The engine is one complicated puzzle, with every component relying on something else to be operational. One component out and your engine won't have the power to drive your car around. That said, it is best that you learn more of your clutch disc, which plays an important role in the smooth transference of force to the driven member from the engine. Since you aren't going anywhere with it gone, it is best that you know some important points on what causes it to break down.
When you leave the clutch pedal alone, the clutch disc is engaged to the engine flywheel and connects the transmission system to the engine, making them rotate at the same time. Brands like the ACT clutch disc are made from a compound of organic resin and copper wires that offer some optimum friction capabilities. When you feel the need to change gears to alter your car's speed output, you can't just pull your transmission lever to do that, you have to disengage the clutch disc first to disconnect the transmission from the engine.
A worn-out car clutch disc sticks and causes all the grinding noise you hear after disengaging the clutch disc. The grinding is caused by the clutch disc's failure to instantly let go of the flywheel's speed when you press on the clutch, which causes it to still run at a slower speed than the flywheel until both plates have separated. That, along with the failure of the clutch disc to engage immediately when you release the clutch, causes the wearing out of the clutch friction material. This friction material is similar to those in the brake pads of your brake calipers and will last for up to 80,000 miles.
Sticking is often caused by the lack of pressure needed to release the clutch and will lead to a clutch disc replacement sooner. This can be because of several other reasons. One, the clutch cable that connects the pedal to the release fork may be loose. Also, your master and slave clutch cylinders may not be providing the right hydraulic pressure to release the clutch. Leaks in the hydraulic line can also cause sticking, as well as vacuums in the clutch fluid. Lastly, make sure that your clutch pedal is aligned well in order to give every amount of pressure needed to release the clutch.
Giving your entire clutch assembly a regular check up can prevent clutch disc slippage and sticking and the eventual wearing out of the clutch disc's friction materials. Your driving habits are also very much accountable for the damage on your clutch.
