5. Note the position and orientation of the piston cup(s), washers, and springs. Replace the worn
parts, then reassemble them in reverse order. Tighten the locknut until it is just barely possible
to turn the piston cup and washer assembly on the stem. The correct piston cup shape is
shown on the left side of the above figure.
Do not
overtighten the locknut, as this causes the
piston cup to deform to the shape shown on the right side of the figure and may cause the pis-
ton to bind in the cylinder.
