A hydraulic clutch relies on steel tubing and special seals within a slave cylinder. The steel tubing is subject to corrosion and the seals can leak or blow out. A leak is not a big deal as any of the hydraulic components can be refurbished, or replaced, and new steel tubing (or preferably newer approved material such as Ni-Copp or Cunifer tubing) can be fabricated right at your location to effect the repair. If you desire that this issue be diagnosed and repaired, simply request a clutch inspection and a certified Mechanic will be dispatched right to your location to both diagnose and estimate this for you.
How to Identify and Fix Common car Problems ?

Broken Clutch Cable: The most common reason to have a clutch pedal that goes all the way to the floor is a broken clutch cable. This is extremely common, particularly on older cars. Replacing the cable will allow you to engage the clutch and change gears once more.
Common signs of a clutch fluid leak are difficulty shifting or grinding noises while shifting, clutch pedal staying close to the floor, and dirty or low clutch fluid. Bar`s Leaks Hydraulic Manual Clutch Fluid with Stop Leak stops small leaks (adding fluid once per month) and medium leaks (adding fluid once per week).
Leaking Master Cylinder: The clutch master cylinder is subject to leaking at several points. One is the plastic fluid reservoir. However, the more likely problem is that the master cylinder seal has failed. Brake fluid is corrosive, and it will eventually degrade the seal, causing it to leak.
Air as cause of malfunction
As far as the hydraulic clutch is concerned, the following symptoms may occur: Change of the pedal travel. Difficulties in disengaging the clutch. Imprecise pedal feel.
If there is air in the system, you do not get enough pressure and the clutch is not able to fully engage. Bleeding the clutch is a process in which you remove all the fluid currently in the system, getting out all the liquid and air, and replacing it with purely liquid.
Clutches tend to fail in one of two ways – either suddenly or gradually. With a sudden breakdown, the clutch ceases to work entirely and the car won`t move. With gradual failure, you may experience problems such as the car not stopping when you press the pedal.
To remove the air from your clutch system you need to push or pull the air down through the fluid line to the bleeder valve on the slave cylinder. To keep things clean you should attach a tube to the nipple on the bleeder valve. If you use a clear tube it can be easy to see when all the air has exited the system.
Most clutch leaks occur at the master cylinder (under the dash) or at the slave cylinder (on the side of the transmission). Look for wetness around the shafts on both of these cylinders. When the internal seals fail fluid can leak out when the shaft enters the housing.
Your clutch uses brake fluid to transmit hydraulic pressure to activate your clutch. Brake fluid adsorbs water from the air meaning that over time this water can corrode internal metal parts such as the inside of the clutch master cylinder and clutch slave cylinder.
If you notice a change in how your clutch feels, then this can be a sign that something isn`t working as it should. A soft or spongy feeling can indicate that your brake fluid is low and causing the clutch slave cylinder to struggle.
When air is present in a hydraulic system, the desired instant system reaction is slowed and results in a slower actuator response or a “spongy feel.” This is due to the compressible nature of the trapped air. The air contained in a system is alternately compressed and decompressed as the actuator is cycled.
If clogged badly enough, air will not be able to pass through the filter-breather, which could create a partial vacuum in the reservoir. This, in turn, could cause cavitation of the pump, which usually results in premature pump failure.
There could be a leak on the slave cylinder causing the slave cylinder not to operate. Also, check the pin to the clutch pedal and make sure that it is hooked up to the clutch master cylinder. Check the lines and make sure that they are not cross threaded, which will not seal and cause a leak.
Driving a car with a faulty clutch can cause further damage to your gearbox, starter motor or shifter. It is important to resolve any damage spotted with your clutch. However, it is still essential to know how to drive a car with no clutch.
The clutch is subjected to constant friction, so it is unsurprising that it will wear out eventually. You may find that your clutch lasts 10,000 miles before you need to get a new one or you could drive 150,000 before it gives up.
The average lifespan of a clutch is anywhere between 20,000 to 150,000 miles. Luckily, your clutch will likely give you ample notice that something is going wrong. Don`t get left at the side of the road with a vehicle that won`t shift into gear.
Most hydraulic clutch systems have their dedicated master cylinder; however, some vehicles use one master cylinder for both the brake system and the clutch system. Any time you open the hydraulic system, you will need to bleed it to remove air pockets.
If the clutch pedal is going soft even after it is bled, then that is an indicator that there is either a problem with the master cylinder or the slave cylinder.
Clutch master cylinders develop leaks both internally and externally. Check for an external leak on the floorboard behind the clutch pedal or the engine compartment`s firewall. If there is a loss of pressure after the clutch is applied, and there are no external leaks, suspect an internal leak.
Even though the clutch pedal is sturdy, it will still wear off or break at the pivot, pedal arm or your clutch. Driving a car with a faulty clutch can cause further damage to your gearbox, starter motor or shifter. It is important to resolve any damage spotted with your clutch.
