Installation Notes and Tips

Before installation, verify the vehicle is a 1990 Nissan 300ZX with front disc brakes and confirm the bore size and mounting pattern match the original unit. Transfer or source any required external components separately, since the reservoir, cap, push rod, booster, sensor, and pressure switch are not included. After installation, bleed the brake system thoroughly and inspect all hydraulic connections for leaks.
