IIRC, you have to pull a small clip out, and you might even have to disconnect the line and reconnect it. I havent looked at it in a while. If you do disconnect it, just be sure to bleed them. Have a friend pump the brakes, then hold the pedal down. Then open the bleeder on the caliper for a sec or two adn close it back. Then repeat about 5 times. Do both sides this way.
