Thankfully on most models, the hydraulic lines are covered in braided steel or double lined. While it is certainly possible to damage this line it is not common. I have broken way more clutch cables in my lifetime than I have broken hydraulic clutch lines. There are rubber seals on the pistons of both the slave cylinder down on the engine and the master cylinder on the handlebar. These seals can be damaged by wear or from debris in the hydraulic fluid.
All clutch systems have written on the cap of the master cylinder reservoir what fluid is recommended. If the wrong fluid is added it can cause seal and hydraulic line damage that eventually leads to the clutch crying enough. Obviously there is also the chance of the master or slave cylinder getting damaged in a crash. It is much less likely for the slave cylinder to be damaged but as the master cylinder reservoir sits on top of the handlebar and houses the clutch lever it is susceptible to damage in a crash and can be expensive to replace.
More expensive is if the final-drive chain derails and hits the slave cylinder. There are two reasons you would want to bleed your hydraulic clutch. You have to do it when you change the fluid but you may also need to do it to get rid of air in the line. They preceded hydraulic clutch systems and were commonly used on cars up until the s. A mechanical clutch is a pretty simple system. A steel cable connects the clutch pedal directly to the clutch assembly. Pressing or actuating the pedal moves the cable.
This moves the clutch fork, which actuates the clutch throwout bearing. This then disengages the clutch plate. Even those who grew up driving modern manual transmission cars may find that mechanical clutch cars take some getting used to.
The direct connection of a mechanical clutch means the driver will typically feel more engagement when shifting. A hydraulic clutch uses hydraulic fluid instead of a cable to move the clutch disc.
It relies on reservoir cylinders to control pressure in relation to how the clutch pedal is depressed. This type of clutch has a reservoir containing hydraulic fluid, and when you push down on the clutch pedal, the fluid becomes pressurized. A hydraulic clutch uses fluid to actuate a hydraulic piston. The piston then engages or disengages the clutch through a series of connections.
The clutch master cylinder converts the pressing of the clutch pedal into hydraulic pressure. This power is then transferred to the clutch slave cylinder. A rod extends from the slave cylinder, actuating the clutch fork. The clutch fork then moves the clutch release bearing. This, in turn, releases the clutch pressure plate, disengaging the clutch.
CRC is very easy and quick to replace as it is always located outside the transmission housing about 30 min replacement for professionals. If you change the clutch master cylinder, it is recommended to change the slave cylinder CSC at the same time, as both units typically fail around the same time.

Valeo Tip In almost all cases, the clutch fluid is the same as the brake fluid. Semi-hydraulic CRC is very easy and quick to replace as it is always located outside the transmission housing about 30 min replacement for professionals.
Technologies The clutch release cylinder CRC may need to be replaced if:. One does not have to adjust the clutch or worry about the greasing of the wire in hydraulic clutches.
The hydraulic clutch combats mechanical clutch in terms of quality as well. The cable wire clutches are vulnerable to corrosion and can break easily after aging. The mechanical clutch requires lubrication periodically. And, these might get struck if the wires get bent too piercingly. You do not have to worry about all this stuff in the hydraulic clutches. These are easy to modulate and consists fluid to work.
One might have to replace the fluid after a number of years for better performance. The hydraulic setup is a little expensive if the seals of cylinders leak in any case.
But, hydraulics are much better in terms of quality. So, these were some factors where we discussed hydraulic clutch vs mechanical clutch.
You can go for the one that suits your car and pocket well.
