Hello, the clutch master cylinder is much easier to replace than it
looks.It has been awhile since I did mine,but I dont think the clevis pin
needed to be removed.Take the cyl mounting bolts off and pull the cyl away
from the pushrod.The rod will hang ok.I used a turkey baster to siphon out
the brake fluid from the resivour.The bleeding was the hardest.Dont replace
the hose that goes from the resivour to the cyl, as rubber fuel line will
not be compatable w/ brake fluid. I pumped and pumped and got
nowhere.Finally , by accident, I got this blead(sp). I filled the resivour
to the verrrrry top and then it pumped up.Maybe try replacing the cyl while
the van is parked on a hill,nose up.The slave cyl is the bit*h,and it is
best to replace both at the same time.
