Causes: clogged filter screen, worn rack, air in the system.
Solutions:
Dirty Screen - remove reservoir and clean the screen. I find spray brake cleaner works well to degrease, then flush with water from the bottom hose port (reverse flow). Allow to dry fully (fans/baking them in an oven/hairdryer etc). Reinstall and fill with fresh fluid per the TSRM. Flush the rest while you are there.
Air - bleed it and add fluid.
Rack - touch your toes when entering the parts counter...$400 for a rebuild, FAR more for new. GIANT PITA to get in and out with the engine in...
