Clutch Master Cylinder
The component of the clutch that converts the pressure of the driver’s foot pressing the pedal into hydraulic pressure is called the master cylinder. More specifically, when the clutch pedal is pushed it moves the master cylinder inward, creating hydraulic pressure. This pressure then travels to the slave cylinder and eventually to the pressure plate where the clutch is disengaged. The most common issue with clutch master cylinders is leaks. The master cylinder is comprised of an aluminum housing, a piston, and several seals—if there is a leak in any of those seals, fluid will drain out and air will come into the aluminum housing. Introducing air into the system will make it more difficult to generate enough hydraulic pressure.
Pressure Plate
A clutch is made up of three main components—the pressure plate, flywheel, and clutch disc. These elements work together to transfer power from the engine to the transmission while also allowing the engine to continue running when the wheels are stopped. The first component is the flywheel—a large metal disc that is bolted to the crankshaft of the engine. Attached to the flywheel is the pressure plate, which is essentially a spring-loaded clamp with a sheet metal cover. The clutch disc is a steel plate covered with a frictional material that fits between the flywheel and the pressure plate. When the clutch is engaged, the pressure plate squeezes the disc against the flywheel, effectively transferring power from the engine to the transmission. If the pressure plate is malfunctioning, it will not be able to apply enough pressure to hold the clutch disc against the flywheel and power will not be transferred. Some symptoms of a failing pressure plate include clutch slippage, inability to engage transmission into gear, a shudder when the clutch is engaged, and noise or vibration in the clutch. If you’re experiencing any of these issues have your vehicle looked at by a professional as soon as possible. Harry’s Auto Repair has expert technicians and a state of the art service center in Pleasanton, CA.
Clutch Disc
A vehicle’s clutch is responsible for transferring power from the engine to the transmission and drive wheels. Engaging the clutch initiates this transfer while disengaging it prevents power from going to the transmission. Three main components make this possible—the pressure plate, flywheel, and clutch disc. The flywheel is a large metal disc that is bolted to the crankshaft of the engine. Attached to the flywheel is the pressure plate, which is a spring-loaded clamp with a sheet metal cover. Fit between the two is a steel plate covered with frictional material called a clutch disc, the center of which is designed to fit into the input shaft of the transmission. When the clutch is engaged, the pressure plate squeezes the disc against the flywheel. The flywheel takes power from the engine and transfers it to the transmission with the clutch disc as its intermediary. Without the clutch disc, this transfer would not be possible and the transmission would not be able to get power to the drive wheels. Some symptoms of a bad clutch disc include the inability to engage the transmission, clutch slippage, a shudder when the clutch is engaged, and noise or vibration around the clutch.
Fly Wheel
The clutch is responsible for transferring power from the engine to the transmission and the drive wheels. Engaging the clutch initiates this transfer while disengaging it prevents power from going to the transmission. The component of the engine that connects to the clutch is called the flywheel. The flywheel is a metal disc that is attached to the engine’s crankshaft and provides a friction surface on which the clutch can link to. In addition, the flywheel acts as a balancer for the engine, limits its vibrations, and transfers power from the starter to the engine. Because the flywheel is exposed to pressure and extreme heat, it is prone to becoming worn, warped, or cracked. Symptoms of a bad flywheel include vibration through the clutch, a burning smell, and clutch slippage. At Harry’s Auto Repair, we recommend having your vehicle’s clutch and flywheel checked periodically for wear to prevent more expensive damage down the road.

Clutch Slave Cylinder
The clutch’s slave cylinder is part of a hydraulic system that converts the force of your foot hitting the pedal into hydraulic pressure. Consequently, when there is a leak in the cylinder, fluid is released and air is let in. This will cause your clutch pedal to feel soft or loose when pressed. There are several other major signs that your clutch is leaking including: low fluid levels, trouble shifting gears, and dark liquid on the ground below the slave cylinder. If you’re experiencing any of these issues, bring your vehicle to our service and repair center, located in Pleasanton, CA. One of Harry’s Auto Repair expert technicians are ready to get you shifting smoothly again!
