Hi there. To see if the slave cylinder needs replaced, check the cylinder to see if there is any leaking fluid or if the piston is over extended or stuck. If so, then the slave cylinder would need replaced. If the slave cylinder is not returning, then make sure that the fluid is full in the reservoir and check for air in the system. Plus check the return spring on the fork and make sure that it is intact and not broken. If you need further assistance with your slave cylinder, then seek out a professional, such as one from Your Mechanic, to help you.

Engine revs increase without the car accelerating, particularly on hills. The bite point on the clutch pedal is very high. Gears are difficult to select. Gearbox crunches or jolts when a gear is selected.
Here are some of the warning signs of a bad clutch slave cylinder: Clutch does not work. Clutch pedal sinks to the floor. Clutch pedal feels spongy, soft, or loose.
Changing the slave cylinder is also recommended when replacing the clutch or removing the transmission. Replacing the clutch in isolation may lead to the need for further costly repairs shortly afterwards.
Technician A says clutch slippage can best be diagnosed with the vehicle stopped, parking brake applied, placing the transmission in 4th gear, and slowly releasing the clutch pedal to see if it stalls the engine.
If it is found under the clutch area of the engine/transmission, it`s the slave cylinder that has worn and failed. Clutch master cylinder failures tend to leak clutch fluid onto the carper above the driver foot pedal area. There will be a bit of an acrid odor in the vehicle if this occurs.
Can you drive with a slipping clutch? Although it is technically possible to drive with a slipping clutch, it is very dangerous to do so. Therefore, if you notice any of the symptoms of a slipping clutch then you should get it seen by a local garage or mechanic as soon as possible.
Yes master cylinders can fail without leakage, the clutch master cylinder has a piston inside and there are separate channels for hi-pressure line and return(low pressure) line and their location in the cylinder differs for manufacturers.
That said, there`s really no defined time period for clutch slave cylinder replacement – it`s not a part of your regular maintenance. Chances are that if you own your vehicle for long enough, or if you`ve bought an older vehicle, it`s not unreasonable to think that at some point, the slave cylinder will begin to leak.
Can a slave cylinder cause a clutch to slip? The short answer is, yes, a bad slave cylinder can cause a clutch to slip. It`s not common, however, and occurs only when the slave cylinder is sticking enough to keep the pressure plate partially disengaged.
“Riding” the clutch is the most common reason for premature clutch failure. Even the slightest pressure on the pedal will partially disengage the clutch, causing the release bearing, pressure plate and flywheel to overheat.
That`s when the clutch disc can`t sustain the engine torque in low gear, but in high gear or on light acceleration, it`s fine. You can make it hours, days, or even weeks sometimes when your clutch just starts slipping.
Sudden failure is most often caused by a broken or loose clutch cable, linkable or a failed hydraulic master/slave cylinder. There can also be leaks in the hydraulic line or even the disc could be contaminated with something like dirt or debris.
Difficulty changing gears (or putting the vehicle into gear) is one of the most common signs of a faulty clutch master cylinder. If the master cylinder is leaking or failed internally, the clutch will not fully disengage the transmission from the engine when the pedal is depressed.
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 you need to replace the slave cylinder, the transmission will have to be removed from the engine to gain access to the part. If you need further assistance with the slave cylinder, then seek out a professional, such as one from Your Mechanic, to help you.
The cost of fixing a slipping clutch will depend on several factors, including what`s causing the slippage to begin with. If a worn-out clutch assembly is to blame, you can typically expect to pay somewhere between $1000 and $2,500 for a professional to replace the clutch.
If the clutch slave cylinder develops any sort of leak internally or externally it may cause the pedal to feel spongy or mushy. The pedal may also sink all the way to the floor and stay there when depressed, and may not be able to properly disengage the clutch so the transmission can be safely shifted.
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.
If your clutch pedal goes to the floor, you won`t be able to engage the clutch, and you won`t be able to shift gears. In short, you`ll be stuck. Driving without an operable clutch cable is not recommended. One of our professional mechanics can inspect and repair your clutch system.
Most clutches are designed to last approximately 60,000 miles before they need to be replaced. Some may need replacing at 30,000 and others can keep going well over 100,000 miles, but this is fairly uncommon.
Sit in the driver`s seat with the car off and press the clutch. The clutch shouldn`t be too easy to press down. Pump it back and forth to test its resistance level. If it feels soft and spongy, then this is an early sign that the clutch is starting to wear out.
A malfunctioning clutch can also cause poor acceleration. The reason why is that the clutch is slipping and unable to transfer power from the engine to the drivetrain.
Besides the clutch pressure plate and the clutch disk, clutch slipping causes can often be found in the release system. Additional causes include an incorrectly reworked flywheel or installation of the wrong clutch. Check in case of clutch slipping: Release system wear, freedom of movement, adjustment?
If the issue is left uncorrected, it will ultimately lead to complete loss of drive with the vehicle and may also damage the flywheel due to the excessive heat created from the slipping on the surfaces.
