A squeak from the slave cylinder when the pedal is released often indicates a lack of lubrication or a worn-out component within the hydraulic system. The release of the clutch pedal can cause the internal parts of the slave cylinder to move against each other, resulting in noise if they are not properly lubricated. Additionally, a faulty or failing slave cylinder may also produce unusual sounds due to internal wear or improper alignment. It's advisable to inspect the cylinder and surrounding components to determine the exact cause.
