Internal and external leaks are also typical problems for slave cylinders.Seldom are these cylinders rebuilt; rather, they are replaced.Replacing a slave cylinder is rather straightforward on most vehicles.Simply disconnect the hydraulic lines and unbolt the unit.If it appears that the piston of a slave cylinder is seized in its bore, check the movement of the release fork and lever at the clutch before replacing the slave cylinder.Leaks may also result from damaged or corroded hydraulic lines.These lines should be replaced, if damaged, with the same type of tube as was originally installed.
