Clutch hydraulics are responsible for engaging and disengaging the engine from the transmission. Clutch hydraulics are made up of a master- and slave cylinder, clutch plate, flywheel, pressure plate and clutch release bearing all of which contribute to the safety of you as a driver. When the driver presses the clutch pedal, the fluid in the hydraulic clutch system flows to the clutch slave cylinder.
To work properly, the clutch needs proper clearance between the foot pedal and the clutch operating lever. Without proper clearance, you get clutch slip because the pressure plate is unable to exert full pressure on the friction plate. When clutch hydraulics components malfunction, drivers may only be able to start the car in neutral, the car may stall at a stop sign and the clutch pedal feels as though it goes to the floor with no rebound.
