Setup and Installation
The Power Stop K1378 kit is designed for direct bolt-on installation, requiring no modifications to your vehicle. However, professional installation is recommended. Ensure you have the correct kit for your vehicle by verifying the fitment for 2005-2007 Ford Focus models with rear disc brakes.
Before Installation:
- Confirm the kit fits your specific vehicle model and year (e.g., 2005-2007 Ford Focus Rear Disc).
- Identify if your vehicle requires solid or vented rotors for the rear wheels. Some models, even within the same year, may have either type. Visually inspect your current rotors to determine the correct type.
- Gather all necessary tools for brake system replacement.
- Ensure the vehicle is securely lifted and supported on jack stands.
Installation Steps (General Guidelines):
- Remove the wheels and old brake components (calipers, pads, rotors).
- Clean the hub assembly thoroughly to ensure proper seating of the new rotor.
- Install the new Power Stop drilled and slotted rotors.
- Apply the provided high-performance lubricant to caliper slide pins and other contact points as specified in a service manual.
- Install the Z23 Evolution Sport carbon-fiber ceramic brake pads with the new hardware.
- Reinstall the brake calipers and ensure all bolts are torqued to manufacturer specifications.
- Bleed the brake system if necessary, following vehicle manufacturer guidelines.
- Reinstall the wheels and lower the vehicle.

Operating and Break-in Procedure
After installing new brake components, a proper break-in procedure is crucial to ensure optimal performance and longevity of your Power Stop Z23 Evolution Sport Brake Kit. This process, often called "bedding-in," transfers a thin layer of brake pad material onto the rotor surface, which is essential for consistent braking and noise reduction.
Recommended Break-in Procedure:
- Find a safe area with minimal traffic.
- Accelerate the vehicle to 35 mph (56 km/h).
- Apply moderate braking pressure to slow down to 5 mph (8 km/h). Do not come to a complete stop.
- Release the brakes and accelerate back to 35 mph (56 km/h).
- Repeat this process 5-6 times.
- After the last stop, drive for several minutes without applying the brakes to allow the system to cool down. Avoid hard braking during this cooling period.
This procedure helps to properly seat the pads and rotors, ensuring maximum stopping power and minimizing noise and vibration.

Maintenance
Regular inspection and maintenance of your brake system are vital for safety and performance. The Power Stop Z23 Evolution Sport Brake Kit is designed for durability, but periodic checks will ensure its long-lasting effectiveness.
General Maintenance Tips:
- Visual Inspection: Periodically inspect brake pads for wear and rotors for any signs of damage, deep grooves, or excessive rust.
- Brake Fluid: Check brake fluid levels and condition according to your vehicle manufacturer's recommendations.
- Cleaning: The low-dust ceramic formula helps keep wheels cleaner, but regular cleaning of wheels and brake components can prevent buildup.
- Professional Check-ups: Have your brake system professionally inspected during routine vehicle maintenance.

Troubleshooting
While the Power Stop Z23 Evolution Sport Brake Kit is designed for reliable performance, occasional issues may arise. Here are some common troubleshooting tips:
| Symptom | Possible Cause | Solution |
|---|---|---|
| Brake Noise (Squealing/Grinding) | Improper break-in, worn pads, foreign material, or improper installation. | Ensure proper break-in. Inspect pads for wear. Check for debris between pad and rotor. Verify correct installation and lubrication of hardware. |
| Vibration or Pulsation | Rotor run-out, uneven pad transfer, or warped rotors (less common with quality rotors). | Re-perform break-in procedure. Inspect rotors for damage or excessive run-out. Ensure proper torque on wheel lug nuts. |
| Reduced Braking Performance | Improper break-in, air in brake lines, or contaminated pads. | Perform break-in procedure. Check brake fluid level and bleed system if air is present. Inspect pads for contamination (oil, grease). |
If issues persist, consult a certified automotive technician.
