Caster Brakes
One UHMW brake piston each caster;
2 total.
Replace UHMW piston if its length is less than 3.2cm
(1
1 ⁄
4
in). Also replace piston if missing, damaged, tilted,
or top of piston is visible. Measuring the length requires
at least partial disassembly of the caster pivot, and is not
recommended unless there are indications that the pis-
ton might need replacement.
To set spring tension with a new piston:
a. Loosen jam nut
and back out set screw .
b. Drive screw in (down) until it contacts spring plate .
c. Drive screw in another 1 inch (2.5cm).
d. Tighten jam nut.
Use more tension as needed to eliminate caster vibration
during highway transport.
