Does the pedal feel any different or is the clutch just not disengaging? If the hydraulics are bad that can usually be felt. The driver (master) cylinder can have a clog or bad check causing the effect. The clutch may actually be failing or the pilot bushing may be seizing causeing the lack of disengagement. There is no spec for free play on the operating lever because there should not be any. Constant contact.

Subject: cluch problem

I have a strange problem on a 85 vanagon clutch.
driving down the road the clutch suddenly engages at the bottom of the pedal travel not the top like normal.
Going down a steep hill at the time, basically shifts ok  and no noise. Fluid down a little but could be due to brake wear,none on the slave cyl.
Master cyl I year old slave orginal.
anyone have the spec for freeplay on the clutch lever on the bellhousing, bently does not seem to have it?
thanks
mike
