Reply to "BLEEDING CLUTCH SYSTEM"

Dick, I recently had a problem bleeding my hydraulic clutch in a recently purchased Toyota T100 truck. After changing my clutch disc, pressure plate and T/O bearing, my clutch refused to release. I tried the gravity bleed followed by the 2 man pump and hold method which didn't work after many attempts, still leaving a dead pedal. I purchased a new clutch master and slave and the problem still persisted. Eliminating a bad clutch or master, I purchased a Mity Vac vacuum bleeder. This also didn't work and the same problem persisted. A friend of mine came over to help. He loosened the stop bolts (there were two of them, an upper one for the clutch pedal height and a lower one for floor stop). Sure enough after the first attempt at the bleed, it worked! My friend said that the 1/4 to 1/2 inch of restriction from the lower stop bolt kept the piston from it's full stroke in the bore and allowed air to remain there. I forget if there were any stop screws in the Mangusta, if there are it may be your problem.
