What happens if you have air in your clutch?

If you dont bleed it you probably have air in the lines which means your clutch is probably going to start sticking to the floor. Then, what causes air in clutch line? A more-common cause of intermittent clutch action is air invading the hydraulic clutch release mechanism through a worn seal in the clutch master or slave cylinder.

Overview of Mitsubishi Services

An air cleaner is vital to engine performance. As outside air travels through the intake on its way to the engine, it passes through the air cleaner element. Dirt and debris, harmful to an engine, are trapped in the air cleaner element. Over time, as more material is trapped, the air flow rate decreases, restricting the air that the engine needs.

What is Bernoulli's Equation - Bernoulli's Principle ...

According to Bernoulli's principle, faster moving air exerts less pressure, and therefore the air must exert an upward force on the ball. In fact, in this case the use of Bernoulli's principle may not be correct. The Bernoulli's principle assumes incompressibility of the air, but in reality the air is easily compressible.

what is the effect of air in Clutch line? | Cleaning, Oil ...

If there's air in the line it should feel "spongy" or like the clutch isn't disengaging when you pull in the clutch lever while in gear. The reason for this is that air can be compressed (air compressor) but fluid cannot be. As far as locking up the rear end, if you down shift aggressively, you can get what feels like a lock up.
