    Doug, the clutch/brake hydraulic system is completely separate from the
Pentosin-filled hydraulic power assist system. The clutch hydraulics work on
brake fluid fed from the brake master cylinder reservoir. The failure of the
steering/hydraulic pump will have no effect on the clutch. It will, however,
eliminate power assist from the braking system.

    If your clutch master cylinder leaks, you will have brake fluid on your
shoes. If you have Pentosin on your shoes, check out the steering rack.
