I have a 91 cherokee 4.0L with a 5spd. The clutch master cylinder was replaced in 2002, 2005 and 6 mos. later in 2006 and seems to be causing problems now. Is this a weak link in the clutch? All other clutch parts were replaced about 25k miles ago.

 

Mine is probably 4 years old & drove hard, you might try OEM part.

 

try to find a new one, rebuile are not very long lasting
