I have rebuilt several Cleveland cylinders, both master and slave with no problems. Typically, either the O-rings fail, there is crud build up. or at worst and rarely, there is corrosion in the cylinder walls.

Pull it apart and give it a look. Then decide if you need a new one.

I can second that opinion. Just be sure when reordering the O-ring to
get the right one. They are different for hydraulic fluid or
(automotive) brake fluid. My ASW 24 uses hydraulic fluid, but I'm not
sure about the ASW 20.
