Increasingly present in new cars, the hydraulic clutch has come to replace the system with cables. The main advantage for the driver is a softer pedal and longer durability, without that headache staying on the street with the cable bursting.
Before anything else about the hydraulic system is worth a quick explanation about the function of the left pedal of the car. Cars with manual transmission have as main part of the transmitter assembly, the clutch. The function of the clutch pedal is to cut off the communication between the engine and the wheels because you can not move with the car in motion. There are two types of clutch drive: hydraulic and cable.
The hydraulic clutch uses oil to drive the system through cylinders and actuators. Already the clutch cable the drive is made by a cable connected to the pedal and the fork that drives the clutch bearing. When pressed against the plateau, there is a distance between the plateau and the disc, disengaging the engine of the gearbox and allowing the gearshift.
The hydraulic drive has the advantages of greater durability, being softer and having automatic adjustment of the pedal height. This means that the driver can not manually adjust the pedal height as is possible in the cable system. In the hydraulic system, however, it is necessary to check the fluid and follow the manufacturer’s recommendation for exchanges, which should generally be done every 50,000 kilometers. If the fluid, the driver will feel the heavy pedal and may not be able to engage the gears.
