Assembly
With the brake cylinder resting on its large end, insert
the piston into the brake cylinder. Be careful not to cut
the O-rings or backup rings.
Lubricate the outside of the piston with oil or grease.
Lubricate O-rings and backup rings with oil and install
them on the brake piston. The concave surface of the
backdup ring must be next to the O-ring. Let the
assembly set for 10 minutes in order for the O-rings and
backup rings to return to their original shape.
Here are the backup rings and O-rings installed correct-
ly. The backup rings must be to the outside of the O-
rings.

Next, place the backup plate over the spring guide so
that it rests on the top spring. Then, insert the spring
guide, springs and backup plate into the brake cylinder.
The cross-section above shows the correct assembly of
the springs and backup plate on the spring guide.
Install the eight (8) belleville springs over the spring
guide. The first one should rest against the snap ring on
the spring guide, with the concave side facing the snap
ring. The second spring should be installed with its con-
vex side facing the snap ring. Alternate the remaining
six (6) springs until all eight (8) are in place.
