Thanks. I have been told by a couple of mechanics that it does, but that probably was regarding brakes.
BTW, does the fact that brakes and clutch share a reservoir make for shorter life for either system than if each had completely separate hydraulics? Does it mean that if one fails hydraulically, the other will (certainly would in the case of leakage, since if one loses fluid, the other automatically has done so)?
Thanks, Dave Mc
