Clutch
Slave Cylinder
A clutch slave cylinder uses hydraulic pressure from the master cylinder to move the clutch fork or release bearing when you press the pedal. We list 36 slave cylinders from $11 to $209 by LUK, Dorman, AC Delco, Centric and Rhino Pac, all for Chevrolet S10, Camaro and Silverado 2500 HD models.

Signs of a failing slave cylinder
Common signs include a clutch that will not fully release, grinding when you shift, trouble getting into gear, a soft or sinking clutch pedal, and a pedal that stays on the floor. You may also see the clutch fluid reservoir dropping or fluid dripping near the bellhousing.
A failing clutch master cylinder causes similar symptoms, so check for leaks at both ends of the system.
External and internal designs
Some vehicles use an external slave cylinder bolted to the outside of the bellhousing, which is easy to reach. Others use an internal or concentric slave cylinder that sits around the input shaft and combines the slave cylinder with the release bearing. Replacing an internal unit requires removing the transmission.
Check the fitment table for your year, engine and transmission, since one model can use both styles. Most slave cylinders in this group are aluminum.
Installation and bleeding
Use the fluid type your vehicle calls for, usually the brake fluid listed on the reservoir cap. Clean around the line fitting before you open it to keep dirt out of the system.
After installation, bleed air from the system following your vehicle's procedure. Some systems bleed well with a helper pumping the pedal, while others respond better to gravity or vacuum bleeding. Check the pedal feel and clutch release before driving.
Slave Cylinder questions
Should I replace the clutch master and slave cylinder together?
If both are the same age and one has failed, many owners replace both. The other often fails soon after. It also means the whole hydraulic system gets fresh seals and fluid.
Why will my clutch pedal not come back up?
A pedal stuck on the floor often points to a hydraulic problem such as a failed slave cylinder, a failed master cylinder or air in the lines. Check the fluid level and look for leaks first.
What fluid goes in a hydraulic clutch?
Most hydraulic clutches use brake fluid, and many share the brake fluid reservoir. Check the cap or your owner's manual for the correct type before topping up.
