strict OE equipment tolerances.
Operating Instructions: Brake Break-In Procedure
Proper break-in (bedding-in) of new brake pads and rotors is crucial for optimal performance, longevity, and to prevent noise. Follow these steps carefully:
- Initial Stops: Perform 5-6 moderate stops from 40 mph (64 km/h) down to 10 mph (16 km/h). Allow a short cooling period between each stop. Do not come to a complete stop.
- Harder Stops: Perform 2-3 harder stops from 50 mph (80 km/h) down to 10 mph (16 km/h). Again, allow a short cooling period between each stop and avoid coming to a complete stop.
- Final Cooling: Drive for several miles without heavy braking to allow the brakes to cool down gradually.
During the break-in process, you may notice some smoke or a distinct smell. This is normal. Avoid aggressive braking or prolonged stops immediately after installation until the break-in procedure is complete.

Maintenance
Regular inspection and maintenance of your braking system are essential for safety and performance.
- Routine Inspection: Inspect brake pads and rotors every 10,000-12,000 miles (16,000-19,000 km) or as recommended by your vehicle manufacturer. Check for pad wear, rotor condition (cracks, excessive scoring, warping), and proper caliper function.
- Brake Fluid: Check brake fluid level and condition regularly. Replace brake fluid according to your vehicle manufacturer's recommendations.
- Cleaning: Keep brake components clean from excessive dirt and debris. The silver zinc dichromate coating on the rotors helps prevent rust and corrosion, but regular cleaning can further extend their lifespan.
- Hardware: Ensure all brake hardware is free of corrosion and moves freely. Replace any worn or corroded hardware.
Troubleshooting
If you experience issues with your Power Stop Z23 brake kit, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Brake Noise (Squealing/Grinding) | Improper break-in, lack of lubricant on contact points, worn pads, debris. | Ensure proper break-in. Reapply brake lubricant. Inspect pads for wear or foreign objects. |
| Reduced Braking Performance | Improper break-in, air in brake lines, worn pads, contaminated pads/rotors. | Perform break-in procedure. Bleed brake system. Inspect for fluid leaks or contamination. |
| Vibration/Pulsation during Braking | Rotor run-out, uneven pad transfer, warped rotors (less common with quality rotors). | Re-check rotor installation. Ensure proper break-in. Inspect rotors for damage. |
| Excessive Brake Dust | Normal during initial use, or if not Z23 pads. | The Z23 pads are designed for low dust. If excessive, ensure correct pads are installed and perform break-in. |
If troubleshooting steps do not resolve the issue, consult a professional mechanic.
