Hey everybody, I did a grande front disc brake conversion and when pressing down ever so slightly on the brakes it's so sensitive I can't help but to jerk forward. After researching the forums I ordered a prop valve. Is it a easy process adding it to the brake system? I want to tackle the install myself but definitely don't want to make a mistake with such a critical part of the car being that I must be able to stop lol. Out of curiosity I called and asked the local classic mustang mechanic and he said he would charge me $250 for the install. Is this right?
