Setup and Installation
Important: Brake system installation requires specialized knowledge and tools. It is highly recommended that installation be performed by a qualified automotive technician. Improper installation can lead to brake failure and serious injury.
Pre-Installation Checks
- Verify that the kit components match your vehicle's make, model, and year (Mazda CX-30, 2020-2022).
- Inspect all components for any shipping damage or manufacturing defects. Do not install damaged parts.
- Ensure you have all necessary tools and safety equipment, including jack stands, wheel chocks, torque wrench, and personal protective equipment.
Installation Steps (General Guidelines)
- Prepare the Vehicle: Park the vehicle on a level surface, engage the parking brake, and chock the wheels. Loosen lug nuts, then raise the vehicle and secure it with jack stands. Remove the wheels.
- Remove Old Components: Carefully remove the brake caliper, old brake pads, and the original brake rotor. Follow your vehicle manufacturer's specific procedures for this step.
- Clean and Inspect: Clean the caliper bracket and hub assembly thoroughly. Inspect other brake system components (caliper, brake lines) for wear or damage.
- Install New Rotors: Place the new Power Stop drilled and slotted rotor onto the hub. Ensure it sits flush against the hub face.

- Install New Brake Pads and Hardware: Apply the provided high-performance lubricant to the caliper slide pins and the back of the brake pads where they contact the caliper. Install the new Z23 carbon-fiber ceramic brake pads and the upgraded hardware kit into the caliper bracket. Ensure the dual-layer rubberized shims are correctly positioned for noise insulation.

- Reassemble Caliper: Reinstall the caliper over the new pads and rotor. Torque all bolts to the vehicle manufacturer's specifications.
- Bleed Brake System: If brake lines were opened, or if recommended by your technician, bleed the brake system to remove any air.
- Reinstall Wheels: Mount the wheels and hand-tighten lug nuts. Lower the vehicle and torque lug nuts to manufacturer specifications.
- Repeat for all wheels.
Brake Break-In Procedure
Proper break-in (bedding-in) of new brake pads and rotors is crucial for optimal performance and longevity. Follow these steps:
- Perform 5-6 moderate stops from 40 mph down to 10 mph. Allow for a brief cooling period between stops.
- Perform 2-3 hard stops from 50 mph down to 10 mph.
- Drive for 5-10 minutes without using the brakes to allow them to cool completely.
- Avoid heavy braking or emergency stops for the first 200 miles after installation.
Operating Your Brake System
After proper installation and break-in, your Power Stop Z23 Evolution Sport Brake Kit is designed to provide enhanced stopping power with reduced dust and noise. Always drive responsibly and be aware of your vehicle's braking capabilities.
- Initial Feel: New brakes may feel slightly different initially. This is normal as the pads and rotors continue to seat.
- Environmental Factors: Wet conditions can temporarily reduce braking effectiveness. Apply brakes lightly to dry them out.
- Load and Speed: Braking performance can be affected by vehicle load and speed. Adjust your driving accordingly.

Maintenance
Regular inspection and maintenance are vital for the safety and performance of your brake system.
- Routine Inspection: Have your brake system inspected by a qualified technician at least once a year or every 12,000 miles, whichever comes first.
- Pad Wear: Monitor brake pad thickness. Replace pads when they reach their minimum recommended thickness (typically 2-3mm).
- Rotor Condition: Inspect rotors for excessive wear, deep grooves, cracks, or warping. While Power Stop rotors are designed for durability, they should be replaced if they show signs of significant wear or damage.
- Brake Fluid: Check brake fluid level and condition regularly. Replace brake fluid according to your vehicle manufacturer's recommendations.
- Cleaning: The Z23 pads are designed for low dust. However, occasional cleaning of wheels and brake components can help maintain appearance and prevent buildup.

Troubleshooting
This section addresses common issues that may arise with brake systems. If you experience any of these, consult a qualified technician.
| Symptom | Possible Cause | Action |
|---|---|---|
| Squealing/Grinding Noise | Improper break-in, worn pads, foreign object, caliper issues. | Re-evaluate break-in procedure, inspect pads for wear, check for debris, inspect caliper. |
| Vibration/Pulsation | Warped rotors, uneven pad wear, loose wheel bearings. | Inspect rotors for runout, check pad wear, inspect wheel bearings. |
| Reduced Braking Performance | Air in brake lines, contaminated pads, worn components, brake fluid issues. | Bleed brake system, inspect pads for contamination, check fluid level and condition. |
| Excessive Brake Dust | Normal during initial break-in, or if non-Z23 pads are used. | The Z23 pads are designed for low dust. If excessive dust persists after break-in, consult a technician. |
