If the clutch line for a manual transmission has an air bubble in it...how pressing on the clutch pedal helps?

The biggest problem everyone with a hydraulic clutch doesn't understand is,eventhough you have bled out all the air,the clutch is not or has not self adjusted yet. Think out it this way. Most brakes,if used wisely,will last 30-50,000 miles. You will or should replace your brake pads 3 times before you will or should put 1 clutch in. The master cylinder(for brakes) moves more fluid than one for a clutch,so,when a brake master cylinder has to "take-up" or adjust for wear,it will do so 3 times faster. Now,that clutch "take-up" or "self adjust" will take longer considering it does it at least 3 times slower.
