The clutch disc's primary function is to transfer the engine power directly to the input transmission shaft. It is coupled with a flywheel and pressure plate to control the flow of power or torque. When the clutch pedal is depressed, the diaphragm springs compress the pressure plate on the clutch disc and the flywheel. As a result, the input shaft will spin at the same RPM as the engine. The springs relax when the clutch pedal is depressed, and the disc stops spinning, causing the input shaft to stop revolving.

1. Organic - For the Average Motorist
This type of clutch disc is one of the most basic types of the clutch disc. Phenolic resins, friction modifiers such as metallic powder or metal oxides, and compounded rubber are used to make organic facings. Clutch facings consist of frictional material used on the clutch disc for power transfer during the engagement period and reduce the amount of noise caused by clutches. The organic discs are ideal for conventional driving situations. They provide an excellent balance of effortless engagement, wear resistance, and strength.
2. Metal Disc
Metal clutch discs are usually made up of cast iron or high-carbon steel. This type of clutch disc that allows easier driving without fully engaging the clutch is known as half-clutching. The half-clutch driving technique keeps the vehicle from rolling back in bumper-to-bumper traffic or mountainous terrain. In the half-clutching technique, the driver engages forward or reverse gear (depending on the situation), keeps the brake pedal held, and slowly releases the clutch until the vehicle vibrates. This point is known as the biting point.
The disc's outer edge is light, resulting in a less inertial moment and improved clutch responsiveness at high engine speeds. Cast iron or high carbon steels are highly durable materials that enhance the clutch disc service life. These metals have good thermal properties and resist fading, so even if the clutch is frequently used in half-clutch conditions, the performance is not affected by high temperatures. When the clutch is only half depressed, it rubs against the flywheel, generating heat.
Replacement OE clutch discs offer the same advantages as factory-equipped clutch discs. But this means you will not be receiving any additional benefits found in aftermarket products. OE clutch discs also cost quite a bit more than their aftermarket counterparts. Aftermarket clutch discs are generally cheaper and provide many benefits over standard clutch discs. Aftermarket clutch discs match the OE parts' fit and performance and some even exceed that, making them a good bargain over their counterparts.
The most important factor to consider before investing your hard-earned money in any clutch discs is the compatibility with your vehicle’s make and model. Different friction materials of the clutch discs have different properties and are used in daily driving and racing applications. It is important to remember that an incorrect clutch disc will not fit in your vehicle’s transmission system, and even if it fits, it will deliver opposite results instead of enhancing performance.
When the clutch pedal is released and accelerated, the vehicle moves slowly while the engine races, usually in high gear. This is known as slipping and is common when a clutch disc is worn out. The clutch disc has reduced surface area to grip the flywheel and pressure plate because the friction material is practically worn away, making it difficult for the engine to transfer spinning power to the transmission.
If your gear system is working smoothly, it implies that your vehicle’s clutch and gearbox are working properly. The clutch releases the force between the engine and the transmission, allowing you to shift gears with ease. It will be incredibly difficult to transfer gears if the clutch fails to loosen the connection between the engine and the gearbox. If your vehicle’s clutch disc is damaged, it is due to worn-away friction material that reduces contact surface area. This will cause problems in transferring power from the engine to the transmission system. So if your car's gear shift has been problematic recently, it's time to replace your clutch disc.
While pressing the clutch, if you hear a grinding noise from the engine compartment, it indicates that the clutch disc is damaged or not functioning properly. The noise could be caused by a loose element inside the clutch disc. This issue needs to be taken seriously, and you must get your clutch disc inspected.
