depends which spring came off.. Usually it's the brake light spring that comes off (mine was missing when i first bought my quad.) If you want your brake light to work when you press down on the brake pedal then you'll need to replace the spring. If you never use just the back brake alone, then I wouldn't worry about it because the front brake will activate the brake light (that's what that clicking noise is when you pull in the front brake)
If the other spring fell off, then your brake will have no tension on it and will put pressure on the master cylinder which isn't good.. Also, you probably won't be able to use it.
