Installation Notes and Tips
Verify the vehicle is a 2002-2004 Kia Spectra with front disc brakes before ordering. Bench bleed the master cylinder before installation, then bleed the brake system thoroughly after mounting. Mounting hardware, brake booster, push rod, sensor, and brake pressure switch are not included, so reuse or source those components as needed. Use only DOT 3 or DOT 4 brake fluid and confirm all line connections are clean and properly tightened.
