Good day. 1988 YJ. I just bought this and the clutch didn't work very well. It was hard to put in gear. The pedal was very light. I drained the old fluid, which was black as night, pumped through new fluid and bled all the air out. I test drove it and it seemed to work good. I let it sit over night and test drove it again and had to pump the clutch 20-25 times before it worked. Test drove it for 1/2 hour and worked beautiful.
I cant tell if the slave is leaking cause it is inside the bell housing and need to pull the tranny. It doesn't seem to be leaking.
Could this be the master cyl seals are toast?
Can the slave cyl fail and not leak?
If there was still air in the system, would that cause me to have to pump the clutch up?
I thought I bled all the air out of the system, but should I try to bleed it more?
