Power Stop 20-22 Mazda CX-30 Front Z23 Evolution Brake Kit

Front Brake Kit with Drilled and Slotted Rotors and Carbon Fiber Ceramic Pads for the Mazda CX-30

The Power Stop BK8755 is the Z23 Evolution front brake upgrade kit for 2020-2024 Mazda CX-30 models built for the US market. The BK8755 pairs cross-drilled and slotted zinc-plated rotors with Power Stop's Z23 carbon fiber ceramic brake pads, delivering improved stopping performance and reduced brake dust compared to the factory OEM setup. The BK8755 is a direct bolt-on replacement with no caliper or bracket modifications required. Cross-drilling and slotting in the rotor face improves heat dissipation during repeated braking events and provides an edge-to-edge bite on the pad surface for consistent pedal feel. The Z23 ceramic compound is designed as a low-dust, low-noise upgrade for daily drivers and light performance use, reducing the wheel face buildup associated with stock brake pads. The zinc dichromate coating on the rotor hats and vanes prevents corrosion during storage and in the field.

Frequently Asked Questions

The Power Stop BK8755 is the Z23 Evolution front brake kit for the 2020-2024 Mazda CX-30. The BK8755 includes cross-drilled and slotted zinc-coated rotors and Z23 carbon fiber ceramic pads for the front axle. It is a direct bolt-on kit with no modification required.

The Z23 Evolution upgrade introduces cross-drilling and slotting in the rotor face for improved heat dissipation and a fresh pad bite edge that reduces brake fade in repeated stops. The Z23 ceramic pad compound produces less dust and less squeal noise compared to most OEM pad formulations, keeping wheel faces cleaner over time.

The Power Stop BK8755 is designed for 2020-2024 Mazda CX-30 vehicles built for the US market. This includes the 2.5 S, 2.5 Turbo, 2.5 S Carbon Edition, and 2.5 Carbon Turbo trim levels. Verify your specific build market before ordering if you have a non-US CX-30.

No. The BK8755 includes new replacement rotors. The old rotors are replaced entirely as part of the kit, eliminating the need for machining or resurfacing.

Yes. The Power Stop Z23 Evolution kit uses DOT-compliant components designed for street use. The Z23 compound is not a race-only compound and is safe for normal street driving in all weather conditions.

Yes. Power Stop recommends a bed-in procedure for new pads and rotors. Perform 8-10 moderate stops from 30-35 mph to 10 mph without coming to a complete stop. Allow the brakes to cool between each stop. A proper bed-in transfers an even layer of pad material to the rotor for optimal initial performance.

The Z23 carbon fiber ceramic pads are a low-noise compound designed to reduce squeal compared to semi-metallic alternatives. Ensure the included hardware shims and lubricant are installed correctly during installation to minimize any potential noise after the break-in period.

California Proposition 65 requires a warning on products that contain certain chemicals known to the State of California to cause cancer or reproductive harm. Brake pads and rotors contain compounds that trigger this requirement. The warning applies to California residents. For questions about the specific compounds, contact Power Stop directly.

Installation Instructions

1. Safely lift and support the vehicle on jack stands at the recommended lift points. Remove the front wheels.
2. Remove the factory brake caliper mounting bolts. Do not let the caliper hang by the brake hose; support it with a wire hook or bungee cord.
3. Slide the factory rotor off the hub. If it is stuck, use a rubber mallet to break the corrosion bond at the hat section.
4. Clean the hub face thoroughly with a wire brush to remove rust scale and debris, then wipe with brake cleaner.
5. Mount the new BK8755 Power Stop rotor onto the hub and secure with a lug nut hand-tight to hold it in position while installing the caliper.
6. Install the new Z23 ceramic brake pads into the caliper bracket using the included hardware shims and caliper slide pin lubricant.
7. Compress the caliper piston fully using a C-clamp or brake piston tool before reinstalling the caliper over the new pads and rotor. Bleed the master cylinder reservoir if fluid overflows during compression.
8. Reinstall the caliper bolts and torque to the factory specification for the Mazda CX-30.
9. Reinstall the wheel and torque the lug nuts to factory specification.
10. Perform the Power Stop bed-in procedure before heavy braking use.
