Clutch line will not vacuum bleed - clogged???
 

1989 TOYOTA PICKUP BASE MODEL, 2WD, 4 SPEED.

The truck was used infrequently and then sat unused for a couple of years.
The master cylinder looked like it was filled with dark brown paint or thin pudding.
Replaced clutch master cylinder with new Aisin unit. Filled with DOT 3 fluid.
I could not get any fluid or air to flow from the slave cylinder. I used a vacuum pump, 15 inches,
still no fluid. The setup held vacuum for some time. I vacuumed both with the clutch up and down.
I took the plug completely out; still no fluid.
It seems that the sludge in system has plugged the hydraulic line and/or jammed the slave cylinder.
It was difficult for me to work under the dash panel and under the truck. No lift here. I have not tried to blow it out.
Ideas and comments would be appreciated.

undo your line , both ends , compressed air and blow it out , most likely clogged .. your slave cly is most likely seized .
this is a gravity bled system , so you should be able to crack the bleeder on the slave until it drips , and then its bled .

SLACKER,
Thanks for the comments.

I had a similar issue a few years ago. My solution was to replace the clutch line completely. New master cylinder, new clutch line, new slave cylinder. No more problem. :)
