Well......i don't agree, not that you are not right...but something is
Wrong in there...
Other car i work on have a second spring in the housing to help the
hydro / cable system to bring the bearing back.

Another thing, some vans are worse than others. An 84 that i worked on
just had a bearing failiure/seizure after 10k miles.
On some of the van i work on the bearing is to dificult to push in. I
wonder if some kind of air pocket make is way is the system wile vans
are left without a clutch for some time in the shop.

Anyway, i will bleed the system just in case. am blamming old clutch
cylinder.....

Thanks, Ben

>The Clutch system does not have the ability to pull the release bearing away from the pressure plate. In fact, the operating cylinder, (slave) has a spring which will always put some pressure on the bearing. This is normal. Yes it does keep the bearing spinning but the load is very light. The release bearing can still last well past 100K and usuaully something else will fail reqiuring the the clutch to need service first.
